Curculigo orchioides Gaertn.

Orcinol gentiobioside (compound 4) is a natural product isolated from the rhizomes of C. breviscapa.

Curculigoside is the main saponin in C. orchioide, exerts significant antioxidant, anti-osteoporosis, antidepressant and neuroprotection effects. Curculigoside possesses significant anti-arthritic effects in vivo and in vitro via regulation of the JAK/STAT/NF-κB signaling pathway.

Orcinol glucoside is an orally active, blood-brain barrier permeable osteoblast proliferation promoter that targets the Nrf2/Keap1, mTOR and p38 signaling pathways. Orcinol glucoside promotes Nrf2 nuclear translocation, upregulates antioxidant enzyme levels, enhances the phosphorylation of mTOR and p70S6K, and inhibits the enzymatic activity of HAS2 as well as the nuclear translocation of GR. Orcinol glucoside also alleviates oxidative stress, inhibits autophagic flux, osteoclastogenesis and TGF-β1-induced M2 polarization, while reducing collagen deposition and effectively promoting the proliferation, differentiation and mineralization of osteoblasts. Orcinol glucoside also exhibits anti-pulmonary fibrosis, anxiolytic and antidepressant activities. Orcinol glucoside can be used in the research of senile and glucocorticoid-induced osteoporosis, idiopathic pulmonary fibrosis (IPF), anxiety and other related diseases.

Curculigoside B, a phenolic glycoside isolated from Curculigo orchioides, enhances the osteoblast proliferation, decreases the area of bone resorption pit, osteoclastic formation and TRAP activity. Antiosteoporotic and antioxidative activities.

Curculigoside (Standard) is the analytical standard of Curculigoside. This product is intended for research and analytical applications. Curculigoside is the main saponin in C. orchioide, exerts significant antioxidant, anti-osteoporosis, antidepressant and neuroprotection effects. Curculigoside possesses significant anti-arthritic effects in vivo and in vitro via regulation of the JAK/STAT/NF-κB signaling pathway.

Orcinol glucoside (Standard) is the analytical standard of Orcinol glucoside. This product is intended for research and analytical applications. Orcinol glucoside (OG) is an active constituent isolated from Curculigo orchioides, with antidepressant effects. Orcinol glucoside facilitates the shift of MSC fate to osteoblast and prevents adipogenesis via Wnt/β-catenin signaling pathway.

Nyasicol ((+)-Nyasicol) is an enzymatic (β-glucosidase) hydrolysis product of Compound 3.

Nyasicoside is a norlignan glucosides that can be isolated from Curculigo capitulate. Nyasicoside has potent activity against ouabain-induced arrhythmia in the heart preparations of guinea pig.

Curculigoside C is a phenolic glucoside with potent antioxidative and neuroprotective activities. Curculigoside C shows IC₅₀ values of 0.25 mM and 0.88 mM for hydroxyl radicals and superoxide anion radicals, respectively.
