Naringenin (the aglycone of naringin) and naringin supplements, on the other hand, offer a host of valuable health benefits. Naringenin is found as "Naringin" which is an inactive form and converted into "Naringenin" by intestinal bacteria [22]. Naringenin's protective effect could be explained by its important role in preventing hydroxyl radical formation and protecting the integrity and functions of tissues, like other antioxidant elements [87, 88]. Dietary Supplement: Naringenin Other: Placebo. 161,162 Its aglycon is naringenin, which is synthesized by a shikimic acid pathway and occurs naturally in citrus fruits. Extraction by cold method 50 gm of grapefruit peel mat erial . (S)-naringenin is the (S)-enantiomer of naringenin. Early Phase 1. Harsh extraction conditions of CSE (hot, acidic and longer treatment time) might have resulted in a reduction in the recovery of phenolic compounds (Boluda-Aguilar & Lpez-Gmez, 2013). Naringin is a flavonoid glycoside that is abundantly contained in the skin of grapefruit and orange and is the origin of their bitterness.
