Cetyl triacontanoate and other constituents from Acacia jacquemontii and Kigelia pinnata

摘要

Leaves of Acacia jacquemontii on chemical investigation afforded a new aliphatic ester-cetyl triacontanoate along with n-triacontanol, n-octacosanol, β-sitosterol and stigmasterol while the hcartwood of Kigelia pinnata gave lapachol, dehydro-α-lapachone, tccomaquincne-I, D-sesamin, paulownin, wodeshiol (kigeliol), kigelinone, β-sitosterol and stigmasterol on reinvestigation. The structures of isolated compounds were ascertained using various spectral (IR, ~1H, ~(13)C NMR, MS) techniques.
