Embodiment Construction

[0010] Take Caragana microphylla Lam or C. intermedia Kuanget H.C. Fu as an example.

[0011] Crush the whole flowers of Caragana microphylla (or Caragana intermedia) that are naturally air-dried (or dried at a constant temperature of 50°C or 60°C), and pass through a 40-mesh (or 50-mesh or 60-mesh) sieve; weigh the sieved dry powder 1 kg, add 6-25 liters (optional 10, 15, 20 liters) 45% (or 50% or 55% or 60% or 65%) ethanol solution, 50 ℃ (or 45 ℃ or 55 ℃ or 60 ℃ or Stir and soak for 3 hours at 65° C., filter, add 4-12 liters of filter residue (optional 5, 8, 10 liters) 45% (or 50% or 55% or 60% or 65%) ethanol solution, 50 °C (or 45 °C or 55 °C or 60 °C or 65 °C) and soaked for 1 hour, extracted twice, and combined the three filtrates to obtain the upper column liquid; the upper column liquid was reduced at 60 °C (55 °C or 65 °C). Press and concentrate to reclaim ethanol until the upper column liquid has no alcohol smell; then the upper column liquid is separated through a ...

Abstract

A process for extracting the general flavone from the whole flower of Peashrub plant includes preparing liquid extract from said flower, separating by separating column, eluting, and concentrating. The process for preparing liquid extract from said flower is also disclosed.

Description

technical field [0001] The invention relates to a method for extracting total flavone products from plants, in particular to a method for extracting total flavone products from whole flowers of Caragana plants. Background technique [0002] Flavonoids are a class of yellow pigments that widely exist in plants, and they exhibit a variety of physiological functions, including cardiovascular function, antioxidant function, antiarrhythmic function, anti-tumor and anti-cancer function, antitussive and antiasthmatic function, Antibacterial and antiviral functions, hypotensive and blood lipid functions, hormone-like functions and immune regulation functions, etc., are widely used in the food and pharmaceutical industries. [0003] At present, the extraction industry of flavonoids is mainly faced with the following problems: 1. The plant raw materials for large-scale extraction are mainly concentrated in ginkgo leaves, tartary buckwheat seeds, soybeans, etc. Among them, the total f...
