Research Update

Iridoid glucosides from Wendlandia ligustroides (Boiss. &Hohen.) Blakelock

Eight iridoid glucosides were reported from the aerial parts of Wendlandia ligustroides. 10-deoxygeniposidic acid (1), 7-deoxygardoside (2), geniposidic acid (3), 7-deoxy-8-epi-loganic acid (4), deacetyl-daphylloside (5), scandoside methyl ester (6), 6-O-methyl-deacetyl-daphylloside (7), 6-O-methyl-scandoside methyl ester (8). Compounds 3 - 8 were isolated as a pure form while 1 and 2 as a mixture. The structures of the compounds 1 - 8 were established by spectroscopic methods including 1D-NMR (1H NMR, 13C NMR, DEPT-135), 2D-NMR (COSY, NOESY, HSQC, HMBC) and HRMS.

[Iridoids of Borreria verticillata]

Seven iridoids are isolated from Borreria verticillata root barks: daphylloside 1, asperuloside 2, feretoside 3, methyl desacetylasperulosidate 4, desacetylasperuloside 5, asperulosidic acid 6 and desacetylasperulosidic acid 7. Their structures result from spectroscopic analysis and are proved by chemical correlation.

Antioxidant iridoid glucosides from Wendlandia formosana

Two new iridoid glucosides of 10-O-caffeoyl scandoside methyl ester (3), and 6-methoxy scandoside methyl ester (4) besides the known compounds of scandoside methyl ester (1), methyl deacetyl asperulosidate (2), 10-O-caffeoyl daphylloside (5), phytol (6), and ursolic acid (7) were isolated from the leaves of Wendlandia formosana. Structure elucidation of the new iridoid glucosides was based on interpretation of high-resolution 1D and 2D NMR spectral data and chemical conversions. Antioxidant activity of Compounds (1-5) against diphenylpicrylhydrazyl (DPPH) and hydroxyl radical, and peroxynitrite was reported.

[Chemical Constituents from Oldenlandia diffusa]

Objective: To study the chemical constituents of water extracted fraction from Oldenlandia diffusa.
Methods: The compounds were isolated and purified by column chromatography on macroporous resin,silica gel,MCI gel,Sephadex LH-20,ODS medium pressure liquid chromatography and RP-semi-preparative HPLC. The structures of compounds were elucidated on the basis of physicochemical and spectral analysis.
Results: 16 compounds were isolated from the water extract of Oldenlandia diffusa,and their structures were identified as asperuloside( 1),deacetyl asperuloside( 2),geniposide( 3),10-dehydrogeniposide( 4),daphylloside( 5),diffusoside A( 6),diffusoside B( 7),coniferin( 8),scandoside methyl ester( 9),acetyl scandoside methyl ester( 10),deacetylasperulosidic acid methyl ester( 11),gardenoside( 12),galioside( 13),galioside 10-acetate( 14),loliolide( 15) and( +)-neo-olivil( 16),respectively.
Conclusion: Compounds 3,8 and 14 ~ 16 are obtained from Oldenlandia diffusa for the first time.

[Study on chemical constituents of iridoids from eucommiae folium]

Objective: To investigate the chemical constituents of iridoids from Eucommiae Folium.
Methods: The compounds were isolated and purified by various column chromatography, the structures were identified on the basis of physiochemical properties and spectral analysis.
Results: Nine iridoids were isolated and identified as asperuloside (1), daphylloside (2), scandoside methyl ester (3), loganin (4), 8-epi-loganin (5), 7-epi-loganin (6), deacetyl asperulosidic acid methyl ester (7), geniposide (8) and geniposidic acid (9).
Conclusion: Compounds 2 - 7 are isolated from this plant for the first time, compounds 4 - 6 are isolated from this genus for the first time.
