  author={Eucharia Oluchi Nwaichi and Lawrence C. Chuku and Ntongha Oyibo},
Consumption of fruits and vegetables containing antioxidants has been reported to provide protection against a wide range of degenerative disease including ageing, cancer, diabetes and cardiovascular disease (Ulbricht and Basch, 2005). The defensive effect of these natural antioxidants in fruits and vegetables are related to three major groups, vitamins, phenolics and carotenoids. Beta carotene and lycopene are carotenoids and they are known as lipophilic antioxidants (Halliwell, 1996). Food is… 
Effect on lycopene, β-carotene, ascorbic acid and phenolic content in tomato fruits infected by Alternaria alternata and its toxins (TeA, AOH and AME)
The results concluded that A. alternata mostly affects the nutritional values of tomato fruits due to the combined effect of the toxins.
Nutritional and Antioxidant Potential of Functional Ingredient
There are innumerable fruits which are consumed for their nutritional and medicinal potential. Bioactive constituents present in various fruits act as radical scavengers and helps in preventing non
Comparative Analysis of Ascorbic Acid Content and Antioxidant Activity of Some Fruit Juices in Syria
Fruits are considered essential constituents of a healthy diet. They possess antioxidant properties which can be attributed to the presence of antioxidant compounds. Ascorbic Acid (AA) is a water
Phenolic compounds and antioxidant and antibacterial activities of Algerian honeys

Extending Shelf Life of Guava Fruits by Mint oil and UVC Treatments
UVC (ultraviolet rays type C) and coating with mint oil were used to disinfest guava from fruit flies at ambient temperature and revealed the edge of mint oil coating over UVC and the untreated lots.
Antioxidant Vitamins in Honey Samples from Different Floral Origins and Altitudes in Asir Region at the South-Western Part of Saudi Arabia
There was significant increase in vitamin C concentration in ziziphus honey with the increase of the altitude, while an insignificant decrease was obtained in the case of vitamin A, and Regarding the effect of altitude on the concentration of vitamin C in the Acacia honey, there wassignificant increase in the honey from the altitude of 2247 compared to the Honey from all the other altitudes.

Antioxidant properties of several tropical fruits: A comparative study
Abstract Nine tropical fruits were analyzed for total phenol contents, ascorbic acid contents and antioxidant activities. The antioxidant activities were evaluated based on the ability of the fruit
The effect of heat processing on triterpene glycosides and antioxidant activity of herbal pegaga (Centella asiatica l. Urban) drink
The health benefit of herbal pegaga drink, which is associated with triterpene glycosides content and antioxidant activity attract a lot of interest from the public and food and herbal industries.
Carotenoid content and in vitro bioaccessibility of lycopene from guava (Psidium guajava) and watermelon (Citrullus lanatus) by high-performance liquid chromatography diode array detection
It can be concluded that guava can be used as a better lycopene source than watermelon and that the in vitro accessibility of lycopenes in guava is more than that in watermelon.
Tomatoes, tomato products and lycopene in the prevention and treatment of prostate cancer: do we have the evidence from intervention studies?
Increasing evidence suggests that a single serving of tomatoes or tomato products ingested daily may contribute to protect from DNA damage, as DNA damage seems to be involved in the pathogenesis of prostate cancer.
Regulation and function of ascorbate peroxidase isoenzymes.
It is clear that a high level of endogenous ascorbate is essential effectively to maintain the antioxidant system that protects plants from oxidative damage due to biotic and abiotic stresses.
