Method for increasing contents of effective components including polysaccharides and total flavonoids in astragalus mongholicus

Abstract

The invention discloses a method for increasing the contents of effective components including polysaccharides and total flavonoids in astragalus mongholicus. The method is realized by applying indoleacetic acid and / or paclobutrazol. Specifically, the highest astragalus polysaccharide content is obtained when 400 mg / L of paclobutrazol is applied, and the content of astragalus root polysaccharide is in an ascending trend when the application amount of indoleacetic acid is in a range of 100 mg / L to 200 mg / L, is in a descending trend the application amount of indoleacetic acid is in a range of 200 mg / L to 400 mg / L, and is the highest when the application amount of indoleacetic acid is 200 mg / L; the highest flavonoid content is obtained when 400 mg / L of paclobutrazol is applied; and in treatment with an indoleacetic acid growth regulator, the flavonoid content is in an ascending trend when the application amount of the indoleacetic acid growth regulator is in a range of 100 mg / L to 200 mg / L, is in a descending trend when the application amount of the indoleacetic acid growth regulator is in a range of 200 mg / L to 400 mg / L, and reaches the maximum value when the application amount of the indoleacetic acid growth regulator is 200 mg / L. The invention provides a novel method for increasing the contents of effective components including polysaccharides and total flavonoids in astragalusmongholicus, and the method has a promoting effect on the yield of astragalus mongholicus.

Description

technical field [0001] The invention relates to the technical field of astragalus planting, in particular to a method for increasing polysaccharides and total flavonoids as effective components of astragalus. Background technique [0002] Astragalus ( Astragalus mongholicus Bunge), a leguminous plant, one of the commonly used traditional Chinese medicines, is the root of the leguminous plant Astragalus mongolica or Astragalus membranaceus. It is mainly produced in Inner Mongolia, Shanxi, Heilongjiang and other places in China. Excavated in spring and autumn, dried in the sun, sliced, used raw or roasted with honey. Sweet in nature, slightly warm, returns lung, spleen, liver, kidney meridian. It has the effects of inducing diuretic toxin, evacuating pus, astringing sores and promoting granulation. The main components of Astragalus membranaceus are total flavonoids and polysaccharides. Astragalus polysaccharides are immune enhancers or regulators, and have anti-virus, an...
