OBJECTIVE: To study the chemical constituents of the Chinese liverwort Trocholejeunea sandvicensis (Gott.) Mizut. METHODS: After extraction with ethanol, the obtained extract was separated and analyzed over silica gel and Sephadex LH - 20. Their structures were identified by the spectral data of IR, MS and NMR. RESULTS: The structures of six compounds were identified as: stigmosterol arachidate (I), β-sitosterol (II), 7,4′-dimethoxy-5-hydroxyflavoniod(III) glycerin monopalmitate (IV), dausosterol (V) and sucose (VI). CONCLUSION: These compounds were obtained from this plant for the first time.
