Vasorelaxing activity of two coumarins from Murraya paniculata leaves.
In the search for novel chemical scaffolds leading to potential antihypertensive agents, the methanol extract of Murraya paniculata leaves was assessed for its effects on isolated rat aorta rings. The vasorelaxing effect of the chloroform fraction of the methanol plant extract was the most potent for its vasorelaxing activity on rat aorta rings contracted by 60 mM K(+) (K60). Two coumarins were...
متن کاملPreparative isolation and purification of coumarins from Peucedanum praeruptorum Dunn by high-speed counter-current chromatography.
A preparative high-speed counter-current chromatography (HSCCC) method for isolation and purification of coumarins from Peucedanum praeruptorum Dunn (Baihuaqianhu in Chinese) was successfully established by using light petroleum-ethyl acetate-methanol-water as the two-phase solvent system in gradient elution mode. The upper phase of light petroleum-ethyl acetate-methanol-water (5:5:5:5, v/v) wa...
متن کاملNew monoterpenoid coumarins from Clausena anisum-olens.
Two new monoterpenoid coumarins: anisucumarin A (1) and B (2), a pair of epimers, were isolated from Clausena anisum-olens. Their structures were established based on extensive spectroscopic analyses.
متن کاملBioactive Compounds from the Stems of Clausena lansium.
In view of the significant neuroprotective effect of Clausena lansium, we continued to separate the n-butanol and the water extracts from the stems of C. lansium in order to find the leading compounds with significant activity. Two new phenolic glycosides, Clausenolside A-B (1-2), one new pair of phenolic enantiomers (3a, 3b), and two new monoterpenoids, clausenapene A-B (4-5), together with tw...
متن کاملCytotoxic constituents from the stems of Clausena lansium (Lour.) Skeels.
Six compounds were isolated from the stems of Clausena lansium (Lour.) Skeels by repeated sillica gel column chromatography. Their chemical structures were elucidated on the basic of physicochemical and spectroscopic data. Among them, 8-geranyloxypsolaren (3) and 2-methoxy-1-(3-methyl-buten-1-yl)-9H-carbazole-3-carbaldehyde (6) were isolated for the first time from this plant. These compounds w...
