Two new isoflavone glycosides, millesianins F (1) and G (2), along with 11 known ones (3–13) have been isolated from then-butanol extract of the vine stems ofMillettia dielsianaHarms. The structures of1and2were established as cladrastin 7-O-β-d-apiofuranosyl-(1 → 6)-β-d-glucopyranoside (1) and fujikinetin 7-O-β-d-apiofuranosyl-(1 → 6)-β-d-glucopyranoside (2) by means of spectroscopic analysis and chemical methods. Some isolates (compounds1,3,4,5,6, and11) were tested for their effects on the proliferation of hematopoietic progenitor cell, and the preliminary results showed that all of investigated compounds had moderate activities but not in dose-dependent manners.
