| 英文摘要: | This dissertation dealt with the chemistry of the natural resources of five medicinal plants, Porana discifera Schneid (Convolvulaceae), Porana spectabilis Kurz (Convolvulaceae), Winchia calophylla A. DC. (Apocynaceae), Elsholtiza bodinieri Van (Labiatae) and Pofyalthia cheliensis Hu (Anno-naceae). From above five plants, 91 compounds including p-sitosterol and daucosterol were isolated. By spectroscopic and chemical methods, their structures were identified as ecdysterone (1), ecdysterone-2-acetate (2), ecdysterone-3-acetate (3), ecdysterone-25-acetate (4), 2,3-isopropilidene ecdysterone (5), 20,22-isopropilidene ecdysterone (6), 2-deoxyecdysterone (7), 20,22-isopropilidene 2-deoxyecdysterone (8), 2-deoxyecdysterone-3-(9-f}-D-glucopyranoside (9), 2-deoxyecdysterone-25-0-P-D-glucopyranoside (10), posterone (11), disciferatriol (12), disciferoside A (13), (4R)-menthane-lS,2S,8-triol (14), lp,2(3,3a, 4(3,5a-cyclohexanepentol (15), dodecandral-3-0-p-D-xylopyranoside (16), D-galactitol (17), E-piceid (18), scopoletin (19), scoplin (20), ethyl caffeate (21), (3,5-dihydroxphenyl)-2￡'-propenoic acid (22), methyl a-D-frucofuranoside (23), methyl p-D-frucopyranoside (24), 2,5-dihydroxybenzoic acid (25), 2,5-dihydroxybenzaldehyde (26), (+)-syringare-sinol-4-O-p-D-glucopyranoside (27), 3P-hydroxy-27-(4-hydroxy-3-methoxy-JE -cinnamoyloxy)-lup-20(29)-en-28-oic acid (28), lupenone (29), lupenyl acetate (30), betulinic acid (31), cc-amyrin acetate (32), ursolic acid (33), ptiloepoxide (34) and P-amyrin (35), cycloeucalenol (36), sweroside (37), butyl winchioside (38), butyl isowinchioside (39), ethyl winchioside (40), 7-formyl loganin (41), 6 -formyl loganin (42), 7,6'-diformyl loganin (43), loganin (44), loganic acid (45), winepoxide (46), wincaloside A (47), wincaloside B (48), butyl-p-D-glucopyranoside (49), butyl-a-D-grucopyrano-side (50), butyl-P-D-galatofuranoside (51), echitamidine (52), alstoqustine (53), N(4)-methyl akuammicine (54), 19,20-diepf echitamidine (55), tubota- wine (56), rhazimanine (57), echitamine (58), 17-Oacetyl echitamine (59), pseudoakuammigine (60), picrinine (61), nareline (62), stemmadenine (63), vallesamine (64), cantleyine (65), isocantleyine (66), venoterpine (67), rutaecarpine (68), eyodiamine (69), dehydroevodiamine hydrochloride(70), 1,2,3,4-tetrahydro-l-oxo-p-carboline (71), l-methyl-2-[(102)-10-pentadecan-enyl]-4(lH)-quinolone (72), paeonol (73), 4-hydroxy-3-methoxybenzoic acid (74), 3,4-dihydroxybenzoic acid (75), 2,3-dihydroxybenzoic acid (76), sesa-min (77), (-)-lyoniresinol (78), hederagenin-3-O-P-D-xylopyranoside (79), 2,23-hederagenin-D-xylose acetal or (2,23-hederagenin)-mercaptal-D-xylose (80), dodecandral-3-<9-P-D-xylopyranoside (16), 3p,23-dihydroxyolean-12-en-28-oic acid (81), rosmarinic acid (82), 5,7,3',4'-tetrahydroxyfiavanone (83), 5,3',4'-trihydroxy-7-<3-P-D-glucopyranosylflavanone (84), 5,3',4'-trihydroxy-7-O-P-D-glucopyranosylflavone (85), 3",3'"-bispolycerasoidol (86), la-acetoxyl ent-jxmenol or 6p-hydroxy-(5p,7a,10a)-eudesma-4(15)-en-la-yl acetate (87), polycerasoidol (88), isopolycerasoidol (89), which the compounds 12,13,16, 28, 38-43, 46-48, 51, 79, 80, 86 and 87 were the new ones. In the determinations of the structures of compounds 12 and 13, the configurations of some positions of 11 compounds in the 7 literatures were revised by literature investigation, spectroscopic, chemical and X-ray diffraction methods. |
