In vitro studies on antilithiatic activity of seeds of Dolichos biflorus Linn. and rhizomes of Bergenia ligulata Wall.

Soxhlet extracts of seeds of Dolichos biflorus and rhizomes of Bergenia ligulata were tested for their in vitro antilithiatic/anticalcification activity by the homogeneous precipitation method. The extracts were compared with an aqueous extract of cystone (a marketed preparation) for their activities. Also a combination of the extracts of the two plants was tested. Extracts of Dolichus biflorus showed activity almost equivalent to cystone while Bergenia ligulata showed less activity and the combination was not as active as the individual extracts.
