Abstract

The invention discloses an ultrasonic extraction method of active ingredients of cistanche tubulosa. The method comprises the following steps: (1) grinding fresh cistanche tubulosa into powder, adding water, adding ascorbic acid, and uniformly stirring and mixing; (2) adding ethanol into the product obtained in the step (1), then placing at room temperature, extracting, carrying out filter pressing, and collecting an extracting solution; (3) adding an ionic surfactant into the extracting solution, stirring, then adding diallyl ether and a catalyst, and reacting; (4) adjusting the pH value of the product obtained in the step (2) to 1-3, stirring, standing, and centrifuging; adjusting the pH value to 7-8, adding ozone to react, and concentrating the extracting solution under reduced pressure; and (5) adding the extracting solution into the extracting solution for extraction, and then performing vacuum concentration and drying. The method can effectively reduce the loss of effective components in the extraction process of cistanche tubulosa.

Description

technical field [0001] The invention belongs to the technical field of compound extraction and preparation, and in particular relates to an ultrasonic extraction method for active ingredients of Cistanche tuberose. Background technique [0002] Herba Cistanches (Herba Cistanches) is a well-known traditional tonic Chinese medicine. The Cistanche deserticola recorded in the 2005 edition of "Chinese Pharmacopoeia" is the dry fleshy stem with scaly leaves of Cistanche deserticola Y.C.Ma and Cistanche deserticola (Schrenk) R.Wight. "Shen Nong's Materia Medica" states: Cistanche "maintains the five labors and seven injuries. It is because the fire is weak and cannot produce soil, and it is not the root of the Qi. In the treatment of women's diseases, salty can soften the hardness and remove the blood. Cistanche stops the discharge of essence Drowning, remove the heat carbuncle in the stem, because it can guide the fire of asthenia, and the elderly are dry and stagnant, so it is b...
