“…This result suggested that the difference of TFC in the pulp between wild and local varieties may be caused by long-term domestication of citrus. TFC in peels were higher than pulps had been proved in previous studies [6,29]. In the current study, pulps of lemon (C. limonia) and kumquat (F. crassifolia) appeared a relatively higher TFC than those of in their peels (Table 1).…”

“…Ponkan [42]. Nobiletin proved to be the most dominant PMF in sweet orange and mandarin [6], and it ranged from 150.35 to 1137.05 mg/100 g DW in the present study, which was significantly higher than the content reported by Xing, et al [43]. Meanwhile, mandarin peels were also the good source of tangeretin and senensetin.…”

“…The extraction of flavonoids was performed, as described in the previous study [6]. Briefly, sample (peel 0.40 g, pulp 0.40 g, or juice 2 mL) was put into a 10 mL centrifuge tube and extracted with 8 mL anhydrous ethanol for 30 min in ultrasound (300 W) at room temperature.…”

“…In recent years, Citrus fruits have been suggested to be a good source of dietary antioxidants and their role in the prevention and treatment of various diseases were widely studied [4]. The major phenolic compounds found in citrus are flavonoids, which are considered to be one of the most important sources of bioactive compounds [5,6].…”

“…However, Citrus ichangensis and Citrus limonia have been scarcely studied. Previous studies showed that the flavonoid types and contents in citrus fruits varied due to different species and cultivars [6], and their distribution in different fruits tissues [24]. Naringin was the dominant compound in the peel of pummelo (C. grandis), while mandarin (C. reticulata) was rich in hesperidin [25][26][27].…”

Flavonoid profile and antioxidant activity of citrus peels, pulps, and juices from 27 local citrus cultivars in China were investigated. Flavonoid composition and content were determined using UPLC-PDA. Total phenolic content (TPC) and total flavonoid content (TFC) were measured using a Folin–Ciocalteau reagent and Al(NO3)-NaNO2 complexometry, respectively. The antioxidant capacities of the extracts were evaluated by DPPH, ABTS and FRAP method, respectively. Citrus peel not only exhibited better antioxidant potential, but also presented more composition diversity and contained higher concentrations of flavonoids than pulp and juice. Different citrus species were characterized by their individual predominant flavonoids, contributing largely to the antioxidant activity, such as mandarin was characterized by hesperidin, nobiletin and tangeretin, while pummelo and papeda were characterized by naringin. The peel of Guihuadinanfeng (Citrus reticulata) had the highest TPC of 23.46 mg equivalent gallic acid/g DW (dry weight) and TFC of 21.37 mg equivalent rutin/g DW. Shiyueju (C. reticulata) peel showed the highest antioxidant capacity based on the antioxidant potency composite (APC) analysis. Overall, mandarin (C. reticulata) fruits peel contained more TPC and TFC, exhibiting higher antioxidant capacities than other species, and were good natural sources of flavonoids and antioxidants.

Flavonoids are the representative active substances of citrus with various biological activities and high nutritional value. In order to evaluate and utilize citrus flavonoids, isolation and purification are necessary steps. This manuscript reviewed the research advances in the extraction and purification of citrus flavonoids. The structure classification, the plant and nutritional functions, and the biosynthesis of citrus flavonoids were summarized. The characteristics of citrus flavonoids and the selection of separation strategies were explained. The technical system of extraction and purification of citrus flavonoids was systematically described. Finally, outlook and research directions were proposed.
