Three New Triterpenoid Saponins from Notoginseng Medicinal Fungal Substance

Three new triterpenoid saponins, named ginsenoside‐Rh 23 ( 1 ), ginsenoside‐Rh 24 ( 2 ), and ginsenoside‐Rh 25 ( 3 ), were isolated from notoginseng medicinal fungal substance. Their structures were elucidated by a combination of 1D‐ and 2D‐NMR, MS and chemical analysis. Compounds 1 – 3 exhibited moderate cytotoxic activity against MCF‐7 and NCI‐H460 cancer cell lines.
