Studies On The Chemical Constituents Of Lysimachia Paridiformis Franch. And Ecdysanthera Rosea Hook.et Arn.

This dissertation is composed of three chapters. In the first chapter, the chemical constituents from plant of Lysimachia were reviewed. In chapter 2, a chemical research of Lysimachia paridiformis Franch. .were carried out, 16 compounds were isolated by various chromatographies over silica gel column, reverse phase column (RP-18,RP-2), Sephadex LH-20, MPLC, semi-pre HPLC and identified by 1D, 2D NMR, MS (FAB, EI, ESI, HR), IR, UV. They are (25R)-3-O-[β-D-glucopyranosyl-(1→2)-β-D -glucopyranosyl-(1→4)-β-D-galactopyranosyl]-5 α-spirost-9(11)-en -12-one (1), gentrogenin-3- O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside(2), (25R)-3-O- [β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl -(1→4)-β-D-galactopyranosyl]-5α-spirost-12-one(3), (25R)-3,6-di-O-(β-D-gluco pyranosyl)-5α-spirost-3β,6α,23 α-triol(4),(25R)-6-O-(β-D-glucopyranosyl)-5α-spirost-3β, 6α-diol(5), (25R)-3,6-di-O-(β-D- glucopyranosyl)-5α-spirost-3β,6a-diol(6), (25R)-5α-spirost-3β, 6α, 23α-triol(7), β-sitosterol(8), daucosterol(9), 3β-O-[β-D-xylopyranosyl- (1→2) -O-β-D-glucopyranosyl- (1 →4) ] - [0-β-D-gluco pyranosyl- (1→2)] -O-α-L-arabinopyranosyl 16α-hydroxy-13β-28-epoxy-oleanan (10), Cyclamiretin A-3-O- {β-D-xylopyranosyl-(l → 2)-β-D-glucopyranosyl - (1→2)-[β-D-glucopyranosyl- (1 → 4)]} - α-L-arabinopyranoside (11), isorhamnetin 3-0-rutinoside (12), quercetin 3-0-rutinoside (13), β-amyrin(14), β-amyrin acetate (15), dotriacontanol (16). Among them, compound 1 was a new compound. Finally a study on the chemical constituents of Ecdysanthera rosea Heok...
