Steroid sponins and flavonoids of leavs of Phoenix rupicola T. ANDERSON, P. loureirii KUNTH, P. reclinate N. J. JACQUIN, and Arecastrum romanzoffianum BECCARI have been investigated. Tricin 7-O, β-D-glucopyranoside (I), vitexin (II), methyl proto-Pb (VII), methyl proto-taccaoside (26- O, β-D-glucopyranosyl (25R)-22-O-methyl-furost-5-en-3β, 26-diol 3-O-[α-L-rhamnopyranosyl-(1→2)][α-L-rhamnopyranosyl-(1→3)]-β-D-glucopyranoside, VI), and methyl proto-rupicolaside (26-O, β-D-glucopyranosyl (25R)-22-O-methy-furost-5-en-3β, 26-diol 3-O-[β-D-glucopyranosyl-(1→2)-α-L-rhamnopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→4)][α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside, VIII) from P. rupicola, II, glucoluteolin (III), orientin (IV), isoorientin (V), VII, VIII, and methyl proto-loureiroside (26-O-β-D-glucopyranosyl (25R)-22-O-methyl-furost-5-en-3β, 26-diol 3-O-[β-D-glucopyranosyl-(1→5)-α-L-arabinofu-ranosyl-(1→4)][α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside, IX) from P.loureirii, VII, VIII and methyl proto-reclinatoside (26-O-β-D-glucopyranosyl (25R)-22-O-methyl-furost-5-en-3β, 26-diol 3-O-[α-L-rhamnopyranosyl-(1→5)-α-L-arabinofuranosyl-(1→4)][α-L-rhamnopyranosyl(1→2)]-β-D-glucopyranoside, X) from P. reclinata, III and VII from A. romanzoffianum were isolated are identified. VI, VIII, IX and X were the first isolated and characterized from natural sources.
对 Phoenix rupicola T. ANDERSON、P. loureirii KUNTH、P. reclinate N. J. JACQUIN 和 Arecastrum romanzoffianum BECCARI 的叶子中的类固醇海绵苷和类黄酮进行了研究。三尖杉苷 7-O、β-D-吡喃葡萄糖苷(I)、牡荆苷(II)、甲基原-Pb(VII)、甲基原-Taccaoside(26-O、β-D-吡喃葡萄糖苷(25R)-22-O-甲基-呋喃甾-5-烯-3β,26-二醇 3-O-[α-L-吡喃鼠李糖基-(1→2)][α-L-吡喃鼠李糖基-(1→3)]-β-D-吡喃葡萄糖苷,VI)、和甲基原呋喃核苷(26-O,β-D-吡喃葡萄糖基(25R)-22-O-甲基呋喃甾-5-烯-3β、26-二醇 3-O-[β-D-吡喃葡萄糖基-(1→2)-α-L-吡喃鼠李糖基-(1→4)-α-L-吡喃鼠李糖基-(1→4)][α-L-吡喃鼠李糖基-(1→2)]-β-D-吡喃葡萄糖苷,VIII)。(1→4)[α-L-rhamopyranosyl-(1→2)]-β-D-吡喃葡萄糖苷,Ⅷ)、葡肉豆蔻苷(III)、荭草苷(IV)、异荭草苷(V)、Ⅶ、Ⅷ,以及甲基原牛磺酸苷(26-O-β-D-吡喃葡萄糖基 (25R)-22-O-甲基-呋喃甾-5-烯-3β、26-diol 3-O-[β-D-吡喃葡萄糖基-(1→5)-α-L-阿拉伯呋喃糖基-(1→4)][α-L-鼠李糖基-(1→2)]-β-D-吡喃葡萄糖苷,IX) from P.Loureirii、VII、VIII 和来自 P. Rclinata、III 和 VIII 的甲基原 reclinatoside(26-O-β-D-吡喃葡萄糖基 (25R)-22-O-甲基-呋喃甾-5-烯-3β,26-二醇 3-O-[α-L-吡喃鼠李糖基-(1→5)-α-L-阿拉伯呋喃糖基-(1→4)][α-L-吡喃鼠李糖基-(1→2)]-β-D-吡喃葡萄糖苷,X)。从 P. reclinata 和 A. romanzoffianum 中分别分离出 III 和 VII。VI、VIII、IX 和 X 是首次从天然来源中分离和鉴定的。
