Abstract

Bu çalışmada, Türkiye'de lokal olarak yetiştirilen tatlı patates ve gölevez bitkilerinin farklı organlarının biyoaktif bileşenlerinin değişkenliğini ve dağılımını değerlendirmek amacıyla yürütülmüştür. Bu iki türün farklı organından (tatlı patatesin yumru ve yaprakları; gölevezin yaprakları, yaprak sapları, ana yumruları ve lateral yumruları) ekstrakte edilen örneklerde değerlendirmeler yapılmıştır. Çalışmada iki farklı türün ve örnek alınan organlarının toplam suda çözülebilir protein, toplam flavonoid, toplam fenolik, H2O2 giderme kapasitesi, toplam karotenoid, FRAP antioksidan kapasitesi, CUPRAC antioksidan kapasitesi ve toplam kuru madde parametreleri ölçülmüştür. İncelenen tüm parametreler için organ ortalamaları arasındaki fark istatistiksel olarak anlamlı bulunmuştur. Genel olarak her iki türün yaprakları toplam kuru madde ve CUPRAC antioksidan kapasitesi dışındaki tüm parametreler için en yüksek içeriğe sahip bulunmuştur. Ayrıca parametrelerin gen havuzundaki varyasyonu açıklamadaki etkinliği temel bileşenler analizi kullanılarak incelenmiştir. H2O2 giderme kapasitesi, toplam kuru madde içeriği ve CUPRAC antioksidan kapasitesi dışındaki tüm parametreler varyasyona yüksek katkı yapmıştır. Elde edilen bulgulara göre, bu iki tür ve organları arasında yüksek varyasyon olduğu anlaşılmıştır. Bu sonuçlar, ileride bu iki tür ile ilgili yapılacak çalışmalara yol gösterici olacaktır.

Some Bioactive Components of Sweet Potato and Taro: A Comparative Study Based On Plant Organs

Abstract

This study was carried out to evaluate the variability and distribution of bioactive components of different organs of sweet potato and taro plants grown locally in Turkey. Samples extracted from different organs of these two species (tubers and leaves of sweet potato; leaves, petioles, main tubers, and lateral tubers of taro) were evaluated. Total water-soluble protein, total flavonoids, total phenolics, H2O2 scavenging capacity, carotenoids, FRAP antioxidant capacity, CUPRAC antioxidant capacity, and total dry matter parameters of two different species and their organs were measured. The difference between the organ averages for all parameters examined was statistically significant. In general, leaves of both species had the highest content for all parameters except total dry matter and CUPRAC antioxidant capacity. The effectiveness of the parameters in explaining variation in the gene pool was also examined using principal component analysis. All parameters contributed highly to the variation except H2O2 capacity, total dry matter content, and CUPRAC antioxidant capacity. According to the findings, there is a high variation between each species and between the organs. These results will guide future studies on these two species.
