. Antioxidants become more and more frequently used in order to maintain homeostasis of the organism and diminish the risk of disease. Herein, we introduce some antioxidant preparations of natural plant origin (Rhodiola, Aloe vera, Resveratrol, Echinacea, Plumbagin) and antioxidant supplements (Padma 28

behind the cause and the development of the disease. Increasing evidences have shown that reactive oxygen species (ROS) and reactive nitrogen species (RNS) play important roles in the initiation and progression of heart disease. The potential of using antioxidants, especially the natural antioxidants

evaluated as oxidation parameters in beef hamburgers during 90 days ’ storage. The addition of 0.01 % yerba maté ethanolic extracts proved inefficient in restraining the lipid peroxidation while the addition of 0.1 % resulted in efficient antioxidant activity. Sensory evaluation of hamburger containing 0

to that produces by different concentrations of Butylated hydroxyanisole (BHA) and Butylated hydroxytoluene (BHT). Peroxide value (PV) and anisidine value (AnV) measurement in sauce indicated that all concentrations of EO had antioxidant effect in comparison to synthetic antioxidants. Samples added with EOs at 0

ABSTRACT Different species of ferns were analyzed for the modulations in the pool of non-enzymatic antioxidants in response to the maleic hydrazide treatments. Treatments at very low doses were found to trigger the accumulation of both ascorbate and proline contents. Total amount of protein

according to the Folin-Ciocalteu procedure and calculated as gallic acid equivalents. Antioxidant activity of methanolic extracts was determined by using the Oven (63°C) and Rancimat (90,120,150°C) methods on refined soybean oil and compared with the effects of synthetic antioxidants ( BHA, BHT and TBHQ

kullanımı Bu derlemenin amacı, koruyucu ve tedavi edici tıp içerisinde skualenin yerini ve önemini vurgulamaktır. Skualen bir triterpen olup, hemoglobinden bağımsız olarak oksijeni hücreye doğrudan taşıyarak tüm vücuda ulaştırabilmektedir. Skualenin kanser oluşumunu önlediği ve yüksek anti-tümör aktivitesine sahip olduğu bildirilmiştir, bu nedenle, çeşitli kanserlerin tedavi sürecinde destekleyici olarak kullanılabilmektedir. Skualenin bu konu ile ilgili epidemiyolojik ve deneysel hayvan araştırmaları ilginç ve umut vericidir. Bununla birlikte, skualenin kimyasal özellikleri nedeniyle farklı hastalıkların tedavisinde kullanılması açısından, insanlarda daha geniş çalışmalarla desteklenmesi gerekmektedir. Anahtar sözcükler: Skualen, triterpen, sitotoksik aktivite, anti-tümor aktivite, deri hastalıkları, kolesterol metabolizması
