Two new xanthones, 7-hydroxydesoxymorellin (1) and isocaledonixanthone D (2), and four known ones, gaudichaudione H, 1,7-dihydroxy-3-methoxy-2-(3-methyl-2-butenyl)xanthone, 1,5-dihydroxy-3-methoxy-2-(3-methyl-2-butenyl)xanthone, and 1,3,7-trihydroxy-2-(3-methyl-2-butenyl)xanthone, as well as lupeol were isolated from the leaves of Garcinia urophylla (Guttiferae). Their structures were determined using a combination of 1D (1 H NMR, 13 C NMR, DEPT) and 2D (COSY, gHSQC, gHMBC) NMR spectroscopic techniques. Among the isolates, 7-hydroxydesoxymorellin (1), gaudichaudione H, 1,5-dihydroxy-3-methoxy-2-(3-methyl-2-butenyl)xanthone, and 1,3,7-trihydroxy-2-(3-methyl-2-butenyl)xanthone demonstrated cytotoxic activities against breast (MCF-7), prostate (DU-145), and lung (NCI-H460) human cancer cell lines.

The study was aimed to evaluate the anticancer activity of the Soft Halicona species on the HeLa cell line. The Soft Halicona species methanol and Dichloromethane extracts were tested for its inhibitory effect on HeLa cell line. The percentage viability of the cell line was carried out by using colorimetric method. The cytotoxicity of Soft Halicona specieson HeLa cell was evaluated by MTT assay. Both the methanol and Dichloromethane extract has significant cytotoxic effect on HeLa cell line in concentration range between 0.1µg/ml to 100µg/ml by using MTT assay. R2 value of Soft Halicona species on HeLa cell of methanol extract was 0.8316 and for dichloromethane extract was 0.6699 and percentage cell inhibition for methanol extract 61.40% and Dichloromethane extract was 46.98%.
