Embodiment 1
[0033] (1) get the dried whole grass of the goldenrod oleracea, add 40% ethanol and heat under reflux for extraction twice, 3 hours each time, combine the extracts, concentrate the extracts, and dry to obtain the extract;
[0034] (2) The extract was dissolved in water, passed through macroporous resin D101, washed with water until neutral, then eluted with 10% ethanol, until the eluent was colorless, and then eluted with 50% ethanol, and finally collected 50 % ethanol eluent is concentrated and dried to obtain the total saponins of 20% to 90% of luteolin.
Embodiment 2
[0036] (1) get the dried whole grass of the yellow flower oleracea, add 65% ethanol to heat and reflux for extraction 3 times, each time for 2 hours, combine the extracts, concentrate the extracts, and dry to obtain the extract;
[0037] (2) This extract was dissolved in water, passed through macroporous resin D201, washed with water until neutral, then eluted with 15% ethanol, until the eluent was colorless, and then eluted with 65% ethanol, and finally collected 65 % ethanol eluent is concentrated and dried to obtain the total saponins of 20% to 90% of luteolin.
Embodiment 3
[0039] (1) Take the dried whole grass of the yellow flower oleracea, add 90% ethanol and heat under reflux for extraction for 4 times, each time for 0.5 hours, combine the extracts, concentrate the extracts, and dry to obtain the extract,
[0040] (2) The extract was dissolved in water, passed through macroporous resin AB8, washed with water until neutral, then eluted with 20% ethanol, until the eluent was colorless, then eluted with 80% ethanol, and finally collected 80% ethanol. % ethanol eluent is concentrated and dried to obtain the total saponins of 20% to 90% of luteolin.
[0041] In the embodiment, the organic solvent can also be selected from methanol, ethyl acetate and acetone, the extraction method adopts ultrasonic extraction method, supercritical extraction method, immersion method and microwave method, and the macroporous resin is selected from SP825, DS401, DS100, HPD600, HPD100, DM301, DM130.
