| Abstract In this study, effect of heat treatments (liquefaction at 55 °C for 12 h and pasteurisation at 90 °C 15 sec) on total phenolic content, antioxidant activity and phenolic compounds of astragalus and sunflower-cornflower honeys was investigated. Total phenol content and antioxidant activity of honeys were assessed by Folin-Ciocalteu and ABTS methods, respectively. Phenolic profile was determined by HPLC-DAD system. Only pasteurisation process had a significant impact on sunflower-cornflower honey with regard to total phenolic content and antioxidant activity. Protocatechuic, 4-hydroxybenzoic, caffeic, p-coumaric, and ferulic acids, rutin, kaempferol were detected in astragalus honey, while 2,5-dihydroxybenzoic, chlorogenic, caffeic, p-coumaric, and... |

| A callus induction and plant regeneration protocol was developed from leaf and petiole explants of the endemic Astragalus nezaketae. Explants were cultured on Murashige and Skoog medium (MS) supplemented with different plant growth regulators (PGRs) [?-naphthaleneacetic acid (NAA), benzyladenine (BA), 2,4-dichlorophenoxyacetic acid (2,4-D), kinetin (Kin), thidiazuron (TDZ)]. The combinations and concentrations of PGRs were shown significant variations for the frequency of callus formation, appearence of callus and the potential of callus differentiation. NAA x BA have been found highly affective in callusing and plant regeneration. Other PGRs have not resulted in callus differentiation for shoot formation. The highest number of shoots (6/explants) was... |
