摘　　要：降香提取物作为一种中药复方组分,可以用来治疗心血管疾病。一般采用水蒸气蒸馏法,从降香植物的根或茎中提取,本研究采用超临界CO2流体萃取技术从降香叶中提取其药用有效成分,通过正交实验,得到最佳工艺工条件是:萃取压力30MPa,萃取温度40℃,夹带剂量400mL,原料粒度0.8mm,而采用水蒸气蒸馏法产物收率极低。表明超临界CO2萃取法优于水蒸气蒸馏法。Dalbergia Wood Extract is a component of Chinese medicine complex prescription. It can treat cardiovascular disease. It obtains from root or stem of Dalbergia Wood by the method of Water Vapour Distillation. The paper researches on supereritical CO2 extraction of available medical composition from dalbergia wood leaf. Its optimum technical conditions from the design of orthogonal experiments are： extracting pressure at 30 MPa, temperature 40℃, entrainer volume 400ml, particle size of raw material 0.8mm. The yield of Water Vapour Distillation from Dalbergia Wood is very low. It shows that Supercritical CO2 Extraction is prior to water vapor distillation.
