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.

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。
