Abstract
We have isolated for the first time the native aglycone of a triterpene glycoside of the holoturin series — holothurin B1 — and have established its structure as holost-9-ene-3β,12α,17α-triol. The structures of two new holostane derivatives have been established — holosta-8,11-diene-3β,17α-diol and 3β,17α-dihydroxyholost-9-en-12-one. A scheme of transformation of the native genin of holothurin B1 under the conditions of the acid splitting of the glycoside has been put forward.
