Embodiment 2
[0179] Embodiment 2 Preparation of Guizhi Shaoyao Zhimu Decoction Composition and Preparation of Need Testing Solution
[0180] Weigh the following decoction pieces by weight: Guizhi 12g, Radix Paeoniae Alba 9g, Anemarrhena 12g, Ephedra 6g, Paofupian 6g, Fangfeng 12g, Ginger 15g, Atractylodes Rhizoma Atractylodes Rhizome 5g, Radix Glycyrrhizae 6g; Put Jiuwei decoction pieces in a 5L casserole , add 1400ml of water, soak for 30 minutes, cover, add to boil, keep slightly boiling until the decoction is 400ml, filter it with a 350-mesh filter cloth while it is hot, concentrate the filtrate to an appropriate amount under reduced pressure, freeze-dry, pulverize, and mix well to obtain Composition of Guizhi Shaoyao Zhimu Decoction.
[0181] Take about 0.18g of the above-mentioned Guizhi Shaoyao Zhimu Decoction composition, accurately weigh it, put it in a 10ml measuring bottle, add an appropriate amount of water, and perform ultrasonic treatment for 10-30 minutes (power 250W, frequen...
Embodiment 3
[0182] The investigation of embodiment 3 fingerprint chromatographic conditions
[0183] (1) Selection of detection wavelength
[0184] Use octadecylsilane bonded silica gel as filler; use acetonitrile as mobile phase A and 0.1% phosphoric acid solution as mobile phase B, and carry out gradient elution as specified in the table below; flow rate 0.25ml / ml, column temperature: 30°C.
[0185] Table 1: Mobile Phase Gradient Program for Fingerprinting
[0186]
[0187] Adopt diode array detector to carry out full-wavelength detection to the need testing solution of embodiment 2, according to the three-dimensional graph of collection (see figure 1 ), and simultaneously collect the spectra at 210nm, 230nm, 254nm, 270nm, and 280nm wavelengths (see figure 2 ). Comprehensive investigation, compared with other wavelengths, the composition of Guizhi Shaoyao Zhimu Decoction has the largest peak information at 210nm wavelength, which can characterize the components of ephedrine hydr...
