Thanks to the increased international demand for resveratrol in 2008,the domestic market presented a picture of prosperity.Currently,the price for resveratrol declined after the tight domestic supply in 2009.

   That phenomenon results from the substantialy increased manufacturers to supply resveratrol.Many companes told that they can supply resveratrol in September,2009.However,the production capcity and quality  are diverse.Some manufacturers have stable control for 50% resveratrol.Some manufacturers have stable control for 98% resveratrol.On the one hand,there is no significant increase for resveratrol demand,on the other hand,suppliers have a significant increase in a short time.The price for 50% resveratrol falls from more than 1000RMB/kg to 800RMB/kg(the lowest price,with no restrictions on emodin).The price for 98% resveratrol has dropped to below 3000RMB/kg.Some manufacturers offer 2900RMB/kg.(3% emodin).

   In addition to fierce competition in the plant extract industry, synthetic resveratrol suppliers can not be ignored.Synthetic resveratrol firms in China are looking for their own market share.The quoted price for synthetic resveratrol is 2750RMB/kg,presently.The close price is lower than this figure.It is understood that impurities can not be controlled stably.
