The invention relates to a general flavone extractive of an immature bitter orange or a bitter orange. The general flavone extractive is extracted through the following steps:
cutting the immature bitter orange or the bitter orange into decoction pieces or smashing the immature bitter orange or the bitter orange, adding 4 to 15 times of water, decocting 1 to 3 times (1 to 3 hours each time), merging the decoction liquids, filtering through processed non-polar big hole resin, eluting by water and
alcohol of which the concentration is lower than 20 percent sequentially to remove impurities, eluting by
alcohol of which the concentration ranges from 25 to 90 percent and
sodium hydrate of which the concentration ranges from 0.5 to 2 percent, collecting
alcohol eluant, depressuring and concentrating to obtain a
liquid extract of which the
relative density is 1.20 to 1.40 (under the temperature
ranging from 50 DEG C to 70 DEG C), depressuring and
drying under the temperature
ranging from 60 DEG C to 80 DEG C, and smashing to obtain the general flavone extractive of the immature bitter orange or the bitter orange. The extractive can be used for preparing medicines used for curing gastrointestinal
dyskinesia-type functional
indigestion, epigastralgia, abdominal distention, asitia,
eructation,
nausea, and vomit caused by chemotherapeutics and other reasons, and is prepared into dosage forms acceptable for
pharmacology.
