Apples contain many kinds of polyphenols, and the main components are oligomeric procyanidins. Applephenon is apple polyphenol extract produced commercially from unripe apples, and has been used as food additive in order to prevent oxidation of components in foods and its application in functional foods is expected. In a lipid metabolism regulation study, administration of Applephenon has the potential to exert strong anti-oxidative activity and to inhibit consumption of vitamin E and anti-oxidative enzymes. Double blind clinical trials of Applephenon on pediatric patients with atopic dermatitis, and tests using type I allergic model mice suggested that Applephenon might regulate allergic reactions. We found the no observed adverse effect level (NOAEL) of Applephenon is greater than 2000 mg/kg in a 90~day consecutive oral administration toxicity test in rats, and Applephenon is safe and acceptable based on mutagenicity tests.

Objective: We examined the effects of Applephenon and ascorbic acid administration on physical fatigue.
Methods: In a double-blinded, placebo-controlled, three-way crossover design, 18 healthy volunteers were randomized to oral Applephenon (1200 mg/d), ascorbic acid (1000 mg/d), or placebo for 8 d. The fatigue-inducing physical task consisted of workload trials on a bicycle ergometer at fixed workloads for 2 h on two occasions.

Plant polyphenols, RG-tannin, and applephenon had been reported to inhibit cholera toxin (CT) ADP-ribosyltransferase activity and CT-induced fluid accumulation in mouse ileal loops. A high molecular weight fraction of hop bract extract (HBT) also inhibited CT ADP-ribosyltransferase activity. We report here the effect of those polyphenols on the binding and entry of CT into Vero cells.

Apple polyphenol extract has strong antioxidant activity and various physiological functions, and is used in Japan as a food additive and nutritional supplements. Here, we tested the consumption safety of Applephenon, which is a polyphenol extract produced from unripe apples. The Ames test without S9 mixture revealed that Applephenon, had slight mutagenicity at a high concentration of 2500 microg/plate; however, both chromosomal aberration test and the micronucleus test found no significant mutagenicity.
