The crude product orange-brown oil was purified by column chromatography on silica gel employing an elution gradient of ethyl acetate in n-hexane, affording the desired pure 1S,2S 3- benzyloxy tert-butyldimethylsilyl oxy phenyl 2,4-bis benzyloxy tert-butyldimethylsilyl oxy phenyl propane-1,2-diol as a very viscous colourless oil. Conclusion Our results suggest synergistic changes between the expression of synthetic genes and the accumulation of catechins.
