Kaurane and kaurene diterpenes from the stem bark of Xylopia acutiflora

Phytochemistry, 1982
Abstract Four diterpenes were isolated from the stem bark of Xylopia acutiflora and characterized as (−)-kauran-16α-ol, 7,8-acetoxy-(−)-kaur-16-en-19-oic acid, 15-oxo-(−)-kaur-16-en-19-oic acid, and 16α- hydroxy-(−)-kauran-19-oic acid.

Structural Studies of Kaurane Diterpenes From Ryparosa acuminata (Flacourtiaceae)

Australian Journal of Chemistry, 1993
Two new diterpenes have been isolated from the twigs of Ryparosa acuminata ( Flacourtiaceae ), and identified as 16a,19-dihydroxykauran-20-oic acid d- lactone and 16a-hydroxykaurane-19,20-dial. Friedelin and eudesmin were also isolated. The structure of the lactone was confirmed by X-ray crystallography.
