INTRODUCTION:

Lantana camara is a flowering ornamental plant of the Verbenaceae family. Lantana camara probably arrived in India before the nineteenth century. Lantana camara flourishes in India's moderate to heavy summer rainfall and well-drained sloping terrain1. While most varieties prefer fertile organic soils, they can also survive on siliceous sands and sandstone-derived soils with moderate depth and ideal conditions, such as year-round precipitation2.

 

The plant is indigenous to tropical settings and has several strains and varieties with different looks In India, L. camara is known by many names, such as Raimuniya in Hindi, Chaturangi and Vanacehdi in Sanskrit, Arippu and Unnichedi in Tamil, Aripoov, Poochedi, Konginipoo, and Nattachedi in Malayalam, Thirei, Samballei, and Nongballei in Manipuri, Tantani and Ghaneri in Marathi3,11,13. Lantana camara is a well-known medicinal plant in traditional medicine, and recent scientific studies have highlighted its potential use in modern medicine. Lantana camara's medicinal properties as well as its potential for further scientific investigation into the development of effective therapeutic compounds. It's a woody, straggling, evergreen, and fragrant wild plant. The stems and branches are sometimes thorny4. The leaves are grouped in opposing pairs and are broadly oval, bright green, and rough with short hairs. They have sharply serrated edges and a wrinkled look due to numerous veins. Flower heads comprise 20-40 flowers, which are normally 2.5 cm across; the colours of the flowers range from white, cream, or yellow to orange, pink, purple, and red, with little circular heads that are often bicolour5. The fruits are fleshy berries in clusters that are glossy and globose in shape, green in colour, and become black when ripe. The root structure is quite robust, comprising a main taproot and a mat of several shallow side roots. Lantana camara can be used as mulch, firewood, and herbal medicine, among other things6. The chemical composition of lantana camara has been well investigated, especially in India. The roots cure toothaches, the blossoms ease children's chest problems, and the plant's leaf oil is used as an antiseptic for scars. The leaf extract of Lantana camara possesses nematocidal, fungicidal, insecticidal, antibacterial, and anti-proliferative qualities7,8. The extract from lantana camara shoots exhibited potent antioxidant properties. The WHO recommends the use of plants as the ideal way to access the majority of drug classes9. Lantana camara is a medicinal plant used in folk medicine to cure many diseases. The plant parts of Lantana camara, including leaves, flowers, roots, fruits, and the essential oils have been extensively investigated for their phytochemical and bioactivity profiles10.

Species

Lantana camara

 

Lantana camara is a widely distributed plant that grows at elevations of up to 2000 meters in tropical, subtropical, and temperate climates. The species name (camara) is probably derived from the West Indian17. Lantana camara develops in little clusters smaller than 1m in diameter in its natural home of tropical America. Lantana camara frequently forms dense, monospecific thickets that range in height and diameter from 1 to 4 meters. Lantana camara has been naturalized in around 60 countries18. The lantana weed is established in several countries and islands including Yap, the Galapagos, Palau, Saipan, Tinian, the Solomon Islands and the Futuna Islands. The plant grows in disturbed habitats such as roadsides, railway lines and ditches19.

MATERIAL AND METHODS:

Plant collection:

Lantana camara is gathered from Majhaun, Pondha, and Dehradun (Uttarakhand) and recognized by a botanist from botanical survey of India by northern regional center, Kaulagarh road, Dehradun, Uttarakhand, India. First, the fresh leaves of the harvested plant were separated and properly washed with running tap water, followed by distilled water, to remove dust and other undesired substances. The leaves were then cleaned with distilled water and shade dried at 60°C for 48 hours. The dried leaves were grind into a coarse powder in mortar and pestle in (Fig 2) and sieved through a 40-number sieve before being stored in an airtight bottle for extraction.

Chemicals and reagents:

Ethanol, petroleum ether, chloroform, hydrogen peroxide, potassium dihydrogen phosphate, sodium hydroxide, ascorbic acid, lead acetate, Mayer’s reagent, sulfuric acid, ferric chloride copper sulphate.

 

Extraction by Maceration:

First, weigh 50g of powered leaves and add polar solvent (ethanol) in the first iodine flask, mild polar solvent (pet-ether) in the second iodine flask, and non-polar solvent (chloroform) in the third iodine flask at a ratio of 1:5(w/v), around 250ml of each solvent, respectively27,28. Close the bottle tightly to prevent solvent evaporation and contamination. Store it at room temperature for 3-7 days, shaking occasionally. After 3-7 days, filter the extract using Whatman filter paper. Label each extract with the solvent and keep it in airtight containers in a cool, dark place29,30.



Qualitative Phytochemical Screening of leaves extract:

Secondary metabolites in ethanol, pet-ether, and chloroform extracts of Lantana camara leaves were studied. Phytochemicals tested for include alkaloids, flavonoids, glycosides, tannins, carbohydrates, phenols, terpenoids, steroids, oil and fats and proteins (Fig.3).

 

Test for Flavonoids:

A preliminary test for flavonoids involves adding 2ml of lead acetate to 1ml of Lantana camara leaf extracts, resulting in a yellow and white precipitate31.

 

Test for Alkaloids:

1ml of each extract was obtained, and a few drops of Mayers reagent were applied to each test tube; the development of a white creamy colour indicated the presence of alkaloids31.

 

Test for Tannins:

Three drops of 0.1% lead acetate solution were added in 1ml of each leaf extract filtrate and the presence of tannins is precipitate when creamy gelatinous appears32.

 

Test for Terpenoids:

2 ml of leaf extract filtrate was mixed with 6 drops of chloroform and heated in a water bath for a few minutes. Then, six drops of concentrated H2SO4 were added. The reddish-brown interface confirmed the presence of terpenoids32.

 

Test for Steroids:

1ml of chloroform and 1 ml of concentrated sulfuric acid were added to 1ml of the filtered leaf extract. The appearance of upper red and lower yellow with green fluorescence indicates that the test for steroids is positive33.

 

Test for Proteins:

When the leaf extract filtrate is mixed with 4% NaOH solution and a few drops of 1% CuSO4 solution, a violet colour develops, indicating the presence of protein34.

 

Test for Oils and Fats:

A drop of extract solution dropped on the filter paper a spot was created and oil staining on the filter paper shows the presence of oils and fats35.

 

Test for Phenol:

Add three to four drops of ferric chloride solution to 2ml of extract. The presence of phenols is indicated by the formation of a blue-black colour35.

 

Test for Carbohydrate:

A few drops of H2SO4 were added to 1 ml of leaf extract. A purple or reddish hue indicates a successful test 36.

 

Test for Glycoside:

Plant extract samples were mixed with one millilitre of glacial acetic acid and let to cool. After cooling, conc. H2SO4 was cautiously poured around the test tube's walls after two drops of FeCl3 had been added. The reddish-brown ring that developed where two layers met indicated the presence of glycosides36.

Instrumentation:

UV spectrophotometer (Shimadz Spectrophotometer UV-1800), the foundation of UV- spectroscopy uses the idea that light of a particular wavelength is absorbed by electrons moving from their ground state to an excited state, which lowers the quantity of light that is transmitted37. The Lambert-Beer rule states that there is a substantial correlation between the substance's concentration and its absorption spectrum38. An absorption measurement at 230 nm was used to determine the phytochemical content of Lantana camara leaf extracts using a UV- visible spectrophotometer39.

 

Antioxidant Assay by Hydrogen peroxide radical scavenging activity assay:

Preparation of Phosphate buffer (0.2M, pH-7.4): In accordance with the Indian Pharmacopoeia 1996 guidelines, 0.2M potassium dihydrogen phosphate and 0.2M sodium hydroxide solutions were made. To make phosphate buffer (pH-7.4), 50ml of potassium dihydrogen phosphate solution was placed in a 200ml volumetric flask, followed by the addition of 39.1ml of 0.2M sodium hydroxide solution and the final volume being adjusted to 200ml with distilled water40. To create the free radicals, 50 millilitres of phosphate buffer solution were added to an equivalent volume of hydrogen peroxide. The solution was then left at room temperature for five minutes to complete the reaction. Getting the stock solution ready 1000 millilitres of distilled water mixed with 100 milligrams of plant ethanol extract. From this stock solution. Three test tubes were filled with 1ml, 2ml, and 3ml of solutions, followed by progressive dilutions with identical solvents to reach a final volume of 10ml. The concentrations for each extract were 10µg/ml, 20µg/ml, and 30µg/ml, respectively. Similarly, the standard solution (ascorbic acid) is prepared41. In a UV spectrophotometer, the absorbance at 230nm was calculated in comparison to a blank solution that included phosphate buffer solution devoid of hydrogen peroxide. The following formula was used to get the H2O2 inhibition percentage42.

H2O2 inhibition % = A0-A1/A0 x100

Where

A0= Absorbance of control, A1= Absorbance of test

 

RESULTS:

Results of qualitative phytochemical screening of leaves extract of Lantana camara: According to this study, Lantana camara leaves the presence of almost all important phytochemicals, such as proteins, phenols, alkaloids, terpenoids, tannins, glycosides, proteins, and carbohydrates, was shown in the most effective extraction solvent is ethanol extract. Non-polar substances such as oils, lipids, terpenoids, and steroids were abundant in petroleum ether extract. A modest variety of phytochemicals, including flavonoids, alkaloids, terpenoids, steroids, phenols, and glycosides, were detected in the chloroform extract represented in table 4.

Nearly all significant phytochemicals, including proteins, phenols, alkaloids, terpenoids, tannins, glycosides, proteins, and carbohydrates, are found in lantana camara leaves. It was shown that ethanol extract is the most efficient extraction solvent. Thus, the ethanol extract utilized to investigate the scavenging activity of H2O2.

 

Result of Antioxidant Assay by Hydrogen peroxide radical scavenging activity:

The Ethanol extract of Lantana camara leaves' capacity to scavenge H2O2 in contrast to ascorbic acid, a common antioxidant, is demonstrated in Table 5 and Figure 6. Three distinct concentrations of 10, 20, and 30µg/mL were used for the experiment. Ascorbic acid demonstrated a 45.2% suppression of hydrogen peroxide radicals at 10µg/mL, but the ethanol extract demonstrated a 32.5% inhibition. The ethanol extract showed enhanced scavenging activities of 54.8% and 69.3%, respectively, when the concentration rose to 20 µg/mL and 30µg/mL. Ascorbic acid, on the other hand, showed greater inhibition at the same concentrations: 66.4% at 20µg/mL and 81.0% at 30µg/mL. A dose-dependent rise in the percentage of inhibition for both the ethanol extract and the standard can be seen from the graphical depiction (Figure 4). However, at every measured dose, ascorbic acid and ethanol extract continuously shown antioxidant activity.

DISCUSSION:

A variable profile of phytochemicals was found in the research of Lantana camara leaves, and they varied according to the extraction solvent. A wider variety of phytochemicals, including proteins, phenols, alkaloids, terpenoids, tannins, glycosides, flavonoids, and steroids, were extracted using ethanol, which turned out to be the most efficient solvent. This is in line with the fact that ethanol is very polar, making it easier to extract polar and some semi-polar substances. On the other hand, non-polar substances including oils, fats, terpenoids, and steroids were mostly extracted by petroleum ether and chloroform, which are non-polar and somewhat polar solvents, respectively. The effectiveness of the ethanol extract was further validated by the antioxidant test, which revealed a concentration-dependent rise in hydrogen peroxide radical scavenging activity. But it always worked as well as ascorbic acid, the common antioxidant.

 

CONCLUSION:

The study demonstrates to the quantity of phytochemicals with possible antioxidant properties found in Lantana camara leaves. The most effective solvent for removing a variety of these bioactive substances was discovered to be ethanol. Despite being just as strong as the conventional ascorbic acid, the ethanol extract showed significant antioxidant action. According to these results, Lantana camara shows promise in herbal medicine and may be investigated further for its potential as a treatment.
