The Chemical Constituents of Australian Zanthoxylum Species. VI. A Further Examination of the Constituents of the Bark of Zanthoxylum conspersipunctatum (Rutaceae)

Abstract

From the bark of Zanthoxylum conspersipunctatum Merr. & Perry the following substances were isolated: chelerythrine and sanguinarine chlorides, 13-acetonyldi-hydrochelerythrine, β-sitosterol, lupeol, lupenone, sesamin, hesperidin, tembamide, O-methyltembamide, cyclotriveratrylene, and psoromic acid. O-Methyltembamide is almost certainly an artefact, as is cyclotriveratrylene, and psoromic acid probably originated from a lichen on the bark.
