Studies on the Constituents of the Higher Fungi in Korea(IV) -Isolation of Gultorin from Lactarius piperatus$(F_{R.})$ S.F. $G_{RAY}$-

한국산(韓國産) 고등균류(高等菌類)의 성분(成分) 연구(硏究)(IV) -Lactarius piperatus $(F_{R.})$ S.F. $G_{RAY}$로 부터 Gultorin의 분리(分離)-

In order to isolate constituents of Lactarius piperatus$(F_{R.})$ S.F. $G_{RAY}$, the fresh carpophore was homogenized with ethanol in a blendor, stored for three years and subsequently extracted with ethanol. From the concentrated ethanol solution, a mixture of compounds was precipitated, from which a white needle crystal, named 'gultorin', $(mp.160{\sim}162^{\circ})$ was obtained. The physical and chemical characteristics of gultorin were determined.
