constituents of the sap of the Burmeselactree, Melanorrhoea usitate have been identified. The sap consists of homologues of thitsiol ( ca 20 %), laccol ( ca 10 %), urushiol (4 %), 3-substituted catechols with 12-phenyldodecyl ( ca 30 %), or 10-phenyldecyl groups ( ca 8 %), 4-substituted catechols ( ca 3 %), and 5-substituted resorcinols ( ca 1 %), with the same substituents. 3-Substituted phenols with characteristic
摘要 缅甸紫胶树 Melanorrhoea usitate 的 28 种成分已被鉴定。树液由噻硫醇 (ca 20 %)、laccol (ca 10 %)、漆酚 (4 %)、具有 12-苯基十二烷基的 3-取代邻苯二酚 (ca 30 %) 或 10-苯基癸基 (ca 8 %) 的同系物组成、4-取代的儿茶酚 (ca 3%) 和 5-取代的间苯二酚 (ca 1%),具有相同的取代基。含有特征侧链基团的 3-取代酚也较少。讨论了这些次生植物代谢物的生物合成途径,尤其是具有 (ω-苯基烷基侧链) 的新型酚类脂质。
