Take 1g of this product powder, add 25ml of methanol, ultrasonic treatment for 30 minutes, filter, concentrate the filtrate to dryness, add 1ml of methanol to the residue to dissolve, and use it as the test solution. Take another rosmarinic acid reference substance, add methanol to make a solution containing 0.2mg per 1ml, and use it as the reference substance solution. According to the thin layer chromatography (Appendix VI B) test, draw 2 μl of each of the above two solutions, place them on the same silica gel G thin layer plate, and use cyclohexane ethyl acetate formic acid (3:3:0.2) as the developer. Agent, unfold, take out, dry, and inspect under UV light (365nm). In the chromatogram of the test product, the same fluorescent spots appear at the corresponding positions of the chromatogram of the reference substance. 11.5 Inspection 11.5.1 Moisture content
shall not exceed 9.0% (Appendix IX H First Method). 11.5.2 Total ash content
shall not exceed 5.0 (Appendix IX K). 11.6 Content determination
Avoid light operation. Determine according to high performance liquid chromatography (Appendix VI D). 11.6.1 Chromatographic conditions and system suitability test
Use octadecylsilane bonded silica gel as the filler; use methanol 0.1 formic acid solution (38:62) as the mobile phase; the detection wavelength is 330nm. The number of theoretical plates should not be less than 3000 based on the rosmarinic acid peak. 11.6.2 Preparation of reference substance solution
Take an appropriate amount of rosmarinic acid reference substance, weigh it accurately, add 60% acetone to make a solution containing 40μg per 1ml, and you have it. 11.6.3 Preparation of test solution
Take about 0.5g of this product powder (passed through No. 3 sieve), weigh it accurately, place it in a stoppered Erlenmeyer flask, add 25ml of 60 acetone accurately, and seal it tightly. , weigh it, conduct ultrasonic treatment (power 250W, frequency 40kHz) for 30 minutes, weigh it again, use 60% acetone to make up for the lost weight, shake well, and filter. Precisely measure the remaining filtrate to get it. 11.6.4 Determination method
Precisely absorb 10?l of the reference solution and 5-20?l of the test solution, inject them into the liquid chromatograph, and measure.
This product shall contain no less than 0.10% rosmarinic acid (C18H16O8) as a dry product. 11.7 Perilla stem decoction pieces 11.7.1 Processing
