RESUMO
Phenylpropanoids are one of the major chemical constituents in Zanthoxylum species. They include simple phenylpropanoids, coumarins, and lignans and possess anti-tumor, anti-inflammatory, anti-platelet aggregation, anti-bacterial, anti-viral, insecticidal, and antifeedant activities. This review summarizes the chemical constituents and pharmacological activities from the Zanthoxylum plants in hopes of providing reference for the research and application of phenylpropanoids from this genus.

Four new triterpene saponins, mandshunosides F-I (1-4), together with five known compounds (5-9), were isolated from the roots and rhizomes of Clematis mandshurica. Their structures were elucidated on the basis of spectroscopic evidences and hydrolysis products. Bisdesmosidic saponin (3-9) showed modest suppression of NO production with the inhibition ratios in the range of 51.3%- 64.6% at 50 μmol·L, whereas monodesmosidic saponins with a free carboxyl group at C-28 (1 and 2) showed potent inhibitory activities with IC values being 12.7 and 8.3 μmol·L, respectively.

There are 250 species of Zanthoxylum (Rutaceae) in the world. This genus distributed in tropical and subtropical regions. Alkaloids are the major and representative ingredients in these plants including quinolines, isoquinolines, and amide alkaloids, with such biological activities as anti-tumor, anti-inflammatory, analgesic, anti-virus, anti-platelet aggregation, anti-bacteria and anti- oxidant. These species have been used for a long time to treat toothache, urinary and venereal diseases, lumbago and rheumatism. This review summarizes the chemical constituents and pharmacological activities from the Z. sppplants, in an effort to the systematic research and application of the alkaloids of this genus.
