| 1 | Two Novel Sub-skeleton Types of ent-Kauranoids from Isodon gesneroides显示文摘Two novel ent-kauranoids with new sub-skeleton types, gesneroidins G and H were isolated as white powder from the ether extract of the leaves of Isodon gesneroides through normal phase column chromatography. Their structures were elucidated as 3b,6a,7b-triacetoxyl-15-hydroxyl-14-oxo-ent-15,16-seco-kaur-11,17-olide and 1a-hydroxyl-3b,6a,7b,11b-tetraacetoxyl-ent-nor-15,17-kaur-8,16-olide on the basis of the spectral evidences including 1D and 2D NMR spectra. | ShaoNongCHEN ShaoYuanCHEN HanDongSUN WenZhongLIN YaoZuCHEN | 2004 | Chinese Chemical Letters2004，15，5： | 0 |
| 2 | A New Taxoid from Leaves and Branches of Taxus chinensis显示文摘A new taxoid, 2-deacetyl-2a, 14b-dihydroxybaccatin IV (1), was isolated from the leaves and branches of Taxus chinensis together with the known compound baccatin IV (2). The structure of the new compound was elucidated by spectroscopic techniques. The detailed 13C NMR assignments of baccatin IV are reported for the first time. | FuShengWANG LiYanPENG YuZHAO QinShiZHAO KunGU HanDongSUN | 2004 | Chinese Chemical Letters2004，15，3： | 0 |
| 3 | A Styrylpyrone Dimer from the Bark of Goniothalamus leiocarpus显示文摘A dimer of styrylpyrone derivative, leiocarpin E (1), was isolated from the bark of Goniothalamus leiocarpus. Its structures was elucidated by means of spectral and chemical methods. The cytotoxicity of leiocarpin E against HL-60 cells was tested. | QingMU YiNengHE WeiDongTANG ChaoMingLI LiGuangLOU HanDongSUN BinXU GuoXunYANG ChangQiHU | 2004 | Chinese Chemical Letters2004，15，2： | 0 |
