Phytochemical analysis and antioxidant activities of Lantana camara and Lantana montevidensis extracts

Physalis peruviana calyces are used extensively in folk medicine. The crude ethanolic extract and some fractions of calyces were evaluated in order to explore antioxidant and anti-inflammatory activities. The anti-inflammatory activity was evaluated by the TPA-induced ear edema model. The antioxidant in vitro activity was measured by means of the superoxide and nitric oxide scavenging activity of the extracts and fractions. The butanolic fraction was found to be promising due to its anti-inflammatory and antioxidant activities. Therefore, a bio-assay guided approach was employed to isolate and identify rutin (1) and nicotoflorin (2) from their NMR spectroscopic and MS data. The identification of rutin in calyces of P. peruviana supports the possible use of this waste material for phytotherapeutic, nutraceutical and cosmetic preparations.

Phytochemical Composition

Berberis lyceum Royle has such pronounced medicinal values that it is used as cure of many diseases and has exhibited great therapeutic effects among the local communities throughout the world. The present research was carried out to evaluate the quantitative ethnobotanical status and phytochemical analysis of B. lyceum. Regular field trips were arranged to the study area (Shangla District) in August 2017 to October 2019 and interviews with 100 residents (age range: 30 to 50 years) were conducted. The approach adopted for ethnobotanical data was semi-scientific as the inhabitants were not aware about the modern names of some diseases and therefore physician prescriptions were also consulted. Ethnobotanical data were examined using relative frequency of citation and % use value. The % use value of B. lyceum indicates that the people of District Shangla mostly used it for curing of different diseases. In spite of tremendous uses the plant still survived in this area mainly due to the non-accessibility for humans of the mountain tops; otherwise, increase in anthropogenic activities even in these hilly areas poses a threat of the eradication of this plant. To correlate the folkloric uses with its phytochemical composition, HPLC (high performance liquid chromatography) analysis was performed and a total of six phenolic compounds (quercetin, chlorogenic acid, berberine, rutin, mandellic acid, and hydroxy benzoic acid) were identified in its root. As most of the health complications are correlated to oxidative stress therefore in vitro antioxidant activity were also performed using DPPH (2, 2- diphenyl-1-picrylhydrazyl) and ABTS (2, 2′-azinobis-3-ethyl benzo thiazoline -6- sulfonic acid) assays. The observed antioxidant potential may most probably be due to berberine and chlorogenic acid that were present in highest concentration in the analyzed extract. The effectiveness of the selected plant as remedy for a number of diseases (that were pointed out by the local community) may be due to its phytochemical composition especially berberine and chlorogenic acid as oxidative stress is the root cause of many diseases. The plant extract exhibited high antioxidant potential (DPPH IC50 = 165µg/mL; ABTSIC50 = 110µg/mL) in relation to the detected concentration of berberine and chlorogenic acid. It can be inferred from experimental results that the ethnopharmacological efficacy of this endangered species may be due to its phytochemical composition and antioxidant activities. This case study helps to revive the importance of B. lyceum in local communities and emphasizes the need for its conservation.

Objective: The present study was undertaken to assess the α-amylase inhibitory activity and antidiabetic experimental catfish model and antioxidant properties of Piper betle L. ethanolic (PBE) extract.Methods: The phytochemical analysis of PBE extract was performed. The PBE extract was tested for their inhibitory effect on the α-amylase assay, which compared to the control, acarbose. The absorbance was read at 540 nm using a spectrophotometer, and IC50 values were calculated. In this present investigation, diabetes mellitus was induced in catfish, Clarias gariepinus by epaxial musculature injection to glucose and standard drug, Metformin hydrochloride. After 24-h incubation, the treated fishes were dissected, and the blood, liver, tissue samples, and epaxial musculature regions were collected. In addition, the antioxidant properties of PBE were determined by 2,2-diphenyl-l-picrylhydrazyl (DPPH) radical scavenging and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging (ABTS) assays.Results: The phytochemical screening of PBE revealed the presence of alkaloid, flavonoids, tannins, phenol, glycosides, sterols, saponins, and quinines. Furthermore, the values of (μg/ml) 3.038 and 7.672 α-amylase enzyme inhibition were excellent activity when compared to the acarbose. Moreover, elevated the glucose level (mg/dl) was estimated in blood 1.9±0.35, liver 0.5±0.25, tissue 0.2±0.25, and epaxial musculature 0.8±0.2 after 24-h incubation. The antioxidant effect of maximum activity was found in PBE; IC50 values (μg/ml) of DPPH and ABTS were 9.362 and 6.606, respectively.Conclusions: These studies might be responsible for the P. betle L. that was used as the new source of antidiabetic and antioxidant agents.

Objective: In the present study is investigated of phytochemicals and antioxidant activities of the leaf extracts from Meliosma simplicifolia (L.). Methods: The seaweed sample was subjected to extraction with solvents of different polarities (hot water, methanol, acetone, chloroform, and petroleum ether) and screened for phytochemicals according to standard methods. The ability of the plant extract to act as hydrogen/electrons donor or scavenger of radicals was determined by in vitro antioxidant assays using 2,2-diphenyl-2-picryl-hydrazyl free radical (DPPH) scavenging, reducing power assay, and superoxide radical (O2•) scavenging activity. The ICPMS and GC-MS analysis of the methanol leaf extract of M. simplicifolia was revealed the presence of antibacterial. Results: Phytochemical analysis revealed the presence of Preliminary metabolites Quantitative studies of estimated phenol, flavonoid and tannin, as for the methanol extract of stem showed the highest content of phenolic compounds (40.71±0.94 GAE mg/100). Antioxidant activities were concluded the estimation M. simplicifolia leaf for as followed the studies. In leaf the highest DPPH scavenging activity (132.3 μg/ml), ICP-MS analysis of the leaf extract showed the presence minerals such as Mg, Fe, Cu, Na, and Zn in excess. The leaf extract of the plant was also tested for its antibacterial activity and results confirmed that it has potential activity. Conclusion: The preliminary studies in the methanol extract of the leaf of M. simplicifolia are suggestive of the antibacterial potentials of the methanol extract of leaves of M. simplicifolia.
