Embodiment 1
[0010] Example 1 Preparation of Total Flavonoids Extract from Diangui Ainaxiang
[0011] Take 30kg of Diangui Ainaxiang, chop, soak in water for 3 hours, extract twice, add water 10 and 8 times respectively, and extract for 1.5 hours and 1 hour respectively, filter, concentrate the filtrate, and the relative density of the concentrate is 1.10 (measured at 60°C), put on HPD100 macroporous adsorption resin column, the loading amount is medicinal material weight: macroporous resin weight=1.5:1, eluted with water, then eluted with 30% ethanol, and finally eluted with 60% ethanol , collect 60% ethanol eluate, concentrate after recovering ethanol, and dry to obtain 0.65 kg of total flavonoids extract of Ainaxiang osmanthus Dianensis; with rutin as reference substance, spectrophotometric determination shows that the total flavonoids content in the extract is 60% (Assay method refers to Chinese Pharmacopoeia 2005 edition one P246: Determination of total flavonoid content of Sophora ja...
Embodiment 2
[0012] Example 2 The preparation of the total flavonoids extract of Ai Naxiang from Yunnan
[0013] Take 30kg of Diangui Ainaxiang, chop, soak in water for 3 hours, extract twice, add water 10 and 8 times respectively, and extract for 1.5 hours and 1 hour respectively, filter, concentrate the filtrate, and the relative density of the concentrate is 1.13 (measured at 60°C), put on an AB8 macroporous adsorption resin column, the loading amount is the weight of medicinal material: weight of macroporous resin = 1:1, eluted with water, then eluted with 40% ethanol, and finally eluted with 70% ethanol , collect 70% ethanol eluent, concentrate after reclaiming ethanol, dry, and obtain 0.80kg of total flavonoids extract of Ai Naxiang Diangui; with rutin as reference substance, spectrophotometric determination, the total flavonoids content in the extract is 57% (Assay method refers to Chinese Pharmacopoeia 2005 edition one P246: Determination of total flavonoid content of Sophora japon...
Embodiment 3
[0014] Example 3 Efficacy Test of Total Flavonoids Extract from Diangui Ainaxiang
[0015] [sample]
[0016] The test product is an aqueous solution containing 100 mg of total flavonoids extract of Aiinaxiang yunnanensis per ml, which is equivalent to 4 g of the original medicinal material per ml. When used, it is diluted or concentrated, so that the administration volume of animals in each dosage group is equal. The doses in this test are expressed in g / kg of the original medicinal material.
[0017] [Experimental animals]
