氢化松香主要化学组成的研究

STUDY ON MAIN CHEMICAL CONSTITUENTS OF HYDROGENATED ROSIN

利用改进的DEAE Sephadex离子交换色谱从自制氢化松香中分离出主要化学组成———酸性部分 ,然后采用DB 5毛细管柱对其进行GC MS DS分析。共鉴定出 6种二氢枞酸型树脂酸 ,4种二氢海松酸 /异海松酸型树脂酸 ,2种四氢枞酸型树脂酸。其主要成分为 13 二氢枞酸、8 二氢枞酸、8α ,13β 四氢枞酸 ,13β 7 二氢枞酸及 8(14)

The acid fraction, which is the main part of the hydrogenated rosin prepared by authors, was separated from neutrals by modified DEAE Sephadex ion exchange chromatography and analyzed by GC MS DS technique using DB 5 capillary column. Six dihydroabietic type resin acids, four dihydropimaric/isopimaric type resin acids and two tetrahydroabietic type resin acids were identified. The hydrogenated rosin is composed mainly of 13 abietenoic acid, 8 abiete noic acid, 8 α,13 β abietenoic acid, 13β 7abietenoic acid and 8(14) pimarenoic acid, ect.
