Introduction: Cancer is considered as the prime lethal disease that affects different organs of the body. Even with the rapid developments in the medical sciences, there are no proper medicines to cure specific kind of cancer without side effects. The inhibition of tumour cell growth without side effects either by the use herbal or synthetic drugs is considered as an important target in cancer therapy. In traditional medicinal system A. semecarpifolia stem bark is the prime source of herbal drug to treat lymphatic and skin cancers. Objective: The purpose of this study is to evaluate the anticancer potential of A. semecarpifolia stem bark extracts against some cancer cell lines. Methods: The in vitro anticancer activity was evaluated against DLA, EAC, HeLa, HepG2 and L929 cell lines by trypan blue dye exclusion assay and SRB assay. Results: The results of the anticancer activity revealed that, when compared to standard drug Cyclophosphamide, SBPEE and SBCE of A. semecarpifolia showed significant anticancer activity against DLA and EAC cell lines, without causing any toxicity to the normal mouse fibroblast cells L929. Whereas, none of the three extracts showed cytotoxicity against HeLa, HepG2 and L929 cell lines. Conclusion: The present study suggested that, SBPEE and SBCE possesses significant cytotoxic activity against DLA and EAC cell lines, which confirms the traditional medicinal claim of A. semecarpifolia as a potent anticancer plant against lymphatic and skin cancer.

Background: Bridelia scandens Wild. (Euphorbiaceae) leaves are widely used to cure asthma, bronchitis pleurisy, exudation, sores in mouth and genital cancers. Objective: To evaluate antibacterial activity of the leaf calli methanol extract (LCME). Materials and Methods: Mass production of leaf calli was established on MS medium supplemented with 0.5 mg/L BAP and 0.5 mg/L 2, 4-D. Methanol extract of the dried calli was subjected to HR-LCMS analysis, antibacterial screening of the extract was carried out against human pathogenic clinical isolates. Molecular docking study of HR-LCMS identified compounds was performed by docking with bacterial enzyme DNA gyrase. Results: HR-LCMS analysis of LCME shows that the compounds azaperone bifonazole, fusidic acid, lasalocid and quinine as the major constituents. The antibacterial screening of LCME against clinical pathogens showed significant bactericidal activity against the strains Staphylococcus aureus (17.67\±0.88 mm.d.), Streptococcus pneumonia (13.67\±0.33), Pseudomonas aeruginosa (16.33\±0.67), Salmonella typhi (17.67\±0.33), and Vibrio cholera (15.33\±0.33) as compared to the standard drug ciprofloxacin. The molecular docking of lasalocid against the bacterial enzyme DNA gyrase exhibited good binding affinity of -4.9 kcal/mol, good drug likeness (2.5589), 2 hydrogen bonds and hydrophobic interaction with 7 amino acid residues, so that lasalocid processes good inhibitor as compared to other 4 compounds. Conclusion: LCME of Bridelia scandens showed significant antibacterial activity against Staphylococcus aureus and Salmonella typhi. Lasalocid is the major phytocomponent of LCME which exhibited good inhibitory activity against bacterial enzyme DNA gyrase. This investigation supported traditional claim of LCME as potential antibacterial drug.\

Introduction: The present study was contemplated to evaluate the anti-inflammatory and analgesic potentials in peels of some commercially grown Citrus fruits of South India viz, Lime (Citrus aurantifolia), Orange (Citrus reticulata), Sour Orange (Citrus aurantium), Pomello (Citrus grandis) and Citron (Citrus medica). Methods: The peel of the fruits were separated and subjected to cold extraction using 70\% alcohol. The extracts obtained were screened for the presence of phytoconstituents by qualitative phytochemical analysis; the anti-inflammatory activity of extracts at 250 and 500mg/Kg body weight concentrations were assessed by in vivo Carrageenan induced rat paw edema model and in vitro HRBC membrane stabilization assay whereas Tail immersion and Hot plate methods have been used to evaluate their analgesic property. Results: The results revealed that, all extracts treated animals have shown significant decrease in paw edema volume at 3rd and 4th hour of treatment and increase in reaction time in tail immersion and hot plate readings at 120 and 150 min and are comparable to the standards. From the results it was evident that Citron peel extract exhibited significant antiinflammatory and analgesic property in all models. Preliminary phytochemical investigation revealed that extracts were bestowed with presence of flavonoids, terpenoids, steroids, glycosides, alkaloids, carotenoids and phenolic compounds which might be responsible for the antinociceptive and anti-inflammatory activities. Conclusion: From the results it was evident that all citrus fruits have prominent activity in terms of parameters assessed in a dose dependent manner and are more effective in the later phase. The study thus documents that Citrus peels are good sources of anti-inflammatory and anti-nociceptive agents.

Background: Litsea glutinosa (Lauraceae) stem bark is widely used in folk medicine as a hepatoprotective, anti-diarrheal and anti-dysenteric drug but there is a lack of information about its toxicity. Objective: To evaluate cytotoxicity and acute toxicity of the stem bark ethanol extract (BEE). Materials and Methods: In vitro cytotoxicity of BEE was measured against breast adenocarcinoma, prostate, and colon carcinoma cell lines. In the acute toxicity tests, rats received oral doses of BEE as 1000, 2000, and 3000 mg/kg body weight. Mortality, signs of toxicity, body weight, food consumption, and gross findings were observed for 14 days. Blood samples were collected from anesthetized animals and used for hematological and biochemical parameters. Histopathological study was performed using liver and kidney samples. Results: The BEE does not show significant cytotoxic effect against the tested cell lines up to the range from 5 to 320 \μg/ml. In acute toxicity study, also lethality was not observed up to 3000 mg/kg b.w. No significant differences were noticed in body and organ weights and histopathology examinations between the control and treated groups. Conclusion: This study authenticates stem BEE may contain bioactive compounds of potential therapeutic significance which are relatively safe from toxic effects, and evidences the medicinal use of this plant in folk medicine.
