GAPDH served as a loading manage.liver diseases in China, Japan, Korea, and also other districts around the planet [35]. Separation and identification of active compounds from herbal medicine may possibly offer potential drugs for HCC and enable enhance the prognosis of this deadly disease.Huang-qin, the root of Scutellaria baicalensis Georgi, has been a significant element of numerous standard treatments for liver issues, such as HCC [17, 21, 368]. Contemporary sciences recommend that flavonoids in Huang-qin could be accountable for therapeutic effects of this herbal medicine [39].
