Embodiment 1
[0039] A kind of method for quickly measuring the content of Radix Notoginseng medicinal material of the present embodiment, it is measured according to the following steps:
[0040] (1) Preparation of test solution
[0041]Accurately weigh 50.01g of Panax notoginseng crude powder as the test sample 1, add 75% ethanol and heat and extract three times respectively, the volume of the 75% ethanol added in the three heating extractions is 250ml, 100ml, 100ml successively, the temperature of each heating extraction The temperature is 70°C, and the heating and extraction time is 1h each time. The three extracts are filtered with gauze to obtain the filtrate, the filtrates are combined and 75% ethanol is added to make the volume to 500ml, shake well, and the filtrate is obtained by filtration. Add methanol to 5ml of filtrate and dilute to 50ml to prepare the test solution;
[0042] (2) Preparation of reference substance solution
[0043] Precisely weigh ginsenoside R g1 Reference ...
Embodiment 2
[0069] A kind of method for quickly measuring the content of Radix Notoginseng medicinal material of the present embodiment, it is measured according to the following steps:
[0070] (1) Preparation of test solution
[0071] Accurately weigh 50.20g of Panax notoginseng crude powder as the test sample 1, add 75% ethanol and heat and extract three times respectively, the volume of the 75% ethanol added in the three heating extractions is 250ml, 100ml, 100ml in sequence, and the temperature of each heating extraction The temperature is 70°C, and the heating and extraction time is 1h each time. The three extracts are filtered with gauze to obtain the filtrate, the filtrates are combined and 75% ethanol is added to make the volume to 500ml, shake well, and the filtrate is obtained by filtration. Add methanol to 5ml of filtrate and dilute to 50ml to prepare the test solution;
