| 摘 要： | 水杉脂为无色或乳白色透明状非晶体，具芳香味，溶于乙醇、乙醚等有机溶剂，微溶于苯、石油醚等，微热易溶于甲醇。在自然存放过程中，水杉脂的颜色逐渐加深呈淡黄色或黄色。研究结果显示，水杉脂的软化点、中性物质含量较高，酸值较低，树脂酸的种类与脂松香一致，但含量存在一定差异。

| Abstract: | Chemical composition and physical chemical properties of Metasequia glyptostroboides gum were studied in this paper. M.glyptostroboides gum were cream colored,transparent and amorphous.Its softening point and unsaponifiable content were higher and saponification number were lower than those of Pinus massoniana rosin.The two samples contain similar kinds of rosin acids with certain difference in their contents. |
