Abstract

The present invention relates to a method for mass-production of viniferin using stevioside from cell culture of grape tree tissue. Viniferin is known to be effective for protection of liver, anticancer, antioxidant, and skin whitening, have an effect of inhibiting oxidation of low-density lipoprotein and high-density lipoprotein and inhibiting the proliferation and migration of vascular smooth muscle cells. Therefore, the present invention is very useful for the mass production of viniferin among the useful substances (stilbene compounds) from a callus derived from the anther tissue of the grape plant, which is very important for the related industries.

Claims (12)

1. A method of mass production of viniferin derived from a grape tree, the method comprising the steps of:

(a) transplanting a grape tree tissue fragment on a callus induction medium to induce a grape tree callus;

(b) culturing the induced grape tree callus in a growth medium to grow; and

(c) adding an activity-inducing agent and a solubilizing agent to the grown callus, followed by shaking culture,

wherein the activity-inducing agent and the solubilizing agent in step (c) are methyl jasmonate and stevioside, respectively;

the methyl jasmonate and stevioside are added at a concentration of 50 μM to 350 μM and 40 mM to 60 mM, respectively; and

the viniferin is delta (δ)-viniferin or epsilon (ε)-viniferin.

2. A method of mass production of resveratrol derived from a grape tree, the method comprising the steps of:

(a) transplanting a grape tree tissue fragment on a callus induction medium to induce a grape tree callus;

(b) culturing the induced grape tree callus in a growth medium to grow; and

(c) adding 50 μM to 350 μM methyl jasmonate (MeJA) and 40 mM to 60 mM stevio side to the grown callus, followed by static culture.

3. The method according to claim 2 , wherein the static culture is performed at 24° C. to 26° C. for 4 days to 7 days.
