Abstract: Seven compounds were isolated from the roots of Premna microphylla. By combination of chemical methods and spectral analyses, structures of the compounds were identified asβ-sitosterol (1), palmitic acid (2), trans-p-methoxycinnamic acid (3), eugenin (4), luteolin (5), luteolin-7-O-β-D-glucopyranoside (6) and pedalitin (7). All of these compounds were obtained from this plant for the first time.
