Six coumarins, four furoquinoline alkaloids, one glycosylflavonoid, two triterpenes, and one steroid have been characterized from stems, leaves and fruit of Zanthoxylum rhoifolium Lam. var. petiolulatum Engler (Fagara rhoifolium), of which one furoquinoline alkaloid is a new compound. The composition is very different from other reported studies of Z. rhoifolium. The structures of the compounds isolated were determined by spectroscopic methods. © 1992.
