Abstract

Three new unsaturated fatty acids, (Z)-9,10,11-trihydroxy-12-octadecenoic acid (1), (Z)-7,8,9-trihydroxy-10-hexadecenoic acid (2) and (Z)-12-keto-7,8,9-trihydroxy-10-hexadecenoic acid (3) were isolated from the roots of Boehmeria nivea (L.) Gaudich, along with a known unsaturated fatty acid, (E)-8,11,12-trihydroxy-9-octadecenoic acid (4). The structures of the new compounds were established by HR ESI-MS, 1H, 13C, 2D (1H-1H COSY, HSQC, HMBC) NMR experiments. The known compound was identified by a comparison of its spectral data with published references. The three new compounds showed some antifungal activities by agar assay.
