Galangin (Norizalpinin) is an agonist/antagonist of the arylhydrocarbon receptor. Galangin (Norizalpinin) also shows inhibition of CYP1A1 activity.

Kaempferide is an orally active flavonol isolated from Hippophae rhamnoides L. Kaempferide has anticancer, anti-inflammatory, antioxidant, antidiabetic, antiobesity, antihypertensive, and neuroprotective activities. Kaempferide induces apoptosis. Kaempferide promotes osteogenesis through antioxidants and can be used in osteoporosis research.

Helichrysetin is isolated from the flower Helichrysum odoratissimum. Helichrysetin is an ID2 (DNA binding inhibitor 2) inhibitor. Helichrysetin induces apoptosis. Helichrysetin has anti-tumor and antioxidant activity.

Tolazoline hydrochloride (Imidaline hydrochloride) is an α-adrenergic receptor antagonist. Tolazoline hydrochloride inhibits Noradrenaline (HY-13715)-induced cell contraction, modulates vascular resistance, increases arterial pressure, and reverses bradycardia and tachypnea. Tolazoline hydrochloride can be used to study erectile dysfunction, α₂-adrenergic receptor agonist-related poisoning, and skin vascular disease research.

(E)-p-Coumaryl alcohol is a metabolite of coumarin that has significant cytotoxicity. (E)-p-Coumaryl alcohol can be isolated from Alpinia officinarum and Rhodiola rosea and can be used for inflammation research.

p-Coumaryl alcohol is an antioxidant that can be isolated from Alpinia officinarum Hance. p-Coumaryl alcohol has inhibitory effect during the autoxidation of methyl linoleate.

Galangin (Standard) is the analytical standard of Galangin. This product is intended for research and analytical applications. Galangin (Norizalpinin) is an agonist/antagonist of the arylhydrocarbon receptor. Galangin (Norizalpinin) also shows inhibition of CYP1A1 activity.

Kaempferide (Standard) is the analytical standard of Kaempferide. This product is intended for research and analytical applications.

Bisdemethoxycurcumin is an orally effective curcuminoid. Bisdemethoxycurcumin downregulates pro-inflammatory cytokines in macrophages by inhibiting the phosphorylation of PI3K/Akt and p38 MAPK. Bisdemethoxycurcumin relieves autophagy inhibition and promotes lipophagy to clear vascular smooth muscle foam cells by inhibiting the PDK1/Akt/mTOR pathway. Bisdemethoxycurcumin activates the cAMP/Epac/AMPKα axis and the NRF2/HO-1 antioxidant axis, thereby indirectly inhibiting the phosphorylation of NF-κB p65 and pro-inflammatory outputs such as IL-1β/IL-6/TNF-α, so as to alleviate pulmonary oxidative stress, inflammatory infiltration and pulmonary edema. Bisdemethoxycurcumin blocks NLRP3-mediated pyroptosis and protects cartilage extracellular matrix degradation by activating NRF2/HO-1. Bisdemethoxycurcumin also exerts a synergistic effect with potassium iodide against Candida.

(E)-Ethyl p-methoxycinnamate is a natural product found in Kaempferia galangal with anti-inflammatory, anti-neoplastic and anti-microbial effects. (E)-Ethyl p-methoxycinnamate inhibits COX-1 and COX-2 in vitro with IC₅₀s of 1.12 and 0.83 μM, respectively.

3-O-Methylgalangin (Galangin 3-methyl ether) is a natural flavonoid compound from the rhizome of Alpinia officinarum (AO) with antibacterial activities, which also inhibits pancreatic lipase.

Officinaruminane B (compound 2), a diarylheptanoid, is a nature product that could be isolated from the rhizome of Alpinia officinarum.

4-Hydroxyphenylacetylglutamic acid is a metabolite of Morus alba L.

(4E)-7-(4-Hydroxyphenyl)-1-phenylhept-4-en-3-one (Compound 8) is a diarylheptanoid containing two benzene rings. Diarylheptanoid is widely distributed in Alpinia, and exhibits cytotoxic, anti-inflammatory, antiplatelet, antioxidant, and antiproliferative activities.

(R)-5-Hydroxy-1,7-diphenyl-3-heptanone is a diarylheptanoid that can be found in Alpinia officinarum. (R)-5-Hydroxy-1,7-diphenyl-3-heptanone ameliorates oxidative stress and insulin resistance via activation of Nrf2/ARE pathway.

4',​7-​Di-​O-​methylnaringenin ((−)-NRG-DM) is a flavonoid found in Renealmia alpinia. (−)-NRG-DM inhibits Nav1.7, Nav1.8 and Kv2.1 channels and has analgesic activity. Intraperitoneal administration of (−)-NRG-DM dose-dependently attenuated pain in a formalin-induced mouse inflammatory pain model and mustard oil-induced mouse colorectal pain model[²].

Alpinia officinarum polysaccharide is a polysaccharide derived from Alpinia officinarum.

Alpinin A is a diarylheptanoid found in the rhizomes of Alpinia officinarum. Alpinin A can strongly inhibit the aggregation of α-synuclein with inhibition rate of 66% at 10 μM. Alpinin A can be used for the research of neurological disease, such as Parkinson’s disease.

(3S,5S)-Octahydrocurcumin ((3S,5S)-Hexahydrobisdemethoxycurcumin) is a fungal metabolite that can be isolated from Curcuma longa.

Antiviral agent 65 (compound 9) is an antiviral agent that targets influenza H1N1 virus (EC₅₀=7 μg/mL).
