Abstract

The invention belongs to the field of pharmaceutical production, and in particular relates to an extraction method of dalbergia odorifera volatile oil. Aiming at the problems that the extraction method of the volatile oil in the prior art is high in energy consumption, long in time consumption, low in efficiency and oil yield, less in charging amount, not enough in purity after purification, and the like, the invention provides a new extraction method of the dalbergia odorifera volatile oil. The method comprises the three steps of medicine pretreatment, distilling extraction and oil-water separation. Furthermore, the method adopts the operation such as filling pure steam at uniform velocity for distilling and condensing by using a two-stage condenser pipe, thus improving the extraction efficiency; the extraction method is free from environmental pollution, safe and reliable, low in energy consumption, high in oil yield, simple in operation and low in cost, thus very easily realizing industrial production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical production, and in particular relates to a method for extracting balsamic volatile oil. Background technique [0002] Dalbergia is the dry heartwood of the trunk and root of Dalbergia odorifera T.Chen, a leguminous plant. It is mainly produced in Hainan, Guangdong, Guangxi, Yunnan and other places. It has the effects of removing blood stasis, stopping bleeding, regulating qi and relieving pain. Liver depression and hypochondriac pain, chest pain tingling, etc., its main active ingredients are volatile oil and flavonoids, and the main ingredient of balm oil is trans-nerolidol. Dalbergia oil is often used as a raw material to prepare "Guanxin Danshen Dropping Pills", "Guanxin Danshen Tablets" and "Shuangxiangyou Soft Capsules", and is widely used in the treatment of coronary heart disease clinically. [0003] Commonly used methods for extracting balsamic volatile oil include steam distillation and sup...
