Ali, M.,Bhutani, K. K.,Srivastava, T. N.
, p. 3601 - 3604 (1990)
Three new triterpenes have been isolated from the stem bark of Symplocos racemosa together with the two known triterpenoids betulin and oleanolic acid.Their structures were characterized as 28-hydroxy-20α-urs-12,18(19)-dien-3β-yl acetate, 3-oxo-urs-20α-12,18(19)-dien-28-oic acid and 24-hydroxyolean-12-en-3-one by spectral and chemical means.

, p. 783 - 786 (1987)
A novel taraxerane-type triterpene-diol, in addition to taraxerol and lupeol, was isolated from the leaves of Parsonsia laevigata.Its structure was shown to be (4β)-D-friedoolean-14-ene-3β,24-diol (taraxer-14-ene-3β,24-diol) by a combination of chemical and spectroscopic methods.Key Word Index - Parsonsia laevigata; Apocynaceae; taraxerane-type triterpenoid; (4β)-D-friedoolean-14-ene-3β,24-diol.
Triterpenoid derivatives from Cylicodiscus gabunensis
Mkounga, Pierre,Tiabou, Alembert Tchinda,Kouam, Jacques
experimental part, p. 1100 - 1102 (2010/11/16)
Three new olean-12-ene derivatives (1-3), together with known urs-12-ene-3β, 28-diol (4) were isolated from the stem root of Cylicodiscus gabunensis. The structures of the new compounds were established by chemical and spectroscopic means as β-amyrin-n-no
