Secondary Metabolite of Horse Chestnut in Vitro Culture
Aescin in calli and embryoids obtained from both cotyledon and stem explants of Aesculus hippocastanum were investigated by HPLC. Determinations were carried out on tissues cultured in agarized medium supplemented with growth substances (2,4-dichlorophenoxyacetic acid; kinetin; 1-naphthaleneacetic acid). The results indicate that aescin was produced in all the analysed samples. The amount of active principle present in some samples was higher than that found in horse-chestnut seeds.
