サポニン生薬の研究 (第2報)

日本産敗醤の剖見と化学的成分に関する知見

抄録

Morphological studies were carried out on the underground portions of Patrinia scabiosaefolia Link and P. villosa Juss. From the difference of the two kinds thereby learned, the domestic crude drug Hai-shô, the root of Patrinia species, was confrimed as being derived from P. scabiosaefolia. A histochemical examination suggested the presence of a saponin in the root and rhizome of both kinds which showed hemolytic reaction. Saponin was isolated from the crude drug as colorless scaly crystals whose hydrolysis yielded sapogenin, glucose, arabinose, and xylose. The infrared absorption spectrum of the sapogenin agreed with that of oleanolic acid.
