[Abstract]
Objective To study the chemical constituents from the roots of Campanumoea javanica and their antiangiogenesis activities. Methods The compounds were isolated and purified by various chromatographic techniques and their structures were elucidated by spectral analysis, the antiangiogenic activities of the isolated compounds were evaluated using a zebrafish model. Results Fourteen compounds were isolated and identified from 90% ethanol extract in ethyl acetate fraction in the roots of C. javanica, including campanumoside (1), lobetyol (2), tetradeca-4E,8E,12E-triene-10-yne-1,6,7-triol (3), 9-(tetrahydropyran-2-yl)-non-trans-8-ene-4,6-diyn-3-ol (4), 9-(tetrahydropyran-2-yl)-nona-trans,trans-2,8-diene-4,6-diyn-1-ol (5), lobetyolinin (6), (Z)-3-hexenyl-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (7), 3,4-dihydroxybenzoic acid (8), tangshenoside II (9), zanthocapensol (10), ampelopsin (11), agathisflavone (12), β-ecdysterone (13), and α-tocopherolquinone (14). Conclusion Compound 1 is a new polyacetylene glucoside named campanumoside. Compounds 2-14 are isolated from the plants of Campanumoea Bl. for the first time. Compounds 3 and 4 exhibit the certain antiangiogenic activity in the pharmacological evaluation with a zebrafish model.
