The present paper aims to evaluate antihyperglycemic activity of methanol extract of Citrus limetta fruit peel (MECL) in streptozotocin-induced (STZ; 65 mg/kg b.w.) diabetic rats. Three days after STZ induction, diabetic rats received MECL orally at 200 and 400 mg kg(-1) body weight daily for 15 days. Glibenclamide (0.5 mg kg(-1) p. o.) was used as reference drug. Blood glucose levels were meas...

Satsuma mandarin (Citrus unshiu Marc.), Hallabong [(C. Marc. × C. sinensis Osb.)×(C. reticulata Blanco)], Cheonhyehyang [((C. unshiu×C. sinensis)×C. reticulata)×(C. reticulate×C. sinensis)], and Redhyang (citrus hybrid 'Kanpei), which are citrus hybrids, mostly consumed in Korea. The flavor of peel depends on the composition content volatile essential oils. Limonene, ?-terpinene, ?-myrcene, lin...

Citrus peel essential oils have an impressive range of food and medicinal uses. In the present study we investigated the variation in the yield and chemical composition of the essential oils isolated from fresh, ambient-, and oven-dried peels of three Citrus species namely Citrus reticulata (C. reticulata), Citrus sinensis (C. sinensis) and Citrus paradisii (C. paradisii). The hydro-distilled e...

Plants activate antioxidant defense mechanisms under stress, which help maintaining the structural integrity of cell components and possibly reduces oxidative damage.  Low temperature stress leads to the production of reactive oxygen species and oxidative damage to plants. In this study, the effect of putrescine and proline on reducing the production of reactive oxygen species and increasing th...

The mandarin horticultural group is an important component of world citrus production for the fresh fruit market. This group formerly classified as C. reticulata is highly polymorphic and recent molecular studies have suggested that numerous cultivated mandarins were introgressed by C. maxima (the pummelos). C. maxima and C. reticulata are also the ancestors of sweet and sour oranges, grapefrui...
