Abstract





Antioxidant activity 13 different samples of
medicinal and aromatic plants of Centaury (Hypericum montbretii), Centaury (Hypericum bupleuroides), Blackthorn (Paliurus spina-christi Mill), including leaf, flower and stem, was
investigated using DPPH, FRAP and CUPRAC methods. Total flavonoid, total
phenolic amount and the antibacterial features of extracts from these herbs
were also determined. According to the obtained of antioxidant datas, except
for the result of total polyphenol assay, the dried leaves of Centuary (Hypericum montbretii) had the best
antioxidant property that was realized in all results. Accordingly test of
total polyphenol, the content of yellow flower of Centuary (Hypericum montbretii) herb
was measured as of 22.48±0.66 mg GAE /g dry herb sample and so this herb had
the highest total phenolic content. Antimicrobial activity tests were carried
out using disc diffusion methods with 12 microbial species and the most of them
displayed good-moderate antimicrobial and antifungal activity.

Özet


Tıbbi ve aromatik bitkilerden olan Kantaron (Hypericum montbretii ve Hypericum bupleuroides) ve karaçalı (Paliurus spina-christi Mill)
bitkilerinin yaprak, çiçek ve kök gibi kısımlarından oluşan 13 farklı örneğin
antioksidan aktivitesi DPPH, FRAP ve CUPRAC yöntemleri kulanılarak
incelenmiştir. Aynı zamanda bitki ekstraktların toplam fenolik ve toplam
flavonoid miktarları da ölçülmüş ve antimikrobiyal özellikleri de
belirlenmiştir. Antioksidan aktivite sonuçlarına göre tüm analizler içinde
(toplam polifenol miktar analizi hariç) en iyi aktivite Kantaron (Hypericum montbretii) bitkisinin kuru
yaprağında olduğu bulunmuştur. Toplam polifenol analizine göre ise en yüksek
aktivitenin 22.485±0.656 mg GAE /g değeri ile Kantaron’un (Hypericum montbretii) çiçek kısmına ait olduğu görülmüştür.
Antimikrobiyal analizler ise disk düfüzyon yöntemi kullanılarak yapılmış ve
bitki ekstraktlarının 12 tane test mikrorganizması üzerine etkisi
incelenmiştir. Bu sonuçlara göre bitkilerden çoğunun bakterilere ve mantar
suşlarına karşı iyi derecede aktivite gösterdiği gözlenmiştir.
