Abstract
The influence of various culture conditions on callus growth and maintenance was studied the callus derived from Ginkgo biloba L. leaves, which were grown on Murashige and Skoog (MS) medium supplemented with growth regulators; α-naphthaleneacetic acid (NAA), benzylaminopurine (BA) and kinetin. The optimal concentrations of growth regulator for callus induction were 10μM NAA with 5μM BA or 0.5μM kinetin in the light. In the dark condition, the optimal concentration of growth regulator was 10μM NAA with 0.5μM BA. In the light, MS medium supplemented with 100μM NAA and 5μM BA combination was the optimal for growth and maintenance of callus cultures. The suspension cultures were initiated with 1.5g of the callus derived from Ginkgo leaf disks on MS medium. The optimal concentration of growth regulator for maintenance of callus culture was 10μM NAA with 0.5μM BA or kinetin. To determine the production of the quercetin dehydrate and keamperol profiles from suspension callus was compared by HPLC analysis. In the leaf extract, the contents of quercetin dehydrate and keamperol were 0.072 and 2.24μg/20μl, respectively. The extract of callus contained 0.556 and 0.157μg/20μl, respectively. The free radical scavenging activity of methanolic extracts from induced callus was more effective than leaf extract. The callus extracts concentration of 0.2mg/ml was enough for 50% inhibition. The habituation was more effective in the dark culture condition than in the light one.
