Chlorogenin

Title: Chlorogenin
CAS Registry Number: 562-34-5
CAS Name: (3b,5a,6a,25R)-Spirostan-3,6-diol
Molecular Formula: C27H44O4
Molecular Weight: 432.64
Percent Composition: C 74.96%, H 10.25%, O 14.79%
Literature References: Isoln from bulbs of the California soap plant, amole: Chlorogalum pomeridianum (DC.) Kunth, Liliaceae: Liang, Noller, J. Am. Chem. Soc. 57, 525 (1935). Chlorogenin occurs in amole as a saponin which kills or stuns fish without rendering them inedible. Structure: Marker, Rohrmann, ibid. 61, 947, 3479 (1939); Marker et al., ibid. 62, 2537, 3006 (1940). On hydrogenation the 3b,6b-isomer (b-chlorogenin) is produced.
