α-D-Glucose-1,6-bisphosphate is abis-phosphorylated derivative of α-D-glucose that has roles in carbohydrate metabolism.1It is the product of the reaction of glucose-1- or 6-phosphate with glucose-1,6-bisphosphate synthase (PGM2LI) in the conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate.2It is also a cofactor for the bacterial enzyme phosphopentomutase.3,4α-D-Glucose-1,6-bisphosphate has been used in the study of carbohydrate metabolism.

7,4'-Dihydroxy-8-methylflavan can significantly promote mesenchymal stem cells (MSCs) osteogenic differentiation by increasing the levels of alkaline phosphatase (ALP) activity. 7,4'-Dihydroxy-8-methylflavan also has free radical scavenging properties.
Alloisoimperatorin is a candidate of AChE inhibitors, it displays potent antioxidant effects against the DPPH radical and against renal epithelial cell injury by using AAPH to generate peroxyl radicals in vitro. Alloisoimperatorin has estrogenic activity
Serratenediol demonstrates strong inhibitory effects on the Epstein-Barr virus early antigen (EBV-EA) activation without showing any cytotoxicity, its effects being stronger than that of a representative control, oleanolic acid. Serratenediol can promote
