Embodiment 1
[0027] The preparation of embodiment 1 purple red water swertia active components (method one)
[0028]Take 25kg of the whole herb of Swertia chinensis, crush it, put it in a stainless steel extraction tank, add 85% alcohol and heat it for 3 times, the amount of alcohol used each time is that the liquid level is submerged and is about 5-10cm higher than the medicinal material, and the first reflux 2 hour, the 2nd and 3rd times were refluxed for 1 hour respectively; the combined alcohol extract was concentrated under reduced pressure to obtain 4.6kg of extract, and the specific gravity was 1.25; 40kg of water was added to the extract, fully stirred, and a large amount of tan precipitate was seen to separate out; filter, Wash the precipitate with water, drain it, dry it in vacuum, grind it finely, use 6 times the amount of petroleum ether to reflux three times to degrease, filter the insoluble part, drain it, and evaporate the solvent to get 0.76kg of yellow-brown powder, which i...
Embodiment 2
[0030] The preparation of embodiment 2 purple red Swertia active components (method two)
[0031] Take 25kg of the whole herb of Swertia chinensis, crush it, put it in a stainless steel extraction tank, add 0.2% NaOH, heat and reflux for extraction 3 times, combine the alkaline water extract, add 10% H 2 SO 4 When the pH value is 2-3, the precipitate is collected by filtration, washed with water, and dried to obtain 0.82 kg of yellow-brown powder, which is the effective component of purple-red Swertia japonicus, with a yield of 3.28%.
Embodiment 3
[0032] Embodiment 3 Assay
[0033] 1. Determination of total ketone content
[0034] Accurately take by weighing 30 mg of the effective components of the purple red Swertia japonica obtained in Example 1, put in a 10ml measuring bottle, add methanol to dissolve and dilute to the mark, shake up; accurately draw 1ml of the solution, put it in a 100ml measuring bottle, add methanol to dilute to the mark, Shake up; according to spectrophotometry, measure the absorbance at the wavelength of 333nm, according to the absorption coefficient (E 1cm 1% ) for 330 calculations. The content of total ketone in this sample is calculated according to gentio-ketone phenol (C 14 h 10 o 6 ) meter, the measured result is 40.6%.
[0035] 2. Determination of oleanolic acid content
[0036] Accurately weigh 50 mg of the obtained purple swertia oleifera active ingredient and 10 mg of the oleanolic acid reference substance in Example 1, put them in 25 ml measuring bottles respectively, add metha...
