A resveratrol-containing composition capable of providing a therapeutic benefit to a subject such as modulation of a biological activity, improving cell transplantation therapy, or improving macular degeneration or dystrophy treatments. The compositions comprise trans-resveratrol, a metal chelator, and one or more additional antioxidants such as phenolic antioxidants or vitamin D.

The invention provides a preparation method of resveratrol, which relates to the field of medicament preparation and solves the problems of low preparation conversion rate, low yield and poor product quality of resveratrol in the prior art. The process comprises the following steps: pretreating giant knotweed used as raw material, washing away dust of the giant knotweed, cutting the giant knotweed into slices or preparing the giant knotweed into coarse powder, adding ethanol and heating to carry out reflux extraction, decompressing and distilling extract liquid to recover the ethanol, concentrating the ethanol into stiff paste, diluting the stiff paste by water for 10 times, adding enzymolysis liquid to carry out enzymolysis, heating and filtering the enzymatic enzymolysis liquid, decoloring the enzymolysis liquid by activated carbon, repeatedly recrystallizing the enzymolysis liquid by alcohol, and finally decompressing and drying the enzymolysis liquid to obtain a white resveratrol solid with purity of more than 98 percent. The extraction method of resveratrol greatly improves the production efficiency and the conversion rate, promotes active substances in the raw material to be converted into trans-resveratrol more, and further improves the quality of products with high purity, thereby being suitable for industrial production.

A dietary supplement system includes a dietary supplement composition for oral administration by an individual in the morning, the composition, including (a) a telomere maintenance complex including: Purslane extract (aerial parts); Turmeric rhizome extract (95% curcuminoids); Quercetin dehydrate, Cayenne pepper fruit; Vanadium (as vanadyl sulfate); Fenugreek seed; Astragalus root extract, Omega fatty acid complex including linoleic acid; alpha-linolenic acid; oleic acid borage seed oil gamma-linolenic acid), evening primrose oil fish body oil (eicosapentaenoic acid; docosahexaenoic acid); (b) a calorie restriction mimetics and gene expression complex including Trans-resveratrol (from Polygonum cuspidatum root extract); Pterostilbene Fisetin 50% (Buxus microphlla Sieb (stem and leaf; Alpha lipoic acid, Coenzyme Q-10, Betaine HCl, Sulfur (from methylsulfonylmethane); L-Carnitine tartrate; L-Carnitine HCl, and (c) a free radical scavenger complex, including Green tea leaf extract catechin and polyphenols); Anthocyanins (from bilberry fruit and grape skin extracts).

The invention discloses a brewing method of distilled wine in the food domain, which adds trans-chenopodium veratryl alcohol in the allocated wine.

The invention relates to a method for synthesizing trans-resveratrol as a functional food additive, which is characterized in that 3,5-methoxybenzylchloride is obtained after 3,5-methoxybenzylalcohol is chloro-substituted in DMF-triethylamine mixed solvent; 3,5-methoxy benzyl diethyl phosphate is obtained after the 3,5-methoxybenzylchloride reacts with triethyl phosphite; 3,4',5-trimethoxy toluylene is obtained after reaction products and anisic aldehyde are subjected to Witting reaction; and the trans-resveratrol is generated by removing methoxyl under the catalysis of N-methylaniline and aluminium trichloride. The method has the advantages of economical and readily available raw materials, mild reaction conditions, easy product purification, high reaction yield, friendliness to environment, simple operation and the like, thereby adapting to industrial production.

Processes for the separation and purification of polyphenol trans-resveratrol and / or anthraquinone emodin from Polygonum cuspidatum and / or Rumex acetosa, by means of solvent selective extraction. Products obtained by this process present high level of purity; being therefore useful in the preparation of nutraceutical (pharmaceutical and / or food) compositions with antioxidant, anti-inflammatory, antiviral, cardioprotective, neuroprotective, chemoprotective activities, besides protecting against infections and ischemia, treating type 1 and 2 diabetes, reducing obesity and preventing aging. Useful phytomedicines for the same therapeutic activity and prepared from the roots and / or rhizomes of Rumex acetosa or from their fractions are also provided.

The present invention relates to a topical composition to enhance sexual response. The composition includes L-arginine, trans-resveratrol, and a topical carrier wherein L-arginine is present in an amount not greater than about 10% and trans-resveratrol is present in an amount not greater than about 10% based upon the weight of the total composition. The invention also relates to a method of enhancing sexual response by topically applying the topical composition to the genetalia of a human, and an integrated product including the topical composition, a container for instantaneous delivery, and instructions for use.
