Abstract:
A new 4.5-dioxoaporphine alkaloid, 8-methoxyyouregidione, along with artabotrine, ouregidione, liriodenine, oxocrebanine, oxobuxifoline, atherospermidine and lanuginosine have been isolated from Artobotrys zeylanicus. Investigation of Xylopia championii afforded O-methylmoschatoline and dicentrinone.

PMID: 11324918;Abstract:
Two benzophenanthrene alkaloids, 8-acetonyldihydronitidine and 8-acetonyldihydroavicine were isolated from Zanthoxylum tetraspermum stem bark along with liriodenine, sesamin, lichexanthone and (+)-piperitol-γ,γ-dimethylallylether. The-species endemic to Sri Lanka, Z. caudatum, contained sesamin, savinin, liriodenine, decarine and 8-O-desmethyl-N-nornitidine. 8-Acetonyldihydronitidine and 8-acetonyldihydroavicine showed significant antibacterial activity while the former along with liriodenine was strongly antifungal. Savinin exhibited potent spermicidal activity. Both savinin and sesamin exhibited significant insecticidal activity. © 2001 Published by Elsevier Science Ltd.

Taxol [1] can be separated from the closely related co-occurring diterpenoid cephalomannine [2] by oxidation of a mixture of the two with OsO4 and flash chromatography of the resulting products.
