Heptaellipside A, a rare new 2,28-bidesmosidic lupane-type saponin from the leaves of .

For the first time, phytochemical constituents of the leaves of were investigated. One rare new 2,28-bidesmosidic lupane-type saponin, named heptaellipside A (), along with four other lupane-type analogs () were purified by combining differently chromatographic methods. All of the separated compounds () were communicated for the first time from .

Cycloartane-type triterpenoids from the whole plants of .

One new cycloartane-type triterpenoid, named macrobidoupoic acid A (as an C-24 epimeric mixture, , ), together with three known ones (-), were clarified by different chromatography from the whole plants. Triterpenoids ( & ) were detected for the first time from the genus. Chemical structures of them were illuminated using HR-ESI-MS, and NMR (1 D & 2 D) assessments.

Macrotricolorin A, a new diarylpropanoid from the Vietnamese plant (Lecomte) Danser.

From the Vietnamese plant (Lecomte) Danser, one new diarylpropanoid, named macrotricolorin A () together with three diarylheptanoids including bisdemethoxycurcumin (), demethoxycurcumin () and curcumin (), were isolated. Their structures were elucidated by intensive analyses of their IR, UV, HR-ESI-MS and NMR (1 D & 2 D) spectra. It is the first time that diarylalkanoids have been reported from the genus Compound exhibited anti-inflammatory activity against the nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW264.

Markhacanasin C, cycloartane triterpenoid from the leaves of Markhamia stipulata var. canaense V.S. Dang.

One new cycloartane triterpenoid, named markhacanasin C (1), together with three known triterpenoids, oleanolic acid (2), ursolic acid (3) and 6β,19α-dihydroxyursolic acid (4) were isolated by various chromatographic methods from the most cytotoxic fraction of the ethyl acetate extract of Markhamia stipulata var. canaense V.S.

Two new flavonol glycosides from the leaves of Cleome chelidonii L.f.

From the leaves of Cleome chelidonii L.f., two new flavonol glycosides, named cleomesides A (1) and B (2), and four known compounds, quercetin 3-O-β-glucopyranosyl(1 → 2)-α-rhamnoside-7-O-α-rhamnoside (3), ethyl α-galactopyranoside (4), adenine (5) and glycerol monostearate (6), were isolated.
