Jujube has received more and more attention due to their nutritional value and pharmacological effects. This study evaluated the quality of different varieties of jujube by comparing the main active components and antioxidant activities of thirty-seven varieties of jujube through titration, UV spectrophotometry and High performance liquid chromatography (HPLC). The results revealed that there were differences in active components and antioxidant capacity among jujube cultivars. Among the thirty-seven varieties of jujube, Qingxuyuanzao (QXYZ) had the highest contents of total phenols and flavonoids, which were 16.33 mg GAE/g DW and 41.18 mg RE/g DW, respectively, and had the highest free radical scavenging (DPPH: 29.79 mg Vc/g DW; ABTS: 50.90 mg Trolox/g DW) and reducing abilities (62.13 mg Trolox/g DW). Correlation analysis indicated that the content of total flavonoids, total phenols and phenolic acid ((+)catechin, caffeic acid, rutin) in jujube had high positive correlation with antioxidant capacity. According to principal component analysis (PCA), the comprehensive scores of different varieties of jujube were calculated. The top five jujube varieties with comprehensive scores are 'QXYZ,' Suyuanling (SYL), Xiangzao (XZ), Dunhuangdazao (DHDZ) and Meimizao (MMZ). In this paper, the main active components and antioxidant capacity of thirty-seven jujube varieties have been studied, which provides a theoretical basis for jujube breeding and the development of active nutrients for jujube.

“…The leaf at fruit ripening stage of G. elwesii displayed the most antioxidant activity (Ay et al, 2018). G. transcaucasicus Fomin shoot extract revealed the considerable antioxidant and antimicrobial activity (Karimi et al, 2018). In this study, hexane-, dichloromethane-and ethyl acetate extracts of Galanthus krasnovii were investigated for antioxidant activity as well as total phenolic content.…”

Natural products have gained the great interest due to their broad spectrum of biological activities. Galanthus krasnovii was dried at shade then extracted with hexane, dichloromethane, and ethyl acetate successively. After removing of solvent by reduced pressure, crude extracts of each solvent were yielded. Antioxidant activity including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical cation and reducing power assays were carried out for each extract. Moreover, total phenolic content was determined. Total phenolic content of hexane-, dichloromethane-, and ethyl acetate extracts were found as 60.95 mg GAE/g extract, 71.90 GAE/g extract and 58.90 GAE/g extract respectively. Dichloromethane and ethyl acetate extract revealed the moderate antioxidant activity. ÖZDoğal ürünler geniş spektrumlu biyolojik aktivite göstermelerinden dolayı yoğun ilgi görmektedirler. Galanthus krasnovii gölgede kurutulduktan sonra sırasıyla hekzan, diklorometan ve etil asetat ile ekstrakte edildi. Düşük basınçta çözücü uzaklaştırıldıktan sonra her bir çözücünün ekstraktı elde edildi. Her bir ekstraktın, 1,1-difenil-2-pikralhidrazil(DPPH) radikal, 2,2'-azino-bis(3-etilbenzotiazolin-6sülfirik asit) (ABTS) radikal katyon ve indirgeme gücü antioksidan çalışmaları gerçekleştirildi. Ayrıca, ekstraktların toplam fenolik içerikleri belirlendi. Hekzan-, diklorometan-ve etil asetat ekstraktlarının toplam fenolik içerikleri sırasıyla 60.95 mg GAE/g ekstrakt, 71.90 GAE/g ekstrakt ve 58.90 GAE/g ekstrakt olarak belirlendi. Diklorometan ve etil asetat ekstraktları orta derece aktivite gösterdi. Citation:To cite this article: Erenler R, Genç N, Elmastaş M, Eminağaoğlu Ö (2019).

“…Further, in another study conducted on P. maritimum, Rokbeni et al (2016) reported that leaf samples were good radical scavengers. Moreover, Karimi et al (2018) showed that antioxidant capacity of the flower samples in G. transcaucasicus was higher than that of the bulb samples. In our study, antioxidant activity of the flower samples was higher than those of the leaf, bulb and root samples.…”

“…Recent studies have shown that the total amount of phenolic and flavonoids in species belonging to the family Amaryllidaceae received various values depending on the growth and development periods of plants (Ay et al, 2018), plant parts (Rokbeni et al, 2016), cultural practicesses, climate and environmental factors (Tkaidza et al, 2018). Karimi et al (2018) studied on G. transcaucasus and reported that the total phenolic and flavonoid content (4.45 and 2.67 mg QE g -1 DW respectively) was highest in shoot samples, which were followed by flower samples (3.85 and 2.26 mg QE g -1 DW, respectively) and bulb samples (3.41 and 1.06 mg QE g -1 DW). Ay et al (2018) reported that the total phenolic and flavonoid content of G. elwesii were mostly higher in bulb samples harvested during fruit ripening (42.63 and 58.63 mg QE g -1 DW, respectively), which was followed by leaf samples harvested during the same period (42.58 and 43.21 mg QE g -1 DW, respectively).…”

Galanthus elwesii Hook is a medically and economically important species that contains acetylcholinesterase inhibitory alkaloids galantamine and lycorine with well-known biological activities. In a field experiment, different plant parts of G. elwesii were harvested at three growing stages: flowering, post-flowering and fruit set. A comparative evaluation of maceration and ultrasonic-assisted extraction of galantamine and lycorine from these plant parts was implemented. The antioxidant activities and the contents of total phenolic and flavonoid of different plant parts were also investigated. The quantfication of galantamine and lycorine in the extracts was carried out by Reversed-phase High-Performance Liquid Chromatography. The HPLC analysis showed that ultrasonic-assisted extraction displayed higher quantities of galantamine, lycorine, total phenolic compounds and flavonoid and stronger antioxidant activity than maceration extraction. The highest amount of galantamine and lycorine was found in the root and leaf samples taken at fruit set as 89.27 and 23.20 µg g -1 , respectively. Further, the leaf and bulb samples of fruit formation yielded the highest total phenolic and flavonoid contents of 45.58 and 60.92 GAE g -1 DW, respectively. In addition, higher antioxidant activities were observed with the leaf and bulb samples harvested at the stage of fruit set.
