Embodiment 1
[0076] (1) Preparation of asiaticoside reference substance solution
[0077] Accurately weigh 15 mg of asiaticoside, put it in a 10ml volumetric flask, add methanol to dissolve and dilute to the mark, shake well, as a stock solution of asiaticoside reference substance, concentration 1.4464mg / ml; accurately absorb the above-mentioned reference substance stock solution 1.2 ml, put it in a 10ml measuring flask, add methanol to make a reference substance solution of asiaticoside containing 0.1736mg per 1ml.
[0078] (2) Preparation of test solution
[0079] Take about 0.5g of Centella asiatica powder (passed through the No. 2 sieve), accurately weigh it, place it in a stoppered Erlenmeyer flask, accurately add 20ml of 80% methanol, weigh it, and ultrasonically treat it (power 210W, frequency 40kHz) for 30 minutes. Cool, weigh it again, add 80% methanol to make up the weight loss, shake well, filter, take the filtrate, and get it;
