title: [Study on the constituents from freeze-dried power of blackberries (Rubus ursinus)].
abstract: Three Compounds were isolated from freeze-dried powder of Blackberries (Rubus ursinus L.) which showed an activity on inhibition of chemocarcinogen. The structures of them were identified as stigmasta-5,22-dien-3-ol],beta-sitosterol and beta-sitosterol-3 beta-D-glucose. All these compounds were isolated at the first time from the plant.
