Abstract

The invention relates to a preparation method of nutmeg oil without safrole. The method comprises the following steps: carrying out multistage reduced pressure rectification on nutmeg oil to obtain safrole-free nutmeg oil rectification liquid 1#, safrole-rich nutmeg oil rectification liquid 2# and safrole-free nutmeg oil kettle bottom liquid, and mixing the nutmeg oil rectification liquid 1# withthe nutmeg oil kettle bottom liquid to obtain the nutmeg oil (safrole removed). The content of safrole in the nutmeg oil (safrole removed) is less than 1 [mu]g / g, so that the safety of the product isgreatly improved, and the application range of the product is widened. The method meets the requirements of simplicity and convenience in operation, low cost and energy conservation, the materials areprevented from being oxidized and decomposed through reduced-pressure rectification operation, and the obtained nutmeg oil (safrole removed) is pure in fragrance.

Description

technical field [0001] The invention relates to a process for removing safrole from nutmeg oil. [0002] technical background [0003] Nutmeg (Myristica fragrans Houtt.) belongs to the dry mature seed kernel of Myristicaceae Myristicaceae, also known as Kakul, cardamom, fruit, head meat, etc., distributed in Malaysia, Indonesia, West Indies, etc., in Taiwan, my country , Guangdong, Yunnan and other places have introduced and cultivated. Nutmeg is warm in nature, strong in aroma, pungent in taste, and returns to the spleen, stomach, and large intestine meridians. Warming middle-JIAO to promote qi, astringent intestines to stop diarrhea, used for spleen and stomach deficiency and cold, prolonged diarrhea, abdominal distension and pain, and vomiting due to lack of food. Modern pharmacological studies have shown that nutmeg has antibacterial, anti-inflammatory, sedative, and anti-tumor effects. According to previous studies, in addition to being rich in volatile oil and fatty o...
