Ginseng extract is extracted and refined from the roots, stems and leaves of the pannax plant ginseng. It is rich in 18 types of ginseng monomer saponins. It is soluble in water at 80°C and easily soluble in ethanol.
Cut ginseng into thick slices, add water and decoct twice, 2 hours for the first time, is 1.5 hours for the second time . The decoction is filtered and combined, passing through a D101 macroporous adsorption resin column, and eluted with water till colorless, then it is eluted with 60% ethanol, and the 60% ethanol eluate is collected. The filtrate is concentrated to a clear cream with a relative density of 1.06~1.08 (80℃）, dried and crushed to get finished powder.

Content of Ginsenoside
Below is the complete method to assay the Ginsenoside of ginsenoside. That is also the compliance of the lab test within our factory.
Filler: octadecylsilane-bonded silica gel
column length is 25cm, inner diameter is 4.6mm, particle size is 5 m, carbon loading is 11%
phase A: acetonitrile
phase B:0.1% phosphoric acid
column temperature: 30℃;
detection wavelength: 203 nm
Preparation of the reference solution Take appropriate amounts of ginsenoside Rg1 reference substance, ginsenoside Re reference substance and ginsenoside Rd reference substance, accurately weighed, and add methanol to make each 1ml containing ginsenoside Rg1 0.3mg, ginsenoside Re 0. 5mg and A solution of 0.2mg ginsenoside Rd is available.
Preparation of the test solution: Take 30mg of this product, accurately weigh it, place it in a 10ml bottle, add methanol ultrasonic treatment to dissolve and dilute to the mark, shake well, filter, and take the additional filtrate to get it.
For the determination method, each 10 belg of the reference solution and the test solution are accurately drawn, injected into the liquid chromatograph, and measured, and the result is obtained.
There should be 7 characteristic peaks in the characteristic spectrum of the test product, of which 3 peaks should have the same retention time as the corresponding reference peak. 3 The peak corresponding to the ginsenoside Rd reference peak is the S peak. Calculate the characteristic peaks 3 to 7 Relative retention time, the relative retention time should be within ±5% of the specified value, the specified value is * 0.84 (peak 3), 0.91 (peak 4), 0.93 (peak 5). 0.95 (Peak 6) .1.00 (Peak 7).
Relatively retention time
Preparation of reference substance solution
Take an appropriate amount of ginsenoside Re reference substance, accurately weigh it, and add methanol to make a solution containing 1 mg per 1 ml, then it is ready.
This product is contains 15%~25% ginsenoside calculated as the sum of ginsenoside Rg1 (C«H»O14), ginsenoside Re (C48H82O) and ginsenoside Rd (C48 H82O18), on dry basis.
Gingseng extract is mainly suitable for symptoms such as coronary heart disease, angina pectoris, slow heart rate, too fast, premature ventricular dysfunction, blood pressure disorders, neurasthenia, menopausal syndrome, excessive fatigue, post-illness, postpartum, postoperative physical weakness and other symptoms;
It can also enhance physical strength and treat cancer patients with low immune function caused by radiotherapy and chemotherapy; it has the effect of resisting cold and heat stress. At the same time, it has the functions of enhancing the vitality of human body surface cells and inhibiting aging.
