Abstract

The oriental water plantain sterol is extracted through supercritical CO2 fluid extraction of oriental water plantain, and the extract product contains oriental water plantain alcohol monoacetate B not less than 3.5 % and total sterol content measured through spectrophotometric method not less than 50 %. The extract product is further produced various product forms with the functions of resisting fatty liver, hypertension and hyperlipemia. At the same time, the efficient liquid phase method of determining the content of oriental water plantain alcohol monoacetate B in material and extract and the spectrophotometric method of determining the content of total sterol in material and extract are also provided for the quality control.

Description

technical field [0001] The invention relates to alisma sterol extract and a preparation method thereof, a quality control method of alisma alisma raw material and extract. Background technique [0002] Alisma has anti-fatty liver, high blood pressure and hyperlipidemia effects, and its active substances are mainly sterols. Usually extract sterols with ethanol, the method is: take Alisma powder (through 20 mesh sieve), extract with reflux of 90% ethanol, recover ethanol, obtain immersion oil, the yield is about 6%. Put the immersion oil on a macroporous resin (AB-8) column, and elute with water, 40% ethanol, and 95% ethanol respectively, and the yields of each part are 27.4%, 5.7%, and 34.9%, respectively. The part eluting with ethanol is the refined product of Alisma macroporous resin. Measure the total sterol content with colorimetry, based on Alisma B monoacetate, the total sterol content in the refined product is 10%, because the total sterol content in the refined prod...
