A research on the detection of some phytochemical properties in the fruits of passiflora species

Passiflora belongs to the Passifloraceae family and is native to South Africa. Thanks to its health benefits, it is now commonly grown in tropical and subtropical regions. This fruit gathers attention, especially for its rich nutritional content, aroma, and taste. Passiflora has gained popularity in the Mediterranean region of Turkey, particularly in recent years. It stands out for its ease of maintenance, yielding twice a year, and high economic returns. Additionally, passiflora is used as an ornamental plant in landscaping arrangements by means of its showy flowers and is often referred to as the “passionflower” or “clock flower”. In this study, the fruits of P. edulis and P. caerulea species were examined for their phytochemical properties, such as DPPH, total phenol, sugar, and organic acid. DPPH (2,2‐diphenyl‐1‐ picryl‐hydrazyl‐hydrate) and total phenol were analyzed using a spectrophotometric method, while sugar and organic acid were analyzed using HPLC

DETERMINATION OF TOTAL PHENOL AND ANTIOXIDANT ACTIVITY OF SOME BERRIES

Dünyada ve ülkemizde son yıllarda fenol bileşikleri ve antioksidan içerikleri nedeniyle üzümsü meyvelerin üretim ve tüketiminde büyük oranda artışlar meydana gelmiştir. Meyveler içerisinde özellikle üzümsü meyveler doğal antioksidanlarca zengin olup yüksek antioksidan kapasiteye sahiptirler. Bu çalışmada bazı üzümsü meyvelerin toplam antioksidan aktivitesi ve toplam fenolik madde içeriği araştırılmıştır. "Chester Thornless" böğürtlen çeşidinde toplam fenol içeriği 338.82 mgGAE/100 g ext, "Bluecrop" mavi yemiş çeşidinde 79.32 mgGAE/100g ext, "K60"nolu dut tipinde 482.62 mgGAE/100gext, "K68" no'lu dut tipinde 572.92 mgGAE/100gext, "K45" no'lu dut tipinde 498.49 mgGAE/100gext, "P1" nolu dut tipinde 680.34 mgGAE/100gext, "A5" no'lu dut tipinde 120 mgGAE/100gext ve "S7" no'lu dut tipinde 229.5 mgGAE/100gext olarak belirlenmiştir. Antioksidan aktivite içerikleri incelendiğinde "Chester Thornless" böğürtlen çeşidinde toplam antioksidan içeriği %60.73, "Bluecrop" maviyemiş çeşidinde %38.25, farklı dut tiplerinde ise (K60) %44.73, (K68) %51.86, (K45) %57.05, (P1) 50.38, (A5) %32.84, (S7) %73.28 olarak belirlenmiştirIn recent years, production and consumption of berry fruits has been increasing in the world and also in our country due to their antioxidant content. Fruits especially berries are known as natural antioxidants because of having high antioxidant capacity. In this study, antioxidant activity and total phenolic content of some berry fruits were compared. Total phenols was detected in “Chester Thornless” as 338.82 mgGAE/100gext, in “Blue Crop” blueberry variety as 79.32 mgGAE/100gext, in mulberries, 482.62 mgGAE/100gext for “K60”, 572.92 mgGAE/100gext for “K68”, 498.49 mgGAE/100gext, for “K45”, 680.34 mgGAE/100gext for “P1”, 120 mgGAE/100gext for “A5” and 229.5 mgGAE/100gext for “S7”. Antioksidan activities of berry fruits were detected in “Chester Thornless” blackberry variety as %60.73, in “Blue Crop” blueberry variety as %38.25 and in various 1 Prof. Dr. Çukurova Üniversitesi, Ziraat Fakültesi, Bahçe Bitkileri Bölümü, ADANA 2 Zir.
