Studies on the Chemical Constituents of Malay Licorice (Glycyrrhiza yunnanensis) / 中草药

Six compounds were isolated from Glycyrrhiza yunnattettsis. on the basis of physico-chemical properties and spectroscopic analysis, their structures were identified as homopterocarpiu (Ⅰ ), medicarpin (Ⅱ ), formononetin (Ⅲ ), 4' -methoxy-4-hydroxy challone (Ⅳ ), glyyunnansapogeuin B (Ⅴ ) and ?-sitosterol (Ⅵ ). Ⅰ~Ⅴ are fouud for the first time in this species,
