[An experimental study(II) on the inhibition of prostatic hyperplasia by extract of seeds of Brassica alba].

Objective: To study the active components and their functionary mechanism of the extract of Brassica alba seeds, which inhibits experimental mice prostatic hyperplasia.

Method: Prostatic hyperplasia of castrated male mice induced by testosterone propionate, the penetrability of capillary vessel of mice skin induced by histamine and the endermic flesh bud of rat induced by filter paper were used as experimental models. Sinalbin and beta-sitosterol separated from seeds of Brassica alba were used to test the activities.

[An experimental study(I) on the inhibition of prostatic hyperplasia with extract of seeds of Brassica alba].

Objective: To study the effective fraction of the extract of seeds of Brassica alba, which inhibits experimental mice prostatic hyperplasia.

Method: An experimental model of prostatic hyperplasia of castrated male mice induced by testosterone propionate was made. Fractions I, II and III were prepared by extracting the seeds of Brassica alba successively with ether, ethanol and water under reflux.
