1. Desoxyrhaponticin (Deoxyrhaponticin) is an agent that is potentially effective in controlling postprandial hyperglycemia in diabetes, the in vivo antidiabetic action of this compound can be explained, in part at least, by inhibition of glucose transport in the small intestine and inhibition of glucose reabsorption in the kidney. 2. Desoxyrhaponticin and rhaponticin could be considered as promising fatty acid synthase(FAS) inhibitors, they could inhibit intracellular FAS activity and downregulate FAS expression in human breast cancer MCF-7 cells.

D-Arabitol is a polyol that can lead to neurotoxicity when accumulated in the body.

Rhapontigenin (Protigenin) is a mechanism-based, selective inactivator of cytochrome P450 1A1 (IC50: 400 nM), an aryl hydrocarbon hydroxylase which activates polycyclic aromatic hydrocarbons that act as procarcinogens. Rhapontigenin is a natural analog of resveratrol with antioxidant and anti-cancer activity. At higher concentrations, rhapontigenin inhibits the proliferation of HL-60R and HepG2 cancer cell lines (IC50: 48 μM).

Aloe-emodin-8-O-β-D-glucopyranoside (Aloe-emodin-8-O-beta-D-glucopyranoside) exhibits moderate bioactivity against human Protein Tyrosine Phosphatase 1B (hPTP1B) in vitro.

Emodin-8-glucoside (Anthraglycoside B) functions to protect from focal cerebral injury induced by ischemia and reperfusion. Emodin-8-beta-D-glucoside directly stimulates cell proliferation and differentiation of osteoblasts.

Diacerein (Fisiodar) is a prodrug which is metabolized to rhein. It is currently approved in France for the treatment of osteoarthritis although the use of diacerein is restricted due to the side effects including sevre diarrhea [L780]. Diacerein is under investigation for the treatment of Insulin Resistance, Diabetes Mellitus (Type 2), and Diabetes-Related Complications.

4-Hydroxybenzoic acid (4-hydroxybenzoate) is a monohydroxybenzoic acid, a phenolic derivative of benzoic acid. It is a white crystalline solid that is slightly soluble in water and chloroform but more soluble in polar organic solvents such as alcohols. It could inhibit most gram-positive and some gram-negative bacteria, with an IC50 of 160 μg/mL.

Physcion 8-O-β-D-glucopyranoside (Physcion 8-O-beta-D-monoglucoside) has anti-inflammatory and anti-cancer activities. Physcion 8-O-β-D-glucopyranoside can be used in studies about common malignancy cancer.

Chrysophanol (Turkey Rhubarb) is an EGFR/mTOR pathway inhibitor, which can be found in rhubarb, and sorrel.

Piceatannol 3'-O-glucoside (Piceatannol 3-glycoside) increases pulmonary blood oxygen tension and decreases pulmonary interstitial edema, so it can protect lung injury.
