Phenolic Profiles of Vitis davidii and Vitis quinquangularis Species Native to China

Abstract

The accumulation of phenolics in the skins of two Vitis davidii cultivars ('Ziqiu' and 'Xiangzhenzhu') and one Vitis quinquangularis cultivar ('Xiangshan No. 4') native to China was followed during ripening. It was found that the anthocyanin composition of all three grapes was dominated by anthocyanidin 3,5-O-diglucosides. The cultivar 'Xiangshan No. 4' (V. quinquangularis) contained a high level of 3',4'-substituted anthocyanins and low levels of flavonols and 3',4'-substituted flavan-3-ols, indicating that the F3'H branch pathway was the principal carbon pathway synthesizing mainly 3',4'-substituted anthocyanins. No myricetin-type flavonols were found in this cultivar, but in both 'Ziqiu' and 'Xiangzhenzhu' (V. davidii) cultivars the F3'5'H branch pathway was dominant, resulting in malvidin-based diglucoside anthocyanins. Cyanidin-based and petunidin-based anthocyanins were not detected in the 'Ziqiu' cultivar. Principal component analysis revealed that V. davidii grapes had abundant flavonols by the early middle developmental stages and a high level of malvidin-type anthocyanins by the late developmental stage. In contrast, the V. quinquangularis cultivar contained other anthocyanins instead of malvidin-type anthocyanins.

Comparison of non‐anthocyanin polyphenol accumulation in the berry skins of muscadine and European grapes during ripening in China

“…This is considered a beneficial trend in the native V. davidii (“Ziqiu” and “Xiangzhenzhu”) and V. quinquangularis (“Xiangshan No. 4”) species in China (Liang et al, ). Flavonols from muscadine grapes have a qualitatively different pattern to the two V. vinifera studied here and comprised mostly of a series of 3′,4′,5′‐type flavonols followed by 3′,4′‐type (e.g., 44.8%–72.6% and 23.1%–40.1% of total flavonol in 2014, respectively).…”

Transcriptome analysis of genes involved in anthocyanins biosynthesis and transport in berries of black and white spine grapes (Vitis davidii)

“…However, in our research, 3,5- O -diglucoside anthocyanins was the predominant anthocyanins in V. davidii . The studies have shown that, the 3,5- O -diglucoside anthocyanins were usually detected in other Chinese wild grapes [5, 7, 55, 56]. Therefore, the V. davidii was closer to the other Chinese wild grapes from the perspective of the composition of anthocyanins.…”

“…In recent years, the research of anthocyanins in Chinese wild grapes has been carried out, and the profile of anthocyanins in Chinese wild grapes is significantly different from V. vinifera [5, 7, 54–56]. Generally, only 3- O -monoglucoside anthocyanins are detected in V. vinifera cultivars, and almost all of the cultivars of V. vinifera are devoid of pelargonidin-based anthocyanins.…”

“…Generally, only 3- O -monoglucoside anthocyanins are detected in V. vinifera cultivars, and almost all of the cultivars of V. vinifera are devoid of pelargonidin-based anthocyanins. However, in Chinese wild grapes (such as V. amurensis , V. davidii and V. quinquangularis ), the 3,5- O -disglucoside anthocyanins widely exist, and pelargonidin-based anthocyanins are detected in some wild species [5, 7, 55, 56]. The berry color of most Chinese wild grapes is black, except for the white-fruited varieties of V. davidii .…”

Accumulation Pattern of Flavonoids in Cabernet Sauvignon Grapes Grown in a Low-Latitude and High-Altitude Region

“…Three groups of flavonoids were isolated from the grape skins according to Liang et al (2013). For the extraction of anthocyanins, grape skin powder (0.5 g) was suspended in 10 mL of methanol containing 2% (v/v) formic acid.…”
