Antioxidant Capacity, Vitamin C and Polyphenol Profile Evaluation of a By-Product Extract Obtained by Ultrasound Using Eutectic Solvent.

Habanero pepper leaves and stems (by-products) have been traditionally considered waste; however, bioactive compounds such as polyphenols, vitamin C and carotenoids have been identified that can be used for formulation of nutraceuticals or functional foods. Furthermore, the extraction of these bioactive compounds by using environmentally friendly methods and solvents is desirable. Thus, the aim of this study was to assess the antioxidant capacity, total polyphenol content (TPC), the phenolic profile and vitamin C content in extracts obtained from by-products (stems and leaves) of two varieties (Mayapan and Jaguar) of habanero pepper by ultrasound-assisted extraction (UAE) using natural deep eutectic solvents (NADES).

Polyphenols Content in Fruits at Different Harvest Times and Their Correlation with the Antioxidant Activity.

The aim of this work was to investigate the changes of the content of polyphenols in fruits of Jacq. at different harvest times and their correlation with the antioxidant activity. Habanero pepper plants grown in black soil (Mayan name: ) and harvested at 160, 209, 223, 237 and 252 post-transplant days (PTD) were analyzed.
