Method for simultaneously preparing rare ginsenoside and grease unsaponifiable matter

Abstract

The invention, which belongs to the field of ginseng extract preparation methods, provides a method for simultaneously preparing rare ginsenoside and a grease unsaponifiable matter. The method comprises the following steps: processing dried ginseng into powder, adding petroleum ether, sodium hydroxide, n-butyl alcohol, ethanol and water, and performing extracting by using a stirring device; afterextraction finishing, performing standing, taking an upper-layer solution, and performing concentrating under a reduced pressure or normal pressure to obtain a ginseng grease unsaponifiable matter; taking a lower-layer solution, performing concentrating, performing treatment with a macroporous resin column, performing eluting with water until an ethanol eluent is colorless, clear and transparent,performing eluting with an ethanol solution until the ethanol eluent is colorless, clear and transparent, collecting the ethanol eluent, recovering ethanol, and performing drying to obtain the dry extract-like rare ginsenoside. The method can be used for preparing rare ginsenoside and a grease unsaponifiable matter at the same time and is convenient, efficient, and easy to operate; the cost is low; and the utilization rate of ginseng is increased. The development and utilization requirements in the fields of medicines, foods and chemical engineering are met. The method for simultaneously preparing rare ginsenoside and a grease unsaponifiable matter has the great application and development values.

Description

technical field [0001] The invention belongs to the field of preparation methods of ginseng extracts, in particular to a method for simultaneously preparing rare ginseng saponins and oil unsaponifiables. Background technique [0002] Panax ginseng is the dried root of Panax ginseng C.A.Mey. Nature and flavor: sweet, slightly bitter, warm and flat. Return spleen, lung meridian, heart meridian. Invigorating qi, solidifying, promoting body fluid, calming the nerves, and improving intelligence. Indications: Deficiency of the body, cold limbs, slight pulse, spleen deficiency, lack of food, lung deficiency, wheezing and coughing, thirsty body fluid wound, internal heat and thirst, chronic illness and weakness, palpitations and insomnia, impotence and uterine cold; heart failure, cardiogenic shock. It is used for shortness of breath, palpitation, forgetfulness, excessive thirst and sweating, lack of appetite and weakness, all acute and chronic diseases and shock and collapse cau...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned technology has the following defects: (1) when the existing method obtains the unsaponifiable matter in the oil, the oil is mostly used as the starting research material; After six steps of oil extraction from raw materials, concentration, oil preparation, saponification, extraction, and washing, the steps are relatively independent, the operation is cumbersome, and wastes manpower and material resources.

(4) There is no report on the simultaneous preparation of oil unsaponifiables and ginsenosides
