摘要:

Two compounds with different bioactivitieswere isolated from the leaves of the Lantana camara Linn plant. Compound 1wastriterpenoid (Lantadene B)(22β-dimethylacroyloxy-3-oxoolean-12-en-28-oic-acid, C35H52O5), which was isolatedfrom n-hexane fraction and obtained as white solid (amorphous). Compound 2was glycosideflavonoid (5-hydroxy-6,4′-dimethoxyflavon-7-O-glucopyranose, C23H24O11), which was isolated from ethyl acetate and obtained as pale yellow solid (amorphous). Extraction was performed withmaceration method using methanol solvent. Subsequently, fractionation was carried out using n-hexane and ethyl acetate solvents. Isolation and purification of both fractions were conductedusing chromatography method. The structure of the isolated compounds was determined throughspectralanalyses of ultraviolet (UV), infrared (IR), and nuclear magnetic resonance (1H NMR and 13C NMR), distortionless enhancement by polarization transfer (DEPT), heteronuclear multiple bond connectivity (HMBC), heteronuclear single quantum correlation (HSQC), and H-H COSY (1H-1H homonuclear correlatedspectroscopy). The cytotoxic activity of compound 1 was tested against MCF-7 breast cancer cellsin vitro using MTT assay (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), showing very strong cytotoxic activity in inhibiting the growth of MCF-7 breast cancer cells, and the IC50 value was 1.1336 µM. The antioxidant activity of compound 2 was tested using DPPH assay (1,1-diphenyl-2-picrylhydrazyl), showing strong activity in inhibiting free radicals, and its IC50 value was 71.03 mg/L.
