Abstract: We studied the influence of nitric oxide (with sodium nitroprusside used as the donor) and methyl jasmonate on the baicalin formation in and growth of suspension cultures of Scutellaria baicalensis cells. Nitric oxide could not enhance the accumulation of baicalin, but low concentrations promoted cell growth. Methyl jasmonate greatly enhanced the accumulation of baicalin and restricted the growth of cells. Maximal baicalin production was achieved with 0.05 mmol.L-1 sodium nitroprusside and 10 μmol.L-1 methyl jasmonate added at days 0 and 8, respectively; fresh weight and total baicalin yield was 1.2- and 2.96-fold higher, respectively, than in untreated cell cultures.
