Embodiment 1
[0046] [Example 1] Content detection method of sarsaparilla water-soluble components
[0047] 1) Chromatographic conditions
[0048] Chromatographic column: YMCpackODS-AQ liquid chromatography column (4.6×250mm5μm); mobile phase: volume ratio 10:8:64 methanol-acetonitrile-0.2% phosphoric acid solution; detection wavelength: chlorogenic acid is 325nm, HeliciosideA is 283nm; column temperature : 35℃; flow rate: 1.0ml min -1 , the corresponding retention times of chlorogenic acid and HeliciosideA are 7.3min and 13min respectively;
[0049] 2) Preparation of the test solution
[0050] Take 1.5g of sarsaparilla powder, weigh it accurately, put it in a stoppered Erlenmeyer flask, accurately add 25ml of 80% methanol as the extraction solvent, seal it tightly, weigh it, extract it by ultrasonic for 45min (power 250W, frequency 40kHz), let it cool, Weigh the weight, use the extraction solvent to make up for the lost weight, shake well, filter, and take the filtrate to obtain the fin...
Embodiment 2
[0055] [Example 2] The content detection method of the water-soluble components of Sarsaparilla
[0056] The specific operation steps are the same as in Example 1, and the difference from Example 1 is that the extraction solvent in step 2) is 50% methanol.
Embodiment 3
[0057] [Example 3] Content detection method of Smilax sarsaparilla water-soluble components
[0058] The specific operation steps are the same as in Example 1, and the difference from Example 1 is that the extraction solvent in step 2) is ethanol.
