We investigated constituent of triterpenoid saponins ofAlbizzia, two new compounds together with two known compounds were isolated from Albizzia julibrissin Durazz. by using column chromatography (macroreticular resin, silica gel, Sephadex gel, reverse phase silica gel),preparative HPLC methods et al.On the basis of spectroscopic analysis, including IR,ESI-MS,~1H-NMR,~(13)C-NMR,HMBC,HMQC,~1H-~1HCOSY and chemical methods, the structure of two new compounds were identified as 3 - O -[β-D-xylopyranosyl(1→2)-β-D-fucopyranosyl (1→6)-β- D -2- deoxy - 2 - acetoamidoglucopyranosyl] -21-O-[(6S)-2- trans- 2,6-dimethyl - 6 - O-β- D - quinovopyranosyl -2,7- octadienoyl] - acacic acid- 28 - O-β-D-glucopyranosyl(1→3)[α-L-arabinofuranosyl(1→4)]-α-L-rhamnopyranosyl(1→2)-β-D-glucopyranoside acacic acid 3- O -β- D- glucopyranosy(1→3)-β- D- fucopyranosl(1→6) [β-D- xylopyranosyl (1→2)]-β-D-glucopyranoside ;two known compounds were acacic acid lactone 3- O -β-D- xylopyranosyl-(1→2)-β-D-fucopyranosl (1→6)- 2-deoxy -2 -acetoamido -β-D- glucopyranoside ; acacic acid lactone 3- O-β-D-xylopyranosyl(1→2)-α-L- arabinopyranosl (1→6)- 2- deoxy - 2- acetoamido -β-D-glucopyranoside . The study lays chemical foundation and chemical reference substance for enhancing quality standard of Albizzia julibrissin Durazz.
本研究论文在综述国内外对合欢属Albizzia三萜皂苷化学成分和药理作用研究进展的基础上,利用传统植化分离手段和现代分离技术,包括大孔树脂、硅胶、葡聚糖凝胶、反相硅胶等柱色谱,制备高效液相色谱法等技术从中药合欢皮中分离得到了4个化合物,其中,2个新化合物和2个己知化合物,并进一步通过现代分析技术IR,ESI-MS,~1H-NMR,~(13C-NMR,HMBC,HMQC,~1H-~1HCOSY等和化学方法鉴定了2个新化合物的结构分别是:3-O-[β-D-吡喃木糖基(1→2)-β-D-吡喃夫糖基(1→6)-β-D-2-去氧-2-乙酰氨基吡喃葡萄糖基]-21-O-[(6S)-2-反式-2,6-二甲基-6-O-β-D-吡喃鸡纳糖基-2,7-辛二烯酸基]-金合欢酸-28-O-α-L-呋喃阿拉伯糖基(1→4)[β-D-吡喃葡萄糖基(1→3)]-α-L-吡喃鼠李糖基(1→2)-β-D-吡喃葡萄糖苷,金合欢酸3-O-β-D-吡喃葡萄糖基(1→3)-β-D-吡喃夫糖基(1→6)[β-D-吡喃木糖基(1→2)]-β-D-吡喃葡萄糖苷;2个已知化合物结构分别是:金和欢酸内酯3-O-β-D-吡喃木糖基(1→2)-β-D-吡喃夫糖基(1→6)-β-D-2-去氧-2-乙酰氨基吡喃葡萄糖苷,金和欢酸内酯3-O-β-D-吡喃木糖基(1→2)-α-L-吡喃阿拉伯糖基(1→6)-β-D-2-去氧-2-乙酰氨基吡喃葡萄糖苷。

According to the study result of species selection,12 species of Eucaly-ptus and Acacia were introduced in 1993 in Yuanmou of Yunnan Province Through observing and analysing for more than 2 years and comparing the adaptability and rapidly-growing ability with Leucaena lecocephala introduced successfully before the authors found that Eucalyptus camaldulensis,A auriculiformis ,A caciamangium were the optimal afforestation species in dry-hot river valley of Yuamou This had certain significance to guide...
根据树种选择研究结果,1993年在云南元谋引种桉属和金合欢属树种12个,经两年多的初步观测分析,并与原引种成功的新银合欢比较适应性和速生性,认为赤桉、大叶相思、马占相思可作为元谋干热河谷造林的最优树种,逐步扩大栽培试验,对当地植被恢复适生树种的使用具有一定指导意义。

Leucaena:银合欢属
例如新银合欢属(Leucaena)与牧豆属(Prosopis)的杂种在南非某些局部地区为入侵树种. 南非曾对入侵树种对自然生境的影响进行过量化分析,发现入侵树种会导致局部生物多样性大量减少,并妨碍集水区内的自然径流,进而影响干旱地区水源供应.
