Embodiment 1
[0020] Example 1: Preparation of vernophilic acid fraction for repelling insects:
[0021] Grind 10kg of dried Vernonia fruit medicinal materials, add 30 times the volume of aqueous solution, heat and reflux for extraction 3 times at 95°C for 3 hours, cool to room temperature, filter, combine the extracts, and concentrate under reduced pressure until there is no alcohol smell , to obtain alcohol extract;
[0022] Disperse the obtained alcohol extract with 5% ethanol to contain crude drug 100g / L, filter, and then use AB-8 macroporous adsorption resin column to elute with 1 times the column volume of water, and then use 8 times the column volume The concentration is 40% ethanol for elution, the ethanol eluate is collected, concentrated under reduced pressure, and dried in vacuum to form a dry powder, which contains 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid and 3, Insect Repelling Vernophilic Acid Fraction of 4-dicaffeoylquinic Acid 390g.
Embodiment 2
[0023] Example 2: Preparation of vernophilic acid fraction for repelling insects:
[0024] Grind 10kg of the dried Vernonia fruit medicinal material, add 3 times the volume concentration of 95% ethanol, heat and reflux for extraction 5 times at room temperature for 3 hours, cool to room temperature, filter, combine the extracts, concentrate under reduced pressure until alcohol-free Taste, to obtain alcohol extract;
[0025] The ethanol extract that obtains is that 5% ethanol is dispersed to contain crude drug 50g / L with concentration, centrifugation (4000 revs / min), DM-130 type macroporous adsorption resin column, first with 3 times column volume water eluting, then use 1 times the column volume concentration is 95% ethanol for elution, collect the ethanol eluate, concentrate under reduced pressure, and dry it in vacuum to dry powder, which contains 3,5-dicaffeoylquinic acid and 4,5-dicaffeoylquinic acid Anthelmintic Vernophilic Acid Fraction of Acid and 3,4-dicaffeoylquinic ...
Embodiment 3
[0026] Example 3: Preparation of Vernophilic Acid Fraction for Repelling Insects:
[0027] Grind 10 kg of dried Vernonia fruit medicinal materials, add 15 times the volume concentration of 30% ethanol, heat and reflux for extraction 3 times at 75°C for 2 hours, cool to room temperature, combine extracts, and concentrate under reduced pressure until alcohol-free Taste, to obtain alcohol extract;
[0028] The extract that is obtained is that 10% methanol is dispersed to contain crude drug 80g / L with concentration, centrifugation (4000 revs / min), HPD-100 type macroporous adsorption resin column, first with 4 times column volume water elution, then with 6 The column volume concentration is 50% ethanol for elution, the ethanol eluate is collected, concentrated under reduced pressure, and dried in vacuum to dry powder, which contains 3,5-dicaffeoylquinic acid and 4,5-dicaffeoylquinic acid and 3,4-dicaffeoylquinic acid's repellent vernophilic acid fraction 440g.
