Hawthorn Extract
Based on 1 Customer Validation
Hawthorn Extract is an orally active hawthorn extract. Hawthorn Extract decreases Bax expression and increases Bcl-2 expression in the aorta. Hawthorn Extract regulates the AMPK signaling pathway, induces apoptosis, enhances the hepatic antioxidant system, and ameliorates symptoms of liver injury, inflammation and cancer. Hawthorn Extract reduces plasma levels of pro-inflammatory factors, increases plasma levels of anti-inflammatory adiponectin, and alleviates atherosclerotic plaque lesions in the aorta. Hawthorn Extract improves symptoms associated with chronic heart failure. Hawthorn Extract inhibits FMLP-induced superoxide anion production, Elastase release, ILB4 generation and calcium signaling in neutrophils, and also reduces LPS-induced cytokine production in neutrophils. Hawthorn Extract induces autophagy and inhibits the proliferation of intestinal stem cells. Hawthorn Extract can be used in research related to atherosclerosis, hepatitis, alcoholic liver disease, non-alcoholic fatty liver disease, hepatocellular carcinoma, chronic heart failure and hypotension.

Hawthorn extract (0.4-1%) protects human hepatocellular carcinoma HepG2 cells against alcohol-induced injury[2].
Hawthorn extract (0.5-8.66 μg/mL) reduces the viability of human hepatocellular carcinoma HepG2 cells; among them, the ethanol extract of C. pinnatifida fruit (0.8 mg/mL) induces cell apoptosis by altering the mRNA/protein levels of caspase-3, Bax and Bcl-2, the IC50 of the 80% acetone extract of C. pinnatifida fruit is 11.58 μg/mL, and the IC50 of the 80% ethanol extract of stems, flowers and fruits of C. armena is 8.66 μg/mL[2].
Hawthorn extract blocks repolarizing potassium currents in isolated guinea pig ventricular myocytes, mimicking the activity of class III antiarrhythmic drugs[3].
Hawthorn extract (0.75-250 μg/mL; 5 min preincubation, 60 min incubation with FMLP) potently inhibits FMLP-induced superoxide anion production in human peripheral blood neutrophils, with an IC50 of 43.6 μg/mL[5].
Hawthorn extract (0.75-250 μg/mL; 5 min preincubation, followed by incubation with FMLP) potently inhibits FMLP (HY-P0224)-induced elastase release from human peripheral blood neutrophils, with an IC50 of 21.9 μg/mL, and exerts no direct inhibitory effect on elastase activity[5].
Hawthorn extract (0.75-250 μg/mL; 30 min preincubation) potently inhibits FMLP-induced chemotactic migration of human peripheral blood neutrophils, with an IC50 of 31.6 μg/mL[5].
Hawthorn extract (125 μg/mL; 60 min preincubation, 5 min cytochalasin B treatment, 5 min FMLP incubation) significantly inhibits FMLP-induced production of LTB4 in human peripheral blood neutrophils, without affecting basal LTB4 release[5].
Hawthorn extract (125 μg/mL; 1 h preincubation, 8 h incubation with LPS) significantly inhibits LPS (HY-D1056)-induced production of TNF-α and IL-8 in human peripheral blood neutrophils, without affecting the baseline levels of cytokines[5].
Hawthorn extract (0.75-125 μg/mL; 10 min preincubation, FMLP stimulation) potently inhibits FMLP-induced elevation of [Ca2+]i in human peripheral blood neutrophils, with an IC50 of 17.4 μg/mL; at concentrations of 20 μg/mL and 125 μg/mL, it also blocks extracellular calcium influx, intracellular calcium release, and capacitative calcium influx[5].

Hawthorn extract (1-3 mg/mL; oral administration; continuous dietary supplementation) extends the lifespan of *Drosophila melanogaster* by up to 13.7% (average lifespan of male flies in the 3 mg/mL group), while improving their stress tolerance, enhancing antioxidant activity, maintaining intestinal homeostasis, inhibiting PI3K-Akt pathway activity, and activating autophagy[6].
