裸花紫珠叶中二萜类成分及其抗炎活性研究
Diterpenoids from leaves of Callicarpa nudiflora and their anti-inflammatory activities
摘要
Abstract
The chemical constituents and anti-inflammatory activities of the leaves of Callicarpa nudiflora were investigated using various chromatographic separation methods.Eight diterpenoids were isolated from the ethyl acetate extract and identified by MS and NMR data analysis as calnudiflopene A(1),(5S,9S,10S,12S,13R)-3,4-seco-12,13-dihydroxy-4(18),8(17),14(15)-labdatrien-3-oic acid(2),3,4-seco-12R,13S-dihydroxy-4(18),8(17),14(15)-labdatrien-3-oic acid(3),nudiflopene B1(4),nudifloid F(5),(5S,9S,10S)-3,4-seco-16-carbonyl-15,16-epoxy-4(18),8(17),11(E),13(14)-labdatetraen-3-oic acid(nudiflopene G1)(6),callicarpaolide(7),and 7α-hydroxysandaracopimaric acid(8).Among them,compound 1 is a new 3,4-seco-labdane diterpenoid,in which a linear monoterpenoid is ester-linked to compound 2.Compound 2 was obtained by alkaline hydrolysis of compound 1,and its absolute configuration was determined by single-crystal X-ray diffraction,thereby establishing the absolute configuration of compound 1.The anti-inflammatory activities of all compounds were evaluated in RAW264.7 cells induced by lipopolysaccharide(LPS).Compounds 1 and 5 exhibited certain activity,with IC50 values of(22.8±0.52)and(31.2±0.85)μmol·L-1,respectively.关键词
