Embodiment 1

[0029] A method for increasing the content of notoginseng saponin R1 in notoginseng, comprising spraying the notoginseng plants with a salicylic acid solution before harvesting the notoginseng.

[0030] Wherein, in the method for increasing the content of notoginseng saponin R1 in Panax notoginseng, the solubility of the salicylic acid solution is 0.3-1.3 mmol / L.

[0031] Wherein, in the method for increasing the content of notoginseng saponin R1 in notoginseng, the notoginseng plant is sprayed with the salicylic acid solution 30-70 days before the harvest of notoginseng.

[0032] Wherein, in the method for increasing the content of notoginseng saponin R1 in notoginseng, the notoginseng plant is a notoginseng plant cultivated for 2-3 years.

[0033] Wherein, in the method for increasing the content of notoginseng saponin R1 in notoginseng, the salicylic acid solution is sprayed on the leaf surface of the notoginseng plant.

[0034] Wherein, in the method for increasing the co...

Embodiment 2

[0043] In January 2014, in Wuping Town, Jingxi County, Guangxi, the inventor planted the annual seedlings of Panax notoginseng in the soil, and cultivated them according to conventional cultivation methods.

[0044] Pre-harvest treatment was carried out in September 2014. The notoginseng plants were randomly divided into 6 groups: control group A, experimental group A1, experimental group A2, experimental group A3, experimental group A4 and experimental group A5, with 30 plants in each group.

[0045] Control group A sprayed Panax notoginseng plants with water before harvesting, sprayed once every 10 days, and sprayed three times in total.

[0046] The experimental group A1 was evenly sprayed on the surface of the leaves of Panax notoginseng with a salicylic acid solution at a concentration of 0.1 mmol / L before harvesting, once every 10 days, and sprayed three times in total.

[0047] The experimental group A2 was evenly sprayed on the surface of Panax notoginseng leaves with...

Embodiment 3

[0058] In January 2013, in Wuping Town, Jingxi County, Guangxi, the inventor planted the annual seedlings of Panax notoginseng in the soil, and cultivated them according to conventional cultivation methods.

[0059] Pre-harvest treatment was carried out in September 2014. The notoginseng plants were randomly divided into 6 groups: control group B, experimental group B1, experimental group B2, experimental group B3, experimental group B4 and experimental group B5, with 30 plants in each group.

[0060] Control group B sprayed Panax notoginseng plants with water before harvesting, once every 10 days, and sprayed three times in total.

[0061] The experimental group B1 was evenly sprayed on the surface of Panax notoginseng leaves with a salicylic acid solution at a concentration of 0.1 mmol / L before harvesting, once every 10 days, and sprayed three times in total.

[0062] The experimental group B2 was evenly sprayed on the surface of the leaves of Panax notoginseng with a salic...

Abstract

The invention discloses a method for increasing the content of notoginsenoside R1 in panax notoginseng. Before the panax notoginseng is harvested, a salicylic acid solution is sprayed to panax notoginseng plants. According to the method, due to the fact that the salicylic acid solution is used for processing the panax notoginseng plants before the panax notoginseng is harvested, the content of the notoginsenoside R1 in the panax notoginseng is increased, the method can be used on a large scale in a conventional panax notoginseng cultivating method so that the notoginsenoside R1 can be industrially produced on a large scale, and the requirement of the market for the notoginsenoside R1 is met.

Description

technical field [0001] The invention relates to the field of notoginseng cultivation. More specifically, the present invention relates to a method for increasing the content of notoginseng saponin R1 in Panax notoginseng. Background technique [0002] Panax notoginseng is the dried root of Panax notoginseng (Burk.) F.H.chen, an Araliaceae plant. It is a traditional precious medicinal material in my country. It has the effects of stopping bleeding, dissipating blood stasis, reducing swelling, and relieving pain. It is made of Panax notoginseng or total saponins The preparations are widely used clinically in the treatment of cardiovascular and cerebrovascular diseases. Notoginseng saponin R1 belongs to the protopanaxatriol type saponin, which is a unique chemical component of notoginseng, and is also the most representative characteristic compound of notoginseng. Previous studies have confirmed that notoginseng saponin R1 has a good effect on preventing and treating vascular e...
