Especially after primary distillation, the high volatile components of 1-decanol and α-terpineol, which were of the highest relative conten t, were remarkably declined, even could not be found. The volatile constituents were also lost after rectification. Some constituents with weak volatility were lost because of the excipient, cosolvent and filtration.
特别是经初馏后，原药材中两种相对含量最高的强挥发性成分1-癸醇和α-萜品醇在初馏液中含量明显下降，甚至检测不到；重蒸馏过程也使挥发性成分受到破坏；辅料、助溶剂等的加入和滤过环节使挥发性较弱的成分也在一定程度上受到损失。
