Problems solved by technology

At present, a variety of saponins in Jasmine Japonica have been isolated and identified, but most of these separation and extraction methods belong to laboratory research methods. The method is complicated, the cost is high, and the yield of the isolated saponins is low. It is not suitable for industrial production, and the content of ingredients in the extract is not clear, which is not conducive to the application in pharmaceutical and therapeutic fields
[0003] Our laboratory has been engaged in the separation, extraction and research of the medicinal components of Limonosa japonica for many years. In our previous application 200610039294.4, we disclosed the total saponin extract extracted from Lonicerae argentina. The total saponin content in this extract is 50% -90%, wherein Lonicera cinerea Lonicera saponin B: Lonicera cinerea Lonicerae saponin A=12~6:1, also discloses its preparation method and use for the prevention and treatment of liver cancer, in our another The application 200710023243.7 discloses the preparation method of the monomeric component Lonicera tomentosa saponin B and its application in the treatment of liver cancer, breast cancer and cervical cancer. However, the yield of the extraction method in the above application is still relatively low. The disclosed treatment limited types of cancer

Embodiment 1

[0027]The flowers and buds of Lonicerae pilosula are extracted with 8 times the volume of 60% ethanol at 90 degrees Celsius, and the solvent is recovered to one-fifth of the original volume of the extract, cooled to 0 degrees Celsius, filtered to obtain the filtrate, and the filtrate is added 8% KOH was hydrolyzed at 80 degrees Celsius for 10 hours, extracted with n-butanol after cooling, and the n-butanol extract was back-extracted with an alkaline aqueous solution with a pH value of 13 saturated with n-butanol, and the n-butanol solution after back extraction was adjusted to pH The value is 7, and the n-butanol solution is reclaimed to obtain the Flos Lonicerae extract, after testing, by weight, wherein Lonicera tomentosa saponin B (hereinafter referred to as component a): Lonicera tomentosa saponin A (hereinafter referred to as group Part b): 3-O-α-L-rhamnopyranosyl (1-2)-α-L-arabinopyranosyl-hederidenin (hereinafter referred to as component c): 3-O- β-D-glucopyranosyl(1-4)...

Embodiment 2

[0029] Red gland honeysuckle flower and flower buds, use 10 times the volume of water, extract at 60 degrees Celsius, recover the solvent to one-sixth of the original volume of the extract, cool to 2 degrees Celsius, filter to obtain the filtrate, add 50% NaOH to the filtrate, and add 50% NaOH to the filtrate. It was hydrolyzed for 3 hours under Celsius, extracted with n-butanol after cooling, and the n-butanol extract was back-extracted with 0.1% NaOH aqueous solution saturated with n-butanol, and the pH value of the n-butanol solution after the back extraction was adjusted to 7, and the n-butanol solution was recovered. The butanol solution obtains the Flos Japonica extract, and after testing, by weight, component a: component b: component c: component d=42:9:10:1, and the total weight of the four ingredients It accounts for 62% of the extract, and the yield is 12%.

Embodiment 3

[0031] Red glandular honeysuckle flowers and flower buds and yellow-brown honeysuckle flowers and flower buds with a weight ratio of 1:1 are extracted with 3 times the volume of 100% methanol at room temperature, and the extract is recovered to a quarter of the original volume. Cool down to 4 degrees Celsius, filter to obtain the filtrate, add 0.5% KOH to the filtrate, hydrolyze it at 40 degrees Celsius for 10 hours, extract it with n-butanol, and extract the n-butanol extract with 0.8% KOH saturated with n-butanol. The final n-butanol solution is adjusted to a pH value of 7, and the n-butanol solution is recovered to obtain the Jasmine Japonica extract. After testing, by weight, component a: component b: component c: component d = 14:2:3:1 , and the total weight of the four components accounts for 74% of the extract, with a yield of 11%.
