[0064] 2.1 Selection of preparation conditions for the test product
[0065] 2.1.1, Selection of extraction solvent
[0066] Precisely weigh 3 parts of No. 5 Daluosan herbal medicine, 2.0g each, and place them in colorimetric tubes, respectively add 30% methanol, 60% methanol and pure methanol solution as extractants, and ultrasonically Treat for 40 minutes, let cool, weigh again, use 30% methanol, 60% methanol and pure methanol solution to make up the lost weight, shake well, filter to obtain the test solution. Under the conditions of the same detection method, measure its fingerprints respectively, and determine the best extractant by comparison; as figure 1 , figure 2 and image 3 Shown, under the same situation of other conditions, respectively use 30% methanol, 60% methanol and pure methanol to extract the chromatogram comparison of the test sample prepared by the cinnabar root of the same quality, the extractant is the cinnabar root spectrum of 60% methanol The peak...
Embodiment 1
[0081] Establish Daluosan Medicinal Materials
[0082] (1) Preparation of the test solution:
[0083] Accurately weigh 3.0g of Daluosan herbal powder and place it in a colorimetric tube, add 9mL of 60% methanol precisely, soak for 0.5h, ultrasonicate for 40min, let cool, make up the lost weight with 60% methanol solution, shake well, filter After that, the test solution was obtained;
[0084] (2) HPLC detection:
[0085] Draw the test solution obtained in the above step (1), inject it into a high-performance liquid chromatograph for high-performance liquid chromatography detection, and record the fingerprint within 50 min:
[0086] Wherein, the fingerprint chromatographic conditions are:
[0087] Adopt American AgiLent XDB-C18 chromatographic column (4.6×150mm, 5μm), mobile phase is acetonitrile-water system; adopt gradient elution method: 0min→10min→20min→30min→40min→50min, acetonitrile 45%→50%→55 %→55%→60%→63%; the detection wavelength is 280nm, the flow rate is 0.8mL / mi...
