Problems solved by technology
The established fingerprints of forsythia in China are mainly high-performance liquid chromatography fingerprints, and the index components of the research focus on forsythin and organic acids. No detection method has been established to reflect the characteristics of all chemical components and the content of active ingredients in forsythia. The object of nonlinear fingerprint detection is all the chemical components in Chinese herbal medicines

Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0027] A, establish the non-linear fingerprint of forsythia chemical constituents:
[0028] Five batches of Forsythia forsythia from Shaanxi were used as standard samples to establish nonlinear fingerprints of its chemical composition.
[0029] Instruments used: Metrohm 204N electrochemical workstation, HH-501 super constant temperature water bath, 85-2A digital constant temperature magnetic stirrer, 213 metal platinum electrode, 217 calomel electrode; chemical oscillation reaction is under continuous stirring In a jacketed reactor, open the super constant temperature water bath, adjust the temperature at (310±0.05)K, add 1.0g forsythia, 10ml 0.2mol / L KBr, 10ml 4.0mol / L H 2 SO 4 , 5ml0.04mol / LMnSO 4 , 5ml0.4mol / L CH 2 (COOH) 2 , The solution is placed in a jacketed reactor, and the reactor cover with a thermometer, a 213-type metal platinum electrode and...

Abstract
The invention discloses a nonlinear finger-print detection method for traditional Chinese medicine fructus forsythiae. The method comprises the following steps: A) establishing a nonlinear finger-print of the chemical component of fructus forsythiae, taking fructus forsythiae produced in same place and in same brand as a standard sample and establishing the nonlinear finger-print of the chemical component through chemical oscillation reaction; B) detecting the sample, taking a to-be-detected fructus forsythiae sample, detecting under the same condition of the standard sample, acquiring the finger-print of the detected sample, directly observing the two finger-prints and taking Origin software analysis as determining basis; C) viewing reproducibility, taking the to-be-detected fructus forsythiae sample and determining the finger-print thereof, wherein various characteristic parameters RSD of the detected nonlinear finger-print are less than 3%, so that the method has excellent reproducibility.
Description
technical field [0001] The invention relates to a detection method, in particular to a non-linear fingerprint detection method of traditional Chinese medicine forsythia. Background technique [0002] Forsythia suspense (Forsythia suspense) is the fruit of the Oleaceae shrub plant Forsythia, mainly produced in Shaanxi, Shanxi, Hebei and other places in China; harvested in autumn when the fruit is first ripe and the color is green; remove impurities, steam and dry , commonly known as "Qingqiao"; the ripe fruit is harvested, dried in the sun, and impurities are removed, commonly known as "Old Qiao". Chemical composition of forsythia: forsythol, oleanolic acid, 6,7-dimethoxycoumarin, sterols, betulinic acid, phillyrin, Forsythin (phillygenin), pinoresinol (pinoresinol), arctiin, arctigenin, flavonol glycosides, epiforsythin alcohol, rutin, betulinic acid, pinene, geranial, etc., have exogenous Evacuating wind-heat, internal heat-clearing and detoxifying medicine, often used fo...
