title: Phytoecdysteroids of Diploclisia glaucescens Seed.
abstract: Five phytoecdysteroids were isolated from the seeds of DIPLOCLISIA GLAUCESCENS and identified by spectrometric methods ( (1)H-NMR, (13)C-NMR and CIMS). One of them, 24- EPI- makisterone A, has not been reported before. The other four - 20-hydroxyecdysone, makisterone A, 24(28)-dehydromakisterone A and pterosterone - were known previously. The (13)C-NMR spectrum of 24(28)-dehydromakisterone A is presented for the first time.
