example 1

[0031] Example 1 Preparation of Taiwan Tianxian fruit extract sample

[0032] This example uses Tianxian fruit produced in Taiwan as the raw material, and the Taiwan Tianxian fruit used has passed the "Taiwan Tianxian fruit pesticide and heavy metal limit standard value".

[0033] Take the Taiwan Tianxian fruit (purchased with dry materials), take the appearance of part of the roots, part of the flakes smaller than 4 cm, and grind to pass through a 30-hole sieve. Test the moisture content according to the operating instructions of the infrared moisture analyzer, and control the moisture content of the Taiwan Tianxian fruit sample to be less than 10%.

[0034] Take 50 grams of Taiwan Tianxian fruit with a moisture content of less than 10% in a 1-liter four-necked flat-bottomed flask, add 500 ml of 100% methanol, heat and reflux for 4 hours, centrifuge and filter, quantify the filtrate volume (V1) and take 1 One milliliter of filtrate was subjected to subsequent HPLC analysis. Add 50...

[0036] Example 2 Preparation of standard and blank solution

[0037] Weigh 5mg of apigenin and place it in a 2mL volumetric flask, add a little methanol and shake to dissolve it, and then add methanol to the mark to make the standard concentration 2500μg / mL. Then, according to the volume indicated in Table 2, add methanol to serially dilute the standards of different concentrations:

[0038] Table 2 Apigenin standard concentration

[0039] Concentration (μg / mL); ppm 0 100 200 300 400 500

[0040] 2500μg / mL standard (mL) 0 0.08 0.16 0.24 0.32 0.4

[0041] Methanol (mL) 2 1.92 1.84 1.76 1.68 1.6

[0042] The above-mentioned standard solution of different concentrations was analyzed by HPLC, and the concentration of the standard was taken as the abscissa value and the peak area value was the ordinate value for linear regression analysis to obtain an XY line passing through the origin. When the correlation coefficient of the standard curve (R2) is 0.999 ~1, can be used. In this embodiment...

[0044] HPLC analysis equipment and methods

[0045] material

[0046] All solvents and reagents are HPLC grade (purchased from Merck). Apigenin (purchased from Sigma) is a standard product of the index component of Tianxian fruit (99% HPLC calibration).

[0047] instrument

[0048] American Waters (WATERS) high performance liquid chromatography system (LC-Module I). The analytical balance can read up to 0.1 mg.

[0049] HPLC analysis conditions
