Isoschaftosid 是从DeSmodium uncinatum根部分泌物中提取的 c- 糖基黄酮类天然产物，有抗肿瘤、抗氧化和抗菌活性，它还对 M. incognita 具有很强的杀线虫活性。

Isoschaftoside is used as an intercrop due to its allelopathic inhibition of parasitism by Striga hermonthica, an obligate parasitic weed that can devastate the maize crop. Isoschaftoside has anti-tumor, antioxidant, and antimicrobial activities, it also possesses strong nematicidal activity against M. incognita.

METHODS AND RESULTS:In East African small-holder farming of maize, the cattle forage legume, Desmodium uncinatum is used as an intercrop due to its allelopathic inhibition of parasitism by Striga hermonthica, an obligate parasitic weed that can devastate the maize crop. Bioassay-guided fractionation of the root extract of D. uncinatum revealed Isoschaftoside to be the main compound in the most potent fraction inhibiting growth of germinated S. hermonthica radicles. Bioassays repeated with Isoschaftoside isolated from a different plant source, Passiflora incarnata, proved it to be a biologically active component. CONCLUSIONS: Analysis of the root exudates produced by hydroponically grown D. uncinatum showed Isoschaftoside to be present in the hydroponic media at biologically active concentrations of 10-100 nM.
