Abstract

The alkaloids pellitorine and chelerythrine acetonate were isolated from the stem bark of Zanthoxylum davyi together with methyl octadecyl ketone, lupeol and hesperidin. The alkaloid skimmianie was isolated from the leaves. The X-Ray structure of chelerythrine acetonate was also determined.

Key Words: Zanthoxylum davyi; Rutaceae, chelerythrine acetonate; methyl octadecyl ketone; lupeol; skimmianine; hesperidin; X-Ray structure; 13CNMR; NOE; HMBC.
