The quality specification of ginkgo biloba extract in CP2005:
Preparation: Withdraw under a reflux condenser of ethanol ,adsorb with macroporous resin, spray to dry, comminute.
Character: Yellowish brown to brownish powder, mildly bitter fl***our
Test: Moisture<5.0%
Residue on ignition<0.8%
He***y metal is not more than twenty millionths, namely less than 20ppm
The peak area ratio of fl***onoid glycoside, namely Quercatin: kaemperol should be 0.8--1.5
Total ginkgo acid should be not more than ten millionths, namely 10ppm
Assay: High performance liquid chromatography
Total Ginkgo fl***one glycosides >24%
The content of total ginkgo fl***one glycosides is the sum of the content of quercatin, kaemperol and isorhamnetin (Quercatin: kaemperol 0.8-1.5. If it surpasses 1.5, it should be suspected to add quercatin.)
Total terpene lactones > 6%
The content of total terpene lactones is the sum of the content of bilobalide, ginkgolide A, B and C.
Function:
Promoting blood circulation, removing blood stasis and obstruction in the channels. It is indicated in the prevention and treatment of obstruction of Qi in chest and stroke induced by blood stasis with symptoms including chest pain, palpitati***, stiff tongue, dysphasia or aphasia, hemiparalysis, coronary disease, angina pectoris, Cardiac infarction, cerebral coronary thrombembolia,etc.
it is widely used as the additive in health care products, foods, beverages and co***etics etc.
