  • Two triterpenoids, 24-methylene-3,4-seco-cycloart-4(28)-en-3-oic acid (1) and 3-oxo-$9{\beta}$-lanosta-7,22Z,24-trien-26,23-olive (6) were isolated from Abies koreana, together with $\beta$-sitosterol (2), maltol (3), ${\beta}-sitosterol-O-{$\beta}-D-glucoside$ (4), and hexacosylferulate (5). The structures of the compounds were established based on the spectroscopic data. The cytotoxic activities of triterpenoids have been evaluated using the sulforhodamine B (SRB) method. Compound 1 showed moderate cytotoxicities against human lung carcinoma (A549), ovarian carcinoma (SK-OV-3), malignant melanoma (SK-MEL-2), and colon carcinoma (HCT-15) cell lines.

  • Eleven compounds, lupenone (1), lupeol (2), stigmasterol (3), β-sitosterol (4), 24-methylene-3,4-seco-cycloart-4(28)-en-3-oic acid (5), 24-methylene-3,4-seco-cycloart-4(28)-en-3-methyl ester (6), (+)-(1S,4R)-7-hydroxycalamenene (7), hibicuslide C (8), isopropyl-${\beta}$-D-glucopyranoside (9), syringaresinol-4'-O-${\beta}$-D-glucoside (10), and rutin (11) were isolated from the aerial parts of Abutilon theophrasti. The chemical structures of compounds 1-11 were determined by the basis of physicochemical properties and spectroscopic methods such as 1D and 2D NMR. These compounds were isolated from this plant for the first time. In addition, compounds 6 and 9 were obtained for the first time as natural products not as synthetics.
