The aim of this study is to investigate the
antioxidant and antimicrobial properties of shoot and root parts of Astragalus diphtherites var. diphtherites (A. diphtherites) and Astragalus
gymnalopecias (A. gymnalopecias)
species which were subjected to solvent series having different polarity. Total
phenolic, total flavonoid, 2.2-diphenyl-1-picryl-hydrazyl (DPPH), metal chelating,
reducing power and hydroxy radicals scavenging activities of the extracts were
tested in order to determine antioxidant properties. While the highest amount
of total phenolic contents was obtained from the methanol extract in the shoot
part of A. diphtherites and from the acetone extract in the root part of it, it
was obtained from the methanol extract in the shoot part of A. gymnalopecias and from the ethyl
acetate extract in the root part of it. The highest amount of total flavonoids
and reducing power activities of A.
diphtherites and A. gymnalopecias
were obtained from the acetone extracts in the shoot part and from the ethyl
acetate extracts in the root part. While the highest DPPH radical scavenging
activity was determined in the methanol extract in the shoot part of A. diphtherites and in the acetone
extract in the root part of it, it was determined in the methanol extract in
the shoot part of A. gymnalopecias
and in the ethyl acetate extract in the root part of it. The highest metal
chelating activity was seen in the
methanol extracts that were obtained from shoot parts of the A. diphtherites,
and in the hexane extracts that were obtained from of the root part of it, whereas it was seen
in the methanol extracts that were obtained from the shoot and root part of the
A. gymnalopecias. The ethyl acetate extracts of the shoot and root part in both
species showed the highest hydroxyl radical scavenging activity. It was determined that
acetone and methanol extracts of the shoot part of A. gymnalopecias have
inhibition effect on the growth of Streptococcus
pyogenes

Bu çalışmanın amacı farkı polariteye sahip çözücü
serilerinden geçiren Astragalus diphtherites var. diphtherites (A. diphtherites) ve Astragalus
gymnalopecias (A. gymnalopecias) türlerinin gövde
ve kök kısımlarının antioksidan ve antimikrobiyal özelliklerinin
araştırılmasıdır. Antioksidan
özellikleri belirlemek için özütlerin total fenolik, total flavonoid, DPPH,
metal şelatlama, indirgeme gücü ve hidroksi radikalini söndürme aktiviteleri
test edildi. En yüksek total fenolik bileşen miktarı A. diphtherites’ de gövdede metanol, kökte ise
aseton özütünden elde edilirken A. gymnalopecias’ ta gövdede metanol kökte ise etil
asetat özütünde tespit edildi. A. diphtherites ve A. gymnalopecias’ ta en yüksek total flavonoid
miktarları ve indirgeme gücü aktiviteleri gövdede aseton kökte ise etil asetat
özütlerinden elde edildi. A. diphtherites için en yüksek DPPH radikalini söndürme aktivitesi, gövdede
metanol kökte ise aseton özütünde, A.
gymnalopecias’ ta gövdede
metanol kökte ise etil asetat özütünde tespit edildi. A. diphtherites’ te gövde kısmından elde edilen
metanol ve kök kısmından elde edilen hekzan özütleri, A. gymnalopecias’ ta ise gövde ve kök kısımlarının
metanol özütleri en yüksek metal şelatlama aktivitesi gösterdi. Her iki türde de gövde ve kök etil
asetat özütleri en yüksek hidroksil radikali söndürme aktivitesi gösterdi. A.
gymnalopecias’ın gövde
aseton ve metanol özütlerinin Streptococcus pyogenes’in büyümesi üzerinde inhibisyon
etkisine sahip olduğu tespit edildi
