title: Alkaloids from Heimia salicifolia.
abstract: Two alkaloids, 9beta,2'-dihydroxy-4'',5''-dimethoxy-lythran-12-one or 9beta-hydroxyvertine (1) and (2S,4S,10R)-4-(3-hydroxy-4-methoxyphenyl)-quinolizidin-2-acetate (2), as well as seven known alkaloids, lythrine (3), dehydrodecodine (4), lythridine (5), vertine (6), heimidine (7), lyfoline (8) and epi-lyfoline (9), were isolated from Heimia salicifolia. The structures of these compounds were elucidated by extensive spectroscopic techniques. Furthermore, the structures of 2, 3, and 6 were confirmed by X-ray crystallography, including absolute configuration determination of 2 and 6. Compounds 6 and 9 showed moderate antimalarial activity.
