Abstract
Forty-seven components were isolated from the following four mushrooms and two medicinal plants in Taiwan : Hericium erinaceum (BULL. ex. FR.) PERS.; Pholiota aurivella (BATSCH : FRES) KUMMER; Amauroderma rugosum (BL. & NEES) TORREND; Poris cocos (SCHW.) WOLF. with the roots of Pinus sp.; Koelreuteria henryi DUMMER and Lactuca sororia MIQ.. The structures of these compounds were elucidated on the basis of spectral data and chemical evidence as shown below:1. Hericium erinaceum (BULL. ex. FR.) PERS.mixture of fatty acid esters (HE-1), mixture of fatty acids (HE-2), 4-methoxybenzoic acid (HE-3), (22E)-ergosta-5,7,22-trien- 3b-ol (HE-4), (22E)-5,8-epidioxyergosta-6,22-dien-3b-ol (HE-5), hericenone D (HE-6), hericenone H (HE-7), ceramides (HE-8), erinapyrone C (HE-9), erinapyrone D (HE-10).2. Pholiota aurivella (BATSCH：FRES) KUMMER(22E)-ergosta-4,6,8,22-tetraen-3-one (PA-1), (22E)-ergosta-7,22-dien- 3b-ol (PA-2), (22E)-ergosta-22-en-3b-ol (PA-3), cerebrosides (PA-4), methyl 4-hydroxy-trans-cinnamate (PA-5), 4-methyl-trans-cinnamic acid (PA-6), methyl 4-hydroxybenzoate (PA-7), 4-hydroxy- benzaldehyde (PA-8), 4-hydroxybenzoic acid (PA-9), mixture of fatty acid methyl esters (PA-10).3. Amauroderma rugosum (BL. & NEES) TORRENDglycerides (AR-1), (22E)-ergosta-7,22-dien-3-one (AR-2), (22E)-ergosta-7,22-dien-3b-ol (AR-3), (22E)-ergosta-5,7,22-trien- 3b-ol (AR-4), (22E)-5,8-epidioxyergosta-6,22-dien-3b-ol (AR-5), cerebrosides (AR-6).4. Poris cocos (SCHW.) WOLF.with the roots of Pinus sp.dehydroabietic acid (PC-1), dehydrotumulosic acid (PC-2), 3b,16a- dihydroxyeburica-8,24(28)-dien-21-oic acid (PC-3), polyporenic acid (PC-4), pachymic acid (PC-5).5. Koelreuteria henryi DUMMERaustrobailignan-1(KH-1), methyl gallate (KH-2), gallic acid (KH-3), methyl (3,4,5-tri-O-galloyl)quinate (KH-4), 1,3,4,5-tetra-O-galloyl- quinic acid (KH-5), 3,4,5-tri-O-galloylquinic acid (KH-6).6. Lactuca sororia MIQ.germanicyl acetate (LS-1), lupeol (LS-2)、methyl 4-hydroxyphenylacetate (LS-3), vanillin (LS-4), 4-hydroxybenzoic acid (LS-5), 11b,13-dihydrosantamarin (LS-6), cichorioside B (LS-7), 11b,13-dihydrolactucin (LS-8), 9a-hydroxy-11,13a-dihydrozaluzanin C (LS-9), phytosteryl glycoside (LS-10).Erinapyrone C (HE-9) and erinapyrone D (HE-10) are novel, and methyl (3,4,5-tri-O-galloyl)quinate (KH-4) is obtained first time from natural source.
