[Objectives] To study the material foundation of liposoluble constituents from buds,flowers and fruits of Millettia speciosa Champ.and provide a reference for the development of flowers and fruits of Millettia speciosa Champ.[Methods]The liposoluble constituents were extracted from buds,flowers and fruits of Millettia speciosa by Soxhlet extraction and solvent extraction method,and analyzed by GC-MS.[Results]24 compounds were identified from the liposoluble constituents of buds,accounting for 88. 31 % of the total liposoluble constituents,mainly comprising alkanes and olefins compounds( 52. 00%) and alcohols compounds( 17. 46%); 29 compounds were identified from the liposoluble constituents of flowers,accounting for 91. 38 % of the total liposoluble constituents,mainly comprising alkanes and olefins compounds( 60. 64%) and alcohols compounds( 17. 17%); 32 compounds were identified from the liposoluble constituents of fruits,accounting for 80. 01 % of the total liposoluble constituents,mainly comprising alkanes and olefins compounds( 32. 56%),phenyl and its derivatives compounds( 22. 46%) and fatty acids compounds( 12. 54%). 6 compounds were common in buds,flowers and fruits. [Conclusions] Although there were some differences in liposoluble constituents from flowers,fruits,leaves and roots of Millettia speciosa Champ.,the different parts of Millettia speciosa Champ. had development value.
