title: Glycosides of 14,15-seco- and 13,14:14,15-disecopregnanes from the roots of Tylophora tanakae.
abstract: Five new glycosides of 14,15-seco- and 13,14:15-diseco-type pregnanes, including a new pregnane, 2 alpha-hydroxyhirundigenin, were isolated, in addition to one known glycoside, cynatratoside B, from the roots of Tylophora tanakae Maxim. Their structures were elucidated by spectral and chemical means.
