Indolopyridoquinazoline alkaloid from Leptothyrsa sprucei

Phytochemistry. 2001 Oct;58(4):627-9. doi: 10.1016/s0031-9422(01)00248-5.

Abstract

The indolopyridoquinazoline alkaloid, 3-hydoxyrutaecarpine, was isolated from Leptothyrsa sprucei, along with 8-methoxypsoralen, 5-methoxypsoralen, imperatorin, isoimperatorin, kaempferol 3-O-alpha-L-rhamnopyranoside, clematine and cnidioside B. The usefulness of the gradient 1H-15N HMBC NMR spectroscopy in the structure elucidation of 3-hydroxyrutaecarpine is noted.
