摘要：

From leaves of Jaborosa leucotricha three new withanolides (20S,22R)-1,6 beta,17 alpha,27-tetrahydroxy-19-norwitha-1,3,5(10),24-tetraenolide, (20R,22R)-5 alpha,6 beta,14 beta,17 beta-tetrahydroxywitha-2,24-dienolide and (22R, 23S)-5 alpha,6 beta,17 beta-trihydroxy-12 beta-methoxy-12,22-epoxiergosta-2,24-dien-26,23-olide have been isolated and fully characterized by spectroscopic methods.
