Zhong Yao Cai. 2015 Mar;38(3):514-7. | Chemical Constituents of Euphorbia lunulata.[Pubmed: 26495651] | To investigate the chemical constituents in the ethanol extract from the whole plant of Euphorbia lunulata. METHODS AND RESULTS: The whole plant of Euphorbia lunulata was extracted by 95% ethanol, then partitioned by system solvents with different polarity. The ethyl acetate and n-butyl alcohol extracts were separated on silica gel, Sephadex LH-20,and MCI columns. The isolated compounds were determined by detailed analysis of their spectral data. Twelve compounds were isolated and identified from the ethyl acetate and n-butyl alcohol extracts of Euphorbia lunulata and the structures were identified as 7β-methoxy-stigmast-5-ene-3β-ol (1), 7β-methoxy-stigmast-5-ene-3β,22β-diol(2), asperglaucide(3), Moscatin (4), p-hydroxybenzoic acid (5),3-methoxy-4-hydroxy benzoic acid(6), erigeside C(7),5,7,4'-trihydroxy flavanone(8), kaempferol(9), quercetin(10), corosolic acid(11) and acacetin (12). CONCLUSIONS: All compounds except for 9 and 10 are reported from this plant for the first time. |
