Fruits as nutraceuticals: A review of the main fruits included in nutraceutical patents

Fruits have relevant usefulness in the elaboration of nutraceutical compositions and, as it is considered a "natural medicine", its market has been growing exponentially each year. Fruits, in general, contain a large source of phytochemicals, carbohydrates, vitamins, amino acids, peptides and antioxidants that are of interest to be prepared as nutraceuticals. The biological properties of its nutraceuticals can range from antioxidant, antidiabetic, antihypertensive, anti-Alzheimer, antiproliferative, antimicrobial, antibacterial, anti-inflammatory, among others. Furthermore, the need for innovative extraction methods and products reveals the importance of developing new nutraceutical compositions. This review was developed by searching patents of nutraceuticals from January 2015 until January 2022 in Espacenet, the search database of the European Patent Office (EPO). Of 215 patents related to nutraceuticals, 43% (92 patents) were including fruits, mainly berries. A great number of patents were focused on the treatment of metabolic diseases, representing 45% of the total patents. The principal patent applicant was the United States of America (US), with 52%. The patents were applied by researchers, industries, research centers and institutes. It is important to highlight that from 92 fruit nutraceutical patent applications reviewed, 13 already have their products available on the market.

Predominance of Antioxidants in Some Edible Plant Oils in Ameliorating Oxidative Stress and Testicular Toxicity Induced by Malathion

Malathion (MAL) is an insecticide that has been linked to reproductive system damage in both humans and animals. In the present investigation, the antitoxic effects of coffee and olive oils on MAL-induced testicular dysfunctions were evaluated. MAL-intoxicated rats were supplemented with coffee and olive oils (400 mg/kg) for 7 weeks. Exposure to MAL resulted in statistically altered antioxidant enzymes and histopathological findings of necrotic seminiferous tubules and spermatogenetic arrest in rats after seven weeks of treatment. The effects of MAL intoxication on physiological and histopathological changes were improved by the use of these oils. Murine double minute 2 (MDM2) was found to interact well with chlorogenic acid and oleuropein, two compounds from coffee and olive oils, respectively. Coffee oil and olive oil were found to be promising therapeutic agents for MAL-induced testicular toxicity and oxidative damage.
