Sichuan Pepper Extract

Synonyme: Zanthoxylum bungeanum extract, Szechuan pepper extract, Hua Jiao extract, Sichuan pepper oleoresin, sanshool extract.

Sichuan Pepper Extract is a standardized concentrate derived from the dried pericarps of Zanthoxylum bungeanum Maxim. The key bioactive compounds are sanshools, a family of unsaturated alkylamides that include hydroxy-alpha-sanshool, hydroxy-beta-sanshool, and hydroxy-gamma-sanshool. These molecules are responsible for the characteristic tingling and numbing sensation (málà) and have drawn interest for their pharmacological properties.

Our extract is produced via hydroalcoholic extraction followed by concentration and spray drying, yielding a fine powder standardized to ≥95% total sanshools by HPLC. It is designed for use in dietary supplements, functional foods, and research applications where a consistent, high-purity botanical ingredient is required.

Chemical Structure & Properties

Sanshools are alkylamides with a polyunsaturated fatty acid chain linked to an isobutylamine moiety. The presence of multiple cis and trans double bonds contributes to their lipophilic nature and instability under light and heat. The extract is typically off-white to light yellow, with a characteristic pungent taste and aroma. It is soluble in ethanol and other organic solvents, but only slightly soluble in water.

Mechanism of Action

• TRPV1 and TRPA1 activation: Sanshools activate transient receptor potential channels, producing the tingling sensation and modulating pain perception.
• Anti-inflammatory effects: They inhibit the NF-κB pathway, reducing pro-inflammatory cytokine production.
• Antioxidant activity: The conjugated double bonds scavenge free radicals and enhance endogenous antioxidant enzymes.
• Antimicrobial properties: Demonstrated activity against certain bacteria and fungi, supporting food preservation applications.
