The Summary Of The Chemical Constituents And The Pharmacology Of Glochidion And Study On The Chemical Constituents From Glochidion Lanceolarium

This thesis is composed of three chapters.Chapter1: Summary of the chemical constituents and the pharmacology of GlochidionThis chapter is a summary of the chemical constituents and the pharmacology ofGlochidion.64new compounds were isolated from Glochidion since1965.Chapter2: Isolation of chemical composition from the aerial parts of GlochidionlanceolariumThe chemical composition of Glochidion lanceolarium were isolated by a few of means.The total flow chart was drawed which is used for describing methods for extracting the plant.Chapter3: Identification of chemical constituents from the aerial parts of GlochidionlanceolariumFrom the95%EtOH extract of the aerial parts of Glochidion lanceolarium,15compounds were isolated. The structures of ten of them were identified on the basis ofphysical and chemical properties and spectroscopic methods including IR, EI-MS,1H-NMR,13C-NMR, DEPT,1H-1HCOSY, HMQC and HMBC, they are: glochidone(1), lupeol(2),3-epi-lupeol(3), β-sitosterol(6), glochidonol(7),1up-20(29)-en-1β,3β-diol(8), glochidiol(9),lup-20(29)-an-3α,23-diol(10), Lup-20(29)-ene-lβ,3α,23-triol(12) and oleanolin acid(15).Among them compounde12is a new compound.
