Embodiment Construction

[0014] The present invention adopts the following technical solutions.

[0015] (1) Weigh schisandra alcohol A, schisandra alcohol B, and schisandra ester A reference substances in the same volumetric flask, add methanol to the mark, shake well, filter, and take the subsequent filtrate as mixed standard solution A; weigh schisandra A Put the reference substances of schisandrin, schisandrin B, and schisandrin C in the same volumetric flask, add methanol to the mark, shake well, filter, and take the subsequent filtrate as the mixed standard reference solution B.

[0016] (2) Take Schisandra chinensis, crush and grind it into powder, sieve it, weigh the powder, add it to 75% ethanol, weigh it, process it ultrasonically for 10-60 minutes, take it out, put it at room temperature, make up the missing weight with 75% ethanol, and shake well , filtered, and the filtrate was taken to obtain the test solution.

[0017] (3) Take the mixed standard reference solution A and B resp...

Abstract

The invention especially relates to a determination method for lignan content, belonging to the technical field of content determination. The method provided by the invention has the advantages of high efficiency and simple and flexible operation. The method comprises the following steps: weighing and putting schisandrol A, schisandrol B and a schisandrol A reference substance in a same volumetric flask, adding methanol to a scale, carrying out shaking up and filtration and taking a subsequent filtrate as a mixed standard reference substance solution A; weighing and putting deoxyschizandrin, schisandrin B, a schisandrin C control product in a same volumetric flask, adding methanol to a scale, carrying out shaking up and filtration and taking a subsequent filtrate as a mixed standard reference substance solution B; weighing Chinese magnoliavine fruit, smashing and grinding the Chinese magnoliavine fruit, then carrying out sieving, weighing the obtained powder, adding 75% alcohol, weighing the weight, carrying out ultrasonic treatment for 10 to 60 min, taking an obtained substance out, cooling the substance to room temperature, adding 75% ethanol to compensate for lost weight, carrying out shaking up and filtration and taking a subsequent filtrate so as to obtain a to-be-determined sample solution; and respectively weighing the mixed standard reference substance solutions A and B, respectively diluting the solutions 1 time and respectively injecting the solutions into a liquid chromatograph.

Description

Technical field [0001] The present invention is a technical field of content measurement, especially the method of lignin content measurement. Background technique [0002] Schisandra is started in "Shennong Materia Medica". It is warm, sour, sweet, and returns to the lungs, heart, and kidney meridians. It is a commonly used Chinese medicine in my country. The 2010 version of the Pharmacopoeia of the People's Republic of China is collected. The source of the main effect is to nourish the kidneys, nourish the kidneys, condense sweat, astringent essence to stop diarrhea, and peace. [0003] The vine stems of the folk five -flavored subclacium plants in my country are also used for medicinal stems.According to reports, the fruits and rattan stems of Schisandraceae contain ingredients of lignin. Lignanin is the main physiological activity ingredients of Schisite Subcotae plants.The role of liver protection.The ingredients in Schisandra are mainly deoxyschisandrin, Schizandrin B, Schi...
