Determination of Antioxidants in Oil Palm Leaves (Elaeis guineensis)

Abstract

Problem statement: Previous findings on the occurrence of water soluble antioxidants in palm oil has brought to the question on whether these compounds is also present in other parts of the oil palm; namely its leaves. Approach: It is now believed that the water soluble antioxidants are also present in other biomass of the oil palm, namely, the leaves. This study reported on the determination of the water soluble antioxidants in oil palm leaves. Results: The results showed the analyses of the antioxidants in oil palm leaves. Conclusion: This study is thus conducted to trace the availability of these antioxidants in the leaves of the oil palm of the Elaeis guineensis variety.

Relation of Serum and Semen Malondialdehyde and Total Anti-Oxidants with Sperm Parameters in Infertile Men

“…Because oxidative stress is a major cause of sperm DNA damage then antioxidants should have an important therapeutic role to play in the clinical management of male infertility (World Health Organization (WHO), 1999; Ismail et al, 2009). Study of aspects of oxidative stress help us to design better antioxidant trials in future, with emphasis on identifying (Makker et al, 2009) appropriate doses (Sharlip et al, 2002;Han et al, 2010) selecting the right populations ((Mancini et al, 2009) treating for optimal durations and (Golbidi and Laher, 2010) specific intracellular targeting mechanisms (Golbidi and Laher, 2010). Understanding the physiologic and pathologic effects of free radicals on sperm function will help in designing new and effective treatment strategies in male infertility (Jedrzejczak et al, 2005).…”

“…Infertility is a major clinical problem, affecting people medically and psychosocially. Statistics indicate that 15% of all couples in the United States are infertile and the male factor is responsible for 25 of these cases (Makker et al, 2009;Sharlip et al, 2002;Han et al, 2010). Infertility is associated with Oxidative Stress (OS), normally counterbalanced by different antioxidant systems (Mancini et al, 2009;Golbidi and Laher, 2010I).…”

Palm Yağı ve Sağlık Üzerine Etkileri

“…Palm yağından farklı olarak, palm çekirdek yağında bulunan palmitik asidin %13-23'ünün gliserolün ikinci karbonuna bağlı olduğu (9) ve bu pozisyondaki palmitik asidin emilim oranının daha yüksek olduğu belirtilmektedir (10). Palm yağı önemli miktarda α-, β-, γ-, δ-tokoferol ve tokotrienol, karotenoid, sterol ve koenzim Q10 içermektedir (11). Palm yağında 129-215 ppm α-tokoferol ve 262-437 ppm γ-tokotrienol bulunmaktadır (5).…”

Toxicological Evaluation of Palm Oil and Components

“…Koenzim Q10, endojen olarak sentezlenen ve çeşitli kimyasal süreçlerde görev alan bir provitamin ve antioksidandır. 35 Vücutta en yüksek konsantrasyonda bulunduğu organ kalptir. 36 Mitokondriyal membranın iç yüzeyinde elektron transferi için taşıyıcı işlev görmekte ve adenozin trifosfat üretiminde yaşamsal bir rol oynamaktadır.…”

“…37 Yaşın ilerlemesine bağlı olarak koenzim Q10 düzeyleri vücutta azalmaktadır. 35,37 Bunun dışında kalp yetersizliği, kardiyomiyopati ve kanser hasta-Tuğçe ÇETİN ve ark. J Lit Pharm Sci 2018;7(2):97-109 lığı bulunan kişilerde koenzim Q10 düzeylerinin azaldığı belirlenmiştir.…”
