Embodiment 1
[0016] Detection method:
[0017] Determination of flavonoid content:
[0018] Flavonoid extraction: Weigh about 0.5g of dry sample, add 10ml of 70% ethanol to soak, shake intermittently for 6 hours at 70°C, filter with G3 sand core funnel, add 10ml of 70% ethanol to soak, and soak at 70°C Intermittent shaking for 6h, repeated 3 times. Combine the filtrate, dilute to 50ml, to be tested;
[0019] Determination of flavonoids: make standard curve: take 18 50ml volumetric flasks, draw 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34ml 100ug / L rutin solution (prepared in 30% ethanol), add 10ml 30% ethanol, 0.7ml 5% NaNO2, add 10% Al(NaNO3)3 after 5min, add 5ml 40%NaOH after 6min, mix well, use Dilute to volume with 30% ethanol, develop color in a water bath at 35°C, and measure OD510nm at 510nm after 10 minutes to obtain the regression equation: Y(100ug / ml)=0.5605+91.9819 OD510nm[r=0.99 ** ], and then convert to calculate the content of flavonoids.

Embodiment 2
[0029] The dry powder of 1 kg of wrinkled papaya was placed in the extraction kettle, and CO was continuously fed at a speed of 2 kg / hour. 2 Carry out extraction and elution, collect the CO that the extraction time is 0.5 hours flowing out of the extraction kettle 2 , the pressure is relieved to normal pressure, and the residue after pressure relief is obtained, which is the active ingredient of wrinkled papaya.
[0030] CO in the extraction kettle 2 The temperature is 32℃, and the pressure is 8~15Mpa.
[0031] Adopt the method of embodiment 1 to detect, wherein:
[0032] Total flavonoids: 460.25mg / 100g FW, Vc: 209.35mg / 100g FW, total saponins: 896.44mg / 100g FW, oleanolic acid: 62.15mg / 100g FW.
[0033] Example 2
[0034] The dry powder of 1 kg of wrinkled papaya pulverized was placed in the extraction kettle, and CO was continuously fed at a speed of 25 kg / hour. 2 Carry out extraction and elution, add 10 kilograms of 35% aqueous ethanol solutions ...
