| 摘要: |
| 对广西高峰林场引种的8年生马占相思(Acacica mangium)树皮进行定性和定量分析,模拟栲胶生产小试。结果表明:该树皮所含单宁属缩合类单宁,绝干树皮含单宁高达36.75%,单宁/非单宁为6.10,约2.34 t气干树皮可生产1t栲胶。制得的栲胶不仅单宁含量高,颜色浅,而且鞣革渗透速度快,富有弹性,皮质好,说明马占相思树皮是一种优良的栲胶原料。 |

| Abstract: |
| The qualitative and quantitative analyses were conducted on the bark of the eight-year old individuals of Acacica mangium growing at Guangxi Gaofeng Forest Farm. The experimental production of vegetable tannin was extracted in small scale. The tannin in the bark is a kind of the condensed tannins. The absolutely dried bark contains up to 36.75% of tannin, with 6.10 of ratio of tannin to non-tannin. About 2.34 tons of the air dried bark could produce one ton vegetable tannin.The production has a high tannin content with a quality of light color, quick permeation, tan leather and springy. It is revealed that the bark of Acacica mangium is an excellent raw material of vegetable tannin extraction. |
