dc.description.abstract | I n this study, two grams of callus regenerated from stem and leaf explants of Astragalus trojanus Stev. were cultured in Woody Plant Medium (WPM) supplemented with 1 mg/L 2,4-D for four weeks and used as inoculum in order to investigate the effects of working volume and media composition. The highest biomass was obtained in 250 mL flask with astragaloside IV (1.66 µg/mg) and cycloastragenol (0.19 µg/mg) accumulation. Different concentrations of sucrose and casein hydrolysate (1 and 2 g/L) were also tested and the effect of pH was also investigated. Biomass accumulation cannot be enhanced, however, astragaloside IV and cycloastragenol content was ascended. The highest astragaloside IV (95.23 µg/mg) and cycloastragenol (5.93 mg/mg) accumulations were obtained at pH 6.8 and 2 g/L casein hydrolysate, respectively | en_US |
dc.description.abstract | Bu çalışmada, Astragalus trojanus Stev. gövde ve yaprak eksplantlarından elde edilen iki gram ağırlığında kalluslar 1 mg/L 2,4-D içeren Woody Plant Medium (WPM) besin ortamında dört hafta boyunca kültüre alınmışlar ve çalışma hacminin ve besin ortamının etkilerinin incelenmesi için başlangıç materyali (inokulum) olarak kullanılmışlardır. En fazla biyokütle astragaloside IV (1.66 µg/mg) ve cycloastragenol (0.19 g/mg) içeriğiyle 250 ml’lik erlenden elde edilmiştir. Farklı konsantrasyonlarda sükroz ve kazein hidrolizat (1 ve 2 g/L) denemeleri yapılmış ve pH’ın etkisi de incelenmiştir. Biyokütle birikiminde artış sağlanamamış ancak astragaloside IV ve cycloastragenol içerikleri artmıştır. En yüksek astragaloside IV (95.23 µg/mg) ve cycloastragenol (5.93 µg/mg) içerikleri pH 6.8’de ve 2 g/L kazein hidrolizat denemesinde elde edilmiştir. | en_US |
