“…Physical and chemical method including firmness and microbial are used effectively to determine the quality condition of kiwifruit. Some new instrument detection methods with accurate analysis ability such as GC, GC-MS, HPLC, UPLC-QqQ-MS/MS, and electronic nose combined with surface acoustic wave resonator are developed for the fruit and its products quality rapid analysis (Kvesitadze et al, 2001; Montefiori et al, 2005; Liu and Hui, 2015; Jiao et al, 2019). As to radix A. chinensis , the systematical method like UPLC-TOF/MS and UPLC-QqQ/MS is commonly applied to quality evaluation and active components analysis for A. chinensis (Zhao et al, 2014).…”

Actinidia chinensis Planch. (A. chinensis), commonly known as Chinese kiwifruit, is a China native fruit, which becomes increasingly popular due to attractive economic, nutritional, and health benefits properties. The whole plant including fruits, leaves, vines, and roots of A. chinensis are used mainly as food or additive in food products and as folk medicine in China. It is a good source of triterpenoids, polyphenols, vitamin C, carbohydrate, amino acid, and minerals. These constituents render the A. chinensis with a wide range of pharmacological properties including antitumor, antioxidant, anti-inflammatory, immunoregulatory, hypolipemic, antidiabetic, and cardiovascular protective activities, suggesting that it may possibly be value in the prevention and treatment of pathologies associated to cancer, oxidative stress, and aging. This minireview provides a brief knowledge about the recent advances in chemistry, biological activities, utilization, and storage of Chinese kiwifruit. Future research directions on how to better use of this crop are suggested.

“…Figure 3 shows the chromatograms of the mixed standards and the phenolic profiles of ‘Jinfeng’ kiwifruit. The content of ascorbic acid of ‘Jinfeng’ kiwifruit was 7.21 ± 0.08 mg/g DW, which was 20% higher than that of ‘Hayward’ kiwifruit ( Actinidia deliciosa ) (5.63 mg/g DW), and 40% higher than that of other Actinidia chinensis cultivars (4.27–4.34 mg/g dry mass) [ 61 , 62 ]. The differences in ascorbic acid content in kiwifruit might be due to the diversity of species and cultivars [ 16 ].…”

Kiwifruit (Actinidia chinensis) is a nutrient-dense fruit abundant in vitamin C and phenolic compounds, and it exhibits strong antioxidant capacity. However, the antioxidants in ‘Jinfeng’ kiwifruit have seldom been extracted and analyzed, and the conditions for the extraction of kiwifruit antioxidants by ultrasound-assisted extraction (UAE) have seldom been investigated. In this study, response surface methodology (RSM) was used to optimize UAE conditions to extract antioxidants from ‘Jinfeng’ kiwifruit. In addition, the antioxidant capacity, contents of total phenolics and total flavonoids, ascorbic acid, and the profiles of antioxidants were also analyzed. The results showed that the optimal UAE conditions included 68% ethanol, liquid/solid ratio at 20 mL/g, extraction time at 30 min, extraction temperature at 42 °C, and ultrasonic power at 420 W. Under these conditions, the ABTS value of kiwifruit was 70.38 ± 1.38 μM TE/g DW, which was 18.5% higher than that of the extract obtained by conventional solvent extraction. The total phenolic and flavonoid contents were 15.50 ± 0.08 mg GAE/g DW and 5.10 ± 0.09 mg CE/g DW, respectively. Moreover, 20 compounds were tentatively identified by UPLC–MS/MS, and the content of main compounds, such as procyanidin B2, neochlorogenic acid, and epicatechin, were determined by HPLC-–. This research revealed the profiles of antioxidant phytochemicals in ‘Jinfeng’ kiwifruit, which can be a good dietary source of natural antioxidants with potential health functions.

“…The fruits were first measured to determine the horizontal and vertical diameter (for shape index) and single fruit weight, then 50 fruits were randomly selected to determine the hardness; the remaining 50 fruits were tested for the Vc content, total solubility solids (TSS), Titratable acids (TA) and TSS/TA ratio, as well as the mineral and trace element content. The vitamin C concentration was determined by High-Performance Liquid Chromatography [28], the TSS was measured with a digital refractometer (PAL-1, Atago, Tokyo, Japan) with juice drops, the TA were determined by using an acid-base titration method based on CNS GB/T 12456-2008 [29], and mineral and trace element content were determined by the national standard GB 5009.268-2016 [30].…”

The application of the plant growth regulator 1-(2-chloro-4-pyridyl)-3-phenylurea (CPPU) is extensively used for red-fleshed kiwifruits or ‘Donghong’, but it has toxicological properties. Extra plant growth regulators (PGRs) were screened for partial substitution of CPPU (10 mg L−1) to the crops to minimize the CPPU content. The results showed that CPPU at a concentration of 5 mg L−1 plus 14-hydroxylated brassinosteroid (14-OH BR) at a concentration of 0.15 mg L−1 has a nearly equal effect to CPPU at a concentration of 10 mg L−1; it maintains the kiwifruit yields and quality as well as increases the postharvest time. Transcriptome sequencing data revealed that the regulation of 14-OH BR on kiwifruit growth acts mainly by activating Brassinosteroid (BR) signaling to synergistically and antagonistically stimulate the signaling of other endogenous growth regulators, including auxin (IAA), abscisic acid (ABA), cytokinin (CK), gibberellin (GA), jasmonic acid (JA) and ethylene (ET).
