The dried rhizomes of Curculigo orchioides G. yielded two phenolic glycosides, curculigoside (1), orcinol-β-D-glucoside (4), and two cycloartane saponins, curculigosaponin G (2), curculigosaponin I (3). The structures were determined using spectroscopic methods. Among these isolates, compound 1 exhibited potent inhibitory activity against matrix metalloproteinase-1 in cultured human skin fibroblasts. In addition, it increased the level of Bcl-2 protein expression and decreased the level of Bax protein expression. Compound 4 was isolated from this plant for the first time.
