Nutritional and nutraceutical characteristics of Sageretia theezans fruit

Abstract

The fruit of Sageretia theezans is one of many underutilized edible fruits that grow along the southern seashores of East Asia. In this study, to evaluate the nutritional and nutraceutical values of S. theezans fruit, the composition of minerals, organic acids, and proximate and fatty acids, the total phenolic, total flavonoid, and total anthocyanin content, and the antioxidant and antidiabetic activities of S. theezans fruit were analyzed. The results indicate that S. theezans fruit could be classified as a potential potassium-, malic acid-, and linoleic/oleic acid-rich fruit. In addition, The ethyl acetate (EtOAc) fraction of the 70% ethanol (EtOH) crude extract exhibited strong antioxidant activities including free radical scavenging and reducing power activities compared with the same concentration of butylated hydroxytoluene. Furthermore, the EtOAc fraction showed significant inhibition of α-glucosidase activity. The analysis of the total phenolic and flavonoid content suggested that the remarkable antioxidant and antidiabetic activities of the EtOAc fraction are due to the presence of high levels of polyphenolic compounds.

Sageretia theafruit extracts rich in methyl linoleate and methyl linolenate downregulate melanogenesis via the Akt/GSK3β signaling pathway

“…The fruits of Sageretia thea are purple and contain micronutrients [ 24 ]. Sageretia thea fruits contain a much higher level of anthocyanins than do blueberries [ 24 36 ].…”

“…The fruits of Sageretia thea are purple and contain micronutrients [ 24 ]. Sageretia thea fruits contain a much higher level of anthocyanins than do blueberries [ 24 36 ]. Anthocyanins are beneficial bioactive flavonoids known to reduce melanin production and mushroom tyrosinase inhibitory activity in α-MSH-stimulated B16F10 cells [ 37 ].…”

“…Thus, whitening agents from natural sources are preferred and tend to dominate the cosmetic market [ 21 ]. Sageretia thea , belonging to the Rhamnaceae family, has long been recognized as a medicinal herb in Korea and China [ 22 23 24 25 ]. Several studies have demonstrated that the leaves of Sageretia thea have antioxidant activity [ 22 23 ] and have been used to treat itching, boils, and inflammation of the skin caused by lacquer poison in China [ 25 ].…”

Sageretia thea (Osbeck.) modulated biosynthesis of NiO nanoparticles and their in vitro pharmacognostic, antioxidant and cytotoxic potential

“…Sageretia thea belongs to the rhamnaceae family [23]. The medicinal uses of S. thea (Bird Plum/English) are well documented and it is mostly used in the treatment of jaundice, hepatitis, circulatory and cardiovascular disease [23][24][25]. Biosynthesis of NiO nanoparticles has been successfully demonstrated in recent years and therefore there is a growing interest in NiO nanoparticles synthesis via green route.…”

Extracts from Sageretia thea reduce cell viability through inducing cyclin D1 proteasomal degradation and HO-1 expression in human colorectal cancer cells

“…As one of the Rhamnaceae family, Sageretia thea ( S. thea ) has been commonly known as Chinese sweet plum or Chinese bird plum [29]. S. thea as traditional herbal medicine has been treated for hepatitis and fevers in Korea and China [29, 30]. In pharmacological study, the fruits from S. thea have been reported to exert anti-oxidant, anti-diabetes and anti-melanogenesis activity [30, 31].…”
