Abstract Methanolic extract of Miliusa balansae Finet et Gagnep exerts an anti-inflammatory effect via inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated murine RAW 264.7 macrophage cells. Three new megastigmane glycosides, milbasides A-C (1-3), together with fifteen known compounds (4-18), were isolated from the active fraction. Their chemical structures were elucidated using extensive spectroscopic analyses, including 1D and 2D NMR, HR ESI MS, and CD analysis, as well as comparison with previously reported data. Compounds 1-3, 11 and 14 (20.0 μM) showed potent inhibitory activities with inhibition values of 98.5 ± 1.6%, 90.9 ± 7.8%, 84.8 ± 3.5%, 91.5 ± 8.7%, and 91.8 ± 2.7%, respectively. Our results suggest that megastigmane glycosides from M. balansae leaves may be used to treat inflammatory diseases.

From the 1-BuOH-soluble fraction of a methanol (MeOH) extract of the leaves of Croton cascarilloides, crotofolanes: crotocascarins I-K, nor-crotofolane: crotocascarin γ, isocrotofolane glucoside and phenolic glycoside were isolated by a combination of various separation techniques. Their structures were elucidated mainly from the NMR spectroscopic evidence. The structure of crotocascarin K was first elucidated by spectroscopic analysis and then was confirmed by X-ray crystallographic analysis. Its absolute structure was finally determined by the modified Mosher's method. Isocrotofolane glucoside was found to possess a new skeleton, however, its absolute structure remains to be determined.

The saponin composition of leaves and roots from Medicago marina L., sea medic, was investigated by a combination of chromatographic, spectroscopic and spectrometric (GC, LC, ESI-MS/MS, NMR) methods. Several compounds were detected and quantified by HPLC using the external standard method. Saponins from this plant species consist of a mixture of high molecular weight bidesmosidic derivatives of medicagenic and zanhic acid, containing up to six sugars in the molecules. Six of the detected saponins were previously isolated and reported as constituents of other Medicago spp.; one saponin was previously described in other plant species; four saponins are undescribed compounds in Medicago and never reported before in other plant species. These are: 3-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranosylzanhic acid 28-O-β-D-xylopyranosyl-(1 → 4)-[β-D-apiofuranosyl-(1 → 3)]-α-L-rhamnopyranosyl-(1 → 2)-α-L-arabinopyranosyl ester; 3-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranosylzanhic acid 28-O-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-α-L-arabinopyranosyl ester; 3-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranosylmedicagenic acid 28-O-β-D-xylopyranosyl-(1 → 4)-[α-L-arabinopyranosyl-(1 → 3)]-α-L-rhamnopyranosyl-(1 → 2)-α-L-arabinopyranosyl ester and 3-O-β-D-glucopyranosylmedicagenic acid 28-O-β-D-xylopyranosyl-(1 → 4)-[α-L-arabinopyranosyl-(1 → 3)]-α-L-rhamnopyranosyl-(1 → 2)-α-L-arabinopyranosyl ester. The specific saponins synthesized by M. marina may have a role in its tolerance to environment, representing a reservoir of osmolytic sugars.
