Kavalactone 70% CAS 9000-38-8
Kavalactone：Natural Relaxant
Kavalactone is a group of fat-soluble active compounds derived from the roots and rhizomes of *Piper methysticum*, belonging to the α-pyranone derivative class. Kavalactone is primarily composed of six core alkaloids, including capsaicin and dihydrocapsaicin, typically comprising 30% to 70% of the standard extract. Pharmacologically, it exhibits a variety of biological activities, including sedation, sleep aid, antibacterial activity, and analgesia. The preparation of these compounds often employs a multi-stage ethanol extraction process, followed by quality analysis using high-performance liquid chromatography (HPLC). It is currently widely used in the manufacture of dietary supplements and traditional herbal products.
Kavalactone contains six core active ingredients:
Kavain; Dihydrokavain; Methysticin; Dihydromethysticin; Yangonin; Desmethoxyyangonin;
Kavain constitutes the largest proportion, reaching 15%-20% of the total content. The extract also contains various organic acids, amino acids, and inorganic trace elements.
Physiological Functions of Kavalactone
Sedative and Anxiety-Relieving Effects
This ingredient enhances the activity of gamma-aminobutyric acid (GABA) receptors in the brain, thereby inhibiting central nervous system excitation and producing a significant sedative effect. Its effect in relieving mild to moderate anxiety is comparable to low-dose anti-anxiety medications, and it is less likely to cause dependence. It is also commonly used to assist in improving sleep disorders associated with anxiety.
Relief of Muscle Tension
Kavalactone can regulate nerve signals to muscle contraction, reducing muscle stiffness and soreness caused by stress, fatigue, or exercise, thus promoting overall relaxation.
Analgesia and Local Anesthesia
Ingredients such as kavalactone exhibit analgesic properties, with effects superior to conventional antipyretic analgesics in some models. It also possesses local anesthetic effects, with a mechanism similar to some topical anesthetics.
Antibacterial Properties
In vitro studies have shown that kavalactone has a certain inhibitory capacity against pathogenic bacteria such as Neisseria gonorrhoeae and Enterobacteriaceae. It is commonly used in traditional medicine as an adjunct treatment for infectious symptoms.
Skincare Benefits
This ingredient reduces stinging, redness, and itching in sensitive skin by interfering with signal transmission at sensory nerve endings.
Multiple Applications of Kavalactone
As a natural active ingredient, kavalactone has applications spanning multiple fields including health, skincare, and culture, specifically including the following:
Pharmaceutical and Healthcare Fields
In medical and health management, kavalactone is commonly used for mood regulation and physiological soothing. It alleviates mild to moderate anxiety and tension by enhancing the function of the GABA neurotransmitter, with effects approaching those of conventional anti-anxiety medications and with low dependence. This ingredient is also used to improve anxiety-related sleep problems, helping users enter a relaxed state. In addition, kavalactone has certain muscle relaxant and local analgesic effects, and can be used to relieve muscle discomfort caused by stress or fatigue. Some derivatives are more effective than common antipyretic analgesics in analgesia. Its antibacterial and anti-inflammatory properties are also used as an adjunct treatment for specific bacterial infections and inflammatory responses.
Skincare and Cosmetics Fields
In skincare products, kavalactone is widely used in sensitive skin care products. By inhibiting sensory nerve signal transmission, it effectively reduces skin redness, stinging, and itching, while helping to repair the skin barrier. Its anti-inflammatory properties help relieve acne and pimples, and soothe irritated skin. This ingredient also possesses antioxidant capabilities, neutralizing free radicals and promoting collagen synthesis, thereby delaying skin aging and improving firmness and elasticity. Furthermore, some skin-whitening products utilize its melanin-inhibiting effects to improve uneven skin tone and pigmentation issues.
Food and Supplements
Kavalactone is often processed as a herbal extract into capsules, tablets, and other forms of dietary supplements for mood support, stress relief, and sleep promotion, suitable for those needing to regulate their mental state or improve sleep quality.
Other Applications
Recent studies have shown that this ingredient has potential in maintaining mitochondrial function and anti-aging interventions, possibly acting through antioxidant and barrier repair mechanisms. In the South Pacific region, kavagan is traditionally used as a ritual drink in social gatherings and religious ceremonies, symbolizing peace and connection, reflecting its profound cultural value.
