The volatile oil obtained from the cones of Cupressus funebris  by hydrodistillation was subjected to anti-inflammatory activity using carrageenan induced paw oedema model using albino mice, Diclofenac sodium was used as standard drug (25 mg/kg body weight, p.o.). The volatile oil (100 mg/kg body weight, p.o.) showed significant anti inflammatory activity.

Antimicrobial activity of chloroform and methanolic extracts of Salacia reticulata  were tested against gram positive, gram negative and fungus strains using zone of inhibition and minimum inhibitory concentrations. It was observed that both extracts have inhibitory effect towards all microorganisms used in the test. Chloroform extract was more effective than methanolic extract.

Insight of evidence that some complications of diabetes mellitus due to hyperglycemia, we investigated the effect of T.arjuna  bark extract on serum, liver and kidney marker enzymes in alloxan - induced diabetic rats. T. arjuna  was administered orally at a doses of 250 and 500 mg/kg body weight for 30 days, after which serum liver and kidney tissues were assayed for the degree of pathological changes by means of markers such as alkaline phosphatase (ALP), acid phosphatase (ACP), alanine amino transferase (ALT), aspartate amino transferase (AST) and lactate dehydrogenase (LDH) resulted in a significant reduction in serum and tissue of liver and kidney marker enzymes when compared with control rats T. arjuna  at a dose of 500 mg/kg body weight exhibited higher efficacy.

In the present investigation, aqueous, ethanol and petroleum ether, ethanol (1:1) root extracts of Seidenfia rheedii  were tested against 12 different human pathogenic bacteria for antibacterial activity. It was found that ethanolic extracts inhibited the growth of all the bacterial strains tested whereas moderate antibacterial activity was associated with petroleum ether, ethanol (1:1) root extracts. The aqueous extract did not show antibacterial activity. Thus the present investigation reveals that the selected plant extracts have potential of bactericidal effect on test bacteria.

The present paper represents the results of an ethnobotanical survey conducted in Mundakunnu village of Gudalur taluk, Nilgiri district of Tamil Nadu, India. It has been observed that the plant species are used to various ailments of analgesic, antidiarrhoeal, piles, antidiabetic, gynecological problems, vermifuge, antidandruff, venereal diseases, bone fracture and as vegetables. A total of 52 plants species belonging to 51 genera (33 dicot & 6 monocot) have been discussed.

A polyherbal formulation was evaluated for its hepatoprotective activity against ethanol and CCl ₄  induced liver damage in rats. The rats were divided into five groups of six animals each and serve as control, toxic, post-treated, herbal control, Liv.52 treated groups respectively. The results showed that the activities of liver marker enzymes in serum namely AST, ALT, ALP, ACP and serum bilirubin level (total) were increased in toxic group animals. But the activities of these enzymes were significantly lowered in post-treated group of rats. Thus, the results suggest antihepatotoxicity of "Ayush-Liv.04".

The macroscopic character of the whole plant, physical constant values, extractive values, behaviour on treatment with different chemical reagents. Fluorescence characters under uv light after treatment with different chemical reagents of the powdered whole plant of lonidium suffruticosam  Ging (Family; violaceae) were studied to characterize some pharmacognostical parameters. Preliminary photochemical study on different extracts of the whole plant were also performed.

Phytochemical studies of whole plant of Phyllanthus debilis  Klein.ex.willd (Euphorbiaceae) reveals the presence of phytosterols, lignans, glycosides and absence of saponin, triterpenoids, tannins and alkaloids have been reported in this plant for the first time.
