1.  Physico-Phytochemical investigation and Anti-inflammatory screening of Capsicum annum L. and Hemidesmus indicus (Linn.) R. Br 
Ancient Science of Life  2010;29(4):35-40.
Capsicum annum L. (Family: Solanaceae) and Hemidesmus indicus (Linn.) R.Br. (Family: Asclepiadaceae) are commonly used in Tamilnadufor treating various ailments in the native system of medicine. The hydroalcoholic extracts of both plants at dose level of 100 mg/kg body weight showed demonstrable anti-inflammatory activity in the carrageenan-induced hind paw model in rats. Nevertheless, the overall anti-inflammatory activity exhibited by the extracts are found to be less as compared with that of standard drug Indometacin. Preliminary physico-phytochemical analysis of the plants in question were attempted. The results are highlighted and discussed.

2.  Antioxidant potential of Lactuca sativa 
Ancient Science of Life  2004;24(1):6-10.
The present study is based on the evaluation of antioxidant potential of a well known plant Lactuca sativa. Methanolic leaf extract was investigated for in vitro inhibition of oxidative damage induced by UV-radiations to the salmonella typhi bacteria and in vivo effect on the production of body enzymes i.e. catalase and superoxide dismutase. The lipid peroxidation masurement was also done in terms of thiobarbituric acid reactive substances (TBARS) in blood and brain of male albino wistar rats. The plant extract has shown significant antioxidant potential both in vitro and in vivo.

4.  COMPARATIVE MICROBIOLOGICAL ACTIVITIES OF ETHANOLIC EXTRACTS OF ROOTS AND AERIAL PARTS OF ACHYRANTHES ASPERA LINN 
Ancient Science of Life  2003;22(4):140-145.
Ethanolic extract of roots and aerial parts of Achyranthes aspera was investigated for its antibacterial activity against Bacillus subtilis, Bacillus pumilus, and Proteus vulgaris and anti fungal activity against Cryptococcus neoformans, Aspergillus flavus at 100 mg/disc using diffusion method. The comparative studies shown that ethanolic extract of roots and aerial parts of Achyranthes aspera have exhibited moderately equal action when compared to Cotrimoxazole (30 mg/disc) for antibacterial and Clotrimazole (30 mg/disc) for antifungal activity. Our findings confirm the traditional therapeutic claims for this herb.

5.  Studies on some Pharmacognostical profiles of Leucas lavandulaefolia Rees. (Family Labiatae) 
Ancient Science of Life  2000;19(3-4):96-101.
The macroscopic characters of L. lavandulaefolia, physical constant values, behaviour on treatment with different chemical reagents, fluorescence characteristics after treatment with different chemical reagents of the powder of L. Lavandulaefolia were studied to fix some pharmacognostical parameters. Preliminary phytochemical studies and TLC characterization of different extractives has also been performed. These studies will help in future for identifying the plant for further research.

7.  PHYSICAL CHARACTERIZATION OF THE TINCTURES OF FICUS RACEMOSA L. 
Ancient Science of Life  1997;16(3):196-199.
Tinctures of Ficus racemosa Linn leaves were prepared by maceration process. 70% alcohol of 21 days maceration showed maximum total solid 2.07% deep greenish brown colour and of 7.1 pH.

8.  PHYSICO –CHEMICAL CHARACTERISTICS OF TINCTURE FROM ASPARAGUS RACEMOSUS WILLD 
Ancient Science of Life  1996;16(2):160-165.
Various strength of alcohol were utilized for the preparation of tincture of asparagus racemosus roots by maceration for 7, 14 and 21 days. 50% (V/V) alcohol after 21 days of maceration showed maximum yield of total solid. The tinctures were evaluated by studying their different physico-chemical characteristics along with thin-Layer chromatography.
