Calculate Digit Verification of CAS Registry Number 129744-09:
(8*1)+(7*2)+(6*9)+(5*7)+(4*4)+(3*4)+(2*0)+(1*9)=148
148 % 10 = 8

STEROIDAL SAPONINS FROM THE BULBS OF LILIUM BROWNII

Mimaki, Yoshihiro,Sashida, Yutaka

, p. 2267 - 2271 (1990)

The methanol extract of the fresh bulbs of Lilium brownii has yielded a 27-acyloxyspirostanol saponin, named brownioside and a furospirostanol saponin, which appear to be new constituents.The respective structures have been shown by the spectroscopic evidence and alkaline- and acid-catalysed degradations to be (25R)-27-O-(3-hydroxy-3-methylglutaroyl)-spirost-5-en-3β,27-diol 3-O-2)>-β-D-glucopyranoside and (22S,25S)-26-O-β-D-glucopyranosyl-22,25-epoxyfurost-5-en-3β,26-diol 3-O2)>-β-D-glucopyranoside.Several known phenolic compounds have also been isolated and identified.
