牻牛兒苗科植物Geranium屬及Erodium屬之地上部做為止瀉整腸劑,有效成分為單寧類之Geraniin。麝香牻牛兒苗(E. moschatum)為在台灣新發現之馴化種。麝香牻牛兒苗之含水丙酮萃取物,利用逆相層析膠質,分離到十七種單寧及相關化合物,包括五種phenolcarboxylic acid及酯類:protocatechuic acid (1), gallic acid (2), methyl gallate (3), caffeic acid(4), brevifolincarboxylic acid (5); 四種 gallotannins:3-O-galloylshikimic acid (6), 3,4-di-O-galloylshikimic acid (7), 3,5-di-O-galloylshikimic acid (8), 1-O-galloyl-b-D-glucose (9); 六種 ellagitannins及相關化合物: corilagin (10), furosin (11), geraniin (12), acetonylgeraniin A (13), methyl gallate 3-O-b-D-glucoside (14), gallic acid 3-O-b-D-(6'-O-galloyl)-glucoside (15)及二種flavonoids: kaempferol (16), quercetin (17)。化合物結構係依其物理性質及核磁共振光譜而決定,並與文獻或標準品比對確認。" |
英文摘要 |
Erodium moschatum is a newly naturalized plant in Taiwan. From the aqueous acetone extract of the fresh herb, seventeen tannins and related compounds were isolated. They included five phenolcarboxylic acids and ester including: protocatechuic acid (1), gallic acid (2), methyl gallate (3), caffeic acid (4), brevifolincarboxylic acid (5); four gallotannins: 3-O- galloylshikimic acid (6), 3,4-di-O-galloylshikimic acid (7), 3,5-di-O-galloylshikimic acid (8), 1-O-galloyl-β-D-glucose (9); six ellagitannins and other related compounds which include corilagin (10), furosin (11), geraniin (12), acetonylgeraniin A (13), methyl gallate 3-O-β-D-glucoside (14), gallic acid 3-O-β-D-(6'-O-galloyl)-glucoside (15) and two flavonoids: kaempferol (16), quercetin (17). These structures were identified on the basis of their physical data and spectroscopic evidence.
