The chemistry and biosynthesis of resveratrol.

In 1976, Drs. Langcake and Pryce reported the presence of resveratrol and its derivatives in grapevine tissues.
 It was discovered at that time that plants produced resveratrol when they were under attack by fungi, bacteria, or viruses.
 This led to the conclusion that resveratrol was a natural protectant to plants under times of stress, and also led to the beginning of studies to examine whether resveratrol could be beneficial to humans.
 Plant antibiotics such as resveratrol are known as phytoalexins.
 These compounds are the members of the plant kingdom classified as spermatophytes.
 The chemical structure of resveratrol is important because from its structure chemists can determine some properties related to its benefit.
 
 Figure 1 shows the molecular structure of cis and trans-resveratrol and some of their derivatives. The hexagons in the figure are called aromatic rings, and the OH groups are called hydroxyl groups.
 When aromatic rings and hydroxyl groups are together the chemical is called a phenol. Since there are more than one of these phenols present, the compounds are called polyphenols. Polyphenols are often associated with compounds that are antioxidants.
 This is because they can react with radicals to form a more stable molecule; one that is less toxic than the original radical.
 
 Figure 2 shows the way resveratrol and its derivatives are biosynthesized naturally in plants.
 More functions proved to have, such as killing bacteria;good for ladies in menopause;strenthening pallium controlling ability;and with good calming pound;hypnosising anti-convulsion;adjusting blood pressure;and more other functions
 Transresveratrol also widely used as aroma;health caring food ,nutrition supplying and daily-chemical industry.
