THE INFLUENCE of GERMINATION TIME on SDG LIGNAN, PHENOLIC and FLAVONOID CONTENTS of FLAXSEED (LINUM USITATISSIMUM L.) SPROUTS

Bu çalışmada, kahverengi ve sarı keten tohumlarının (Linum usitatissimum L.) ve filizlerinin SDG (sekoizolarikirezinol diglukosit) lignan, fenolik ve şavonoit içeri¤ine çimlendirme süresinin etkisi araştırılmıştır. Kahverengi ve sarı keten tohumlarında SDG lignan miktarı sırasıyla 13.76 ve 6.17 mg/g olmasına karşın çimlendirme işlemi tohumların SDG lignan içeri¤inde önemli bir azalmaya neden olmuştur. 13 günlük kahverengi keten tohumu filizleri en yüksek SDG lignan (0.72 mg/g) içeri¤ine sahipken sarı keten tohumu filizlerinde en yüksek SDG lignan 0.37 mg/g olarak 11. günde saptanmıştır. Keten tohumlarının yapısındaki serbest ve esterleşmiş fenolikler ve şavonoitler çimlendirme işleminden sonra ve 5-13 günlük çimlendirme süresince artmıştır ve kültürel çeşitlilik istatistiksel anlamda önemli bulunmuştur (P

KETEN TOHUMU FİLİZLERİNİN SDG LİGNAN, FENOLİK ve FLAVONOİT İÇERİKLERİNE ÇİMLENDİRME SÜRESİNİN ETKİSİ

In this study, the effect of germination time on SDG (secoisolariciresinol diglucoside) lignan, phenolic and flavonoid contents of brown and yellow flaxseeds (Linum usitatissimum L.) and their sprouts was investigated. SDG lignan content of brown and yellow flaxseeds were obtained as 13.76 and 6.17 mg/g dw respectively whereas, germination resulted in a noticable reduction of SDG lignan in seeds. 13-old-day brown flaxseed sprouts had the highest SDG lignan content (0.72 mg/g dw) whereas, the highest SDG lignan content was determined as 0.37 mg/g in yellow flaxseed sprouts at 11 days. Free and esterified phenolics and flavonoids were increased after with germination and during germination (5-13 days) and cultivar had a significant effect (P
