Clinoposide A-1, C30H48O4, Mr = 472. 71, monoclinic, P21, a = 12. 952(4), b = 6.674(5), c=15. 084(6)(?) , β= 101. 94(3)°, V= 1276(1)(?)3. Z = 2, Dc=1. 23g/cm3, μ(Mo-Ka) = 0. 74cm-1, F (000)= 520. The structure was solved by direct methods and refined to a final R = 0. 056 using 1468 observed reflections with I> 3*(I). The molecule was revealed as a compound of pentacyclic-triter-pene with tetrahydroxyl groups.
