Examples
experiment example 1
[0114] Experimental example 1: limit check of aconitine
[0115] 1. Instruments, reagents and test samples
[0116] Instruments: L-2100 Hitachi High Performance Liquid Chromatograph; AuW220D Shimadzu Electronic Analytical Balance.
[0117] Reference substance: aconitine reference substance (National Institute for the Control of Pharmaceutical and Biological Products) batch number: MUST-11031101.
[0118] Sample: Erwuwei Feibing Capsules (provided by Qinghai Jinhe Tibetan Medicine Co., Ltd.), batch numbers: 20110901, 20110902, 20110903.
[0119] 2. Selection of detection wavelength
[0120] Take aconitine reference substance solution and scan in the wavelength range of 190~400nm. Aconitine has maximum absorption at 235nm wavelength, so 235nm is selected as the detection wavelength according to the ultraviolet absorption spectrum.
[0121] 3. Mobile phase selection
[0122] The study found that aconitine can achieve good chromatographic separation effect when the methanol-wa...

[0168] Experimental Example 2: Content Determination Experiment of Hydroxysafflower Yellow A
[0169] 1. Instruments, reagents and test samples
[0170] Instrument: L-2100 Hitachi high performance liquid chromatograph; Shimadzu AuW220D electronic balance.
[0171] Reference substance: hydroxysafflower yellow A reference substance (National Institute for the Identification of Pharmaceutical and Biological Products), batch number: 111637-200905.
[0172] Sample: Erwuwei Feibing Capsules (provided by Qinghai Jinhe Tibetan Medicine Co., Ltd.), batch numbers: 20110901, 20110902, 20110903.
[0173] 2. Selection of detection wavelength
[0174] Take hydroxysafflower yellow A reference substance solution and scan in the wavelength range of 190~500nm. Hydroxysafflower yellow A has the maximum absorption at 403nm wavelength, so 403nm is selected as the detection wavelength according to the ultraviolet absorption spectrum.
[0175] 3. Mobile phase selection
[0176] The study found t...
experiment example 3
[0221] Experimental Example 3: Content Determination Experiment of Swertiamarin
[0222] 1. Instruments, reagents and test samples
[0223] Instrument: L-2100 Hitachi high performance liquid chromatograph; Shimadzu AuW220D electronic balance.
[0224] Reference substance: swertiamarin reference substance (National Institute for the Identification of Pharmaceutical and Biological Products), batch number: 0785-200203.
[0225] Sample: Erwuwei Feibing Capsules (provided by Qinghai Jinhe Tibetan Medicine Co., Ltd.), batch numbers: 20110901, 20110902, 20110903.
[0226] 2. Selection of detection wavelength
[0227] Take the swertiamarin reference substance solution and scan it in the wavelength range of 190~400nm. The swertiamarin has the maximum absorption at the wavelength of 243nm, so 243nm is selected as the detection wavelength according to the ultraviolet absorption spectrum.
[0228] 3. Mobile phase selection
[0229] The study found that swertiamarin can achieve good ch...
