dc.description.abstract Most of the phytoconstituents such as phenolics, glyco0sides, tannins, alkaloids, sterols and triterpenoids present in medicinal plants have natural anti-arthritic potential in human body. Enicostemma littorale Blume (EL) and Withania somnifera (L) Dunal (WS) are the local medicinal plants which have been widely used for treatment of arthritics conditions in Sri Lanka. Aim of this study was to compare the phytochemical constituents in different extracts and estimate quantitatively the active constituents related to anti-arthritic potential such as total phenolic, flavonoid, alkaloid, and saponin contents of these plants. The phytochemical screening of different (hot and cold ethanol, methanol and aqueous) extracts of both samples were estimated using the Folin-Ciocalteu and Aluminium-chlo0ride method respectively. Although the alkaloids, flavonoi9ds, steroids, tannins, coumarins, and phenols were high in all the extracts of each sample, the total phenolic and flavonoid contents in methanol extract of EL (44.4±1.3 mg GAE/g; 174.4±9.3 mg QE/g) were relatively higher than in methanol extract of WS (20.6±0.7 mg GAE/g; 7.2±0.9 mg QE/g). Higher content of total alkaloid compounds were found in the EL (2.3±0.01%w/w) when compared to the WS (0.8±0.01%w/w). It is noted that the anti-arthritic potential of EL was higher than WS. Further work should include the separation of active components and determination of anti-arthritic activities by recommended methods. en_US
