ABSTRACT
The HPTLC analysis, antioxidant. and antigout activity of Asparagus racemosus, Withania somnifera, Vitex negundo, Plumbago leylanica, Bute a monosperma and Tephrosia pur pure a extracts were investigated. The chemical fingerprinting were carried out by high performance thin layer chromatography [HPTLC]. antioxidant activity by ABTS, DPPH. FRAP radical scavenging assays, and antiogout activity by cow milk xanthine oxidase. The HPTLC fingerprint qualitatively revealed predominant amount of flavonoids. The TEAC values ranged from 45.80 to 140 microM trolox/100 g dry weight for ABTS, from 85 to 430 microM trolox/ 100 g dw DPPH, and 185 to 560 microM trolox/100 g dw for FRAP respectively. Plants used in this study was found to inhibit the toxicity. as seen from the decreased LPO and increased GSH. SOD and CAT levels. The total phenolic and flavonoid content ranged from 10.21 to 28.17 and 5.80 to 10.1 mg of gallic acid equivalents [GAE]/100 gdw respectively. The plant extracts demonstrated significant xanthine oxidase inhibitory activity at 100 g/mL and revealed an inhibition greater than 50% and IC-[50] values below the standard. This effect was almost similar to the activity of allopurinol [Standard drug] against xanthine oxidase [90.2 + 0.4%]. These plant root extract will be subjected for further extensive studies to isolate and identify their active constituents which are useful for against inflammation and gout
