Problems solved by technology

[0003] At present, various dosage forms such as Bupleurum Dropping Pills are on the market, but most of them use saikosaponin as the main component. For the main active ingredient volatile oil of Bupleuri, the existing technology to dissolve it in the water phase mostly uses methods such as adding co-solvents , the dissolution effect is poor, and it is unstable after dissolution

Abstract

The present invention relates to a bupleurum volatile oil inclusion method. It is characterized by that after the bupleurum volatile oil is obtained by adopting water vapour distillation process, under the condition of ultrasonic treatment said invention utilizes HP-beta-CD to make inclusion of bupleurum volatile oil. The invented included bupleurum volatile oil can be completely dissolved in water and is very stable.

Description

Technical field: [0001] The invention relates to a method for clathrate bupleurum volatile oil by using HP-β-CD. Background technique: [0002] Bupleurum is flat in nature, soothes the liver and relieves stagnation, reconciles and reduces fever, and elevates yang energy. Elevate the clear and lower the turbidity, harmonize the exterior and interior, reconcile Shaoyang, and clear away the evil heat of Shaoyang. Bupleurum is good at dispelling stagnation, it can soothe and regulate the qi of the liver and gallbladder, and it can also clear away the dampness and heat accumulated in it. Functional treatment of typhoid and stroke, Shaoyang disease, bitter mouth and dry throat, dizziness and deafness, coming and going of cold and heat, chest and hypochondrium pain fullness, silent reluctance to eat and drink, upset and happy vomiting or upset and not vomiting in the heart, or thirst, or pain, or abdominal pain Hardness, or palpitations, difficulty urinating, or not thirsty, slig...
