Embodiment 1
[0031] The contents of rutin naringin, naringin, hesperidin and neohesperidin in Fructus Aurantii were determined by HPLC.
[0032] Preparation of the test solution: Weigh 0.5g of Fructus Fructus decoction powder (passed through No. 2 sieve), weigh it accurately, put it in a 100mL round bottom flask, add 50mL of methanol precisely, weigh it, heat and reflux for 1.5h (75°C) , let it cool, weighed, made up for the lost weight with methanol, shaken well, filtered into a 50mL volumetric flask, filtered through a 0.22μm filter membrane, and took the subsequent filtrate to obtain the final product.
[0033] Preparation of the reference solution: take appropriate amount of rutin naringin, naringin, hesperidin and neohesperidin respectively, accurately weigh them, add methanol to dissolve in a 10mL measuring bottle, and dilute to the scale to make each 1mL containing Rutina naringin 0.283mg / mL, naringin 1.074mg / mL, hesperidin 0.210mg / mL, neohesperidin 1.001mg / mL, ready to use.

Embodiment 2
[0041] The medicinal material of Fructus Aurantii is hard and needs to be moistened in order to facilitate cutting. Take 5kg of washed Fructus Fructus Fructus, put them in the medicine moistening machine respectively, vacuumize for 6 minutes, and moisten at 30°C, 45°C, 50°C, 60°C for 20 minutes, cut into thin slices (2mm), and blow dry at 55°C for 2 At the same time, sieve to remove the broken pulp core, and then get the decoction pieces moistened at different temperatures. The analysis method of Example 1 was used to measure the contents of rutin naringin, naringin, hesperidin and neohesperidin in each sample respectively, and the results are shown in Table 1 below.
[0042] Table 1 Comparison of the main components of Fructus Aurantii decoction pieces at different infiltration temperatures (mg.g -1 )
[0043] Infiltration temperature rutin naringin Naringin Hesperidin neohesperidin Sum of measurable ingredients 30℃ 3.1943 59.6967 2.7001 56.6108 ...
Embodiment 3
[0046] Take 5kg of washed Fructus Fructus Fructus, put it in a moistening machine at 45°C for 20 minutes, cut into 1mm, 1.5mm, and 2mm thick slices, and dry it with air at 55°C for 2 hours. The contents of main components rutin naringin, naringin, hesperidin and neohesperidin in each sample were determined, and the results are shown in Table 2 below.
[0047] Table 2 Comparison of the contents of main components in different slice thicknesses (mg.g -1 )
[0048] slice thickness rutin naringin Naringin Hesperidin neohesperidin total flavonoids 1mm 3.2111 61.4133 2.4431 56.4902 123.5577 1.5mm 3.2429 61.0987 2.5003 55.9063 122.7483 2mm 3.5331 65.5954 2.5624 58.6750 130.3659
[0049] It can be seen from the above table 2 that when the slice thickness is 2mm, the content of each main active ingredient is relatively high.
