“…Hydroxyl groups in natural compounds are usually attached to the 3, 4, and 5 positions which cannot be exactly determined by MS. Therefore, on the basis of the mass spectra and previously published data, the peaks 6 , 8 , and 12 were tentatively identified as di- and mono-hydroxybenzoic acid derivatives [ 34 ]. All three compounds were detected and quantified in VOP recovered with water, the amount of 12 was eight-fold lower than reported by Velioglu et al [ 3 ].…”

“…VOP-E contained higher amounts of gambiriin (17), cinchonains (36, 37), and anthocyanins. phenolic compounds, which were not found in VOP-W, e.g., cinchonains (28,31), iridoids (7, 39, 42-45), (epi)catechin derivatives (20,27,34,40), quercetin derivatives (32, 33, 38), scopoletin-7-Osophoroside ( 14), and dihydromyrecitin [50] (29) and ethylchlorogenate (35).

“…It is interesting noting that despite no antiproliferative activity of VOP-W in HT29 cells its antioxidant activity in Caco-2 cells was similar. It may be assumed that the antiproliferative effects of antioxidant phytochemicals of VOP, due to structural peculiarities, may be achieved by different mechanisms, which are not directly related to In addition, the antiproliferative effect of VOP-E could be attributed to the presence of other phenolic compounds, which were not found in VOP-W, e.g., cinchonains (28,31), iridoids (7, 39, 42-45), (epi)catechin derivatives (20,27,34,40), quercetin derivatives (32, 33, 38), scopoletin-7-O-sophoroside (14), and dihydromyrecitin [50] (29) and ethylchlorogenate (35). The bioactivities of most of these phytochemicals have not been reported previously.…”

Defatted by supercritical CO2, Viburnum opulus berry pomace (VOP) was subjected to consecutive extraction with pressurized ethanol (E) and water (W) and yielded 23% of VOP-E and 8% of VOP-W, respectively. The major phytochemical groups covering 42 identified and quantified constituents in VOP extracts were organic and phenolic acids, iridoids, quercetin and (epi)catechin derivatives, flavalignans, procyanidins, and anthocyanins. The on-line HPLC-DPPH•-scavenging assay revealed the presence of numerous antioxidants. VOP-E had a higher total phenolic content, was a stronger antioxidant (equivalent to 0.77, 0.42, and 0.17 g trolox/g in oxygen radical absorbance capacity (ORAC), ABTS, and DPPH assays, respectively), and recovered the major part of phenolics from the pomace; however, both extracts demonstrated similar antioxidant activity in the cellular assay. VOP-E inhibited HT29 cancer cells at non-cytotoxic concentrations. The results of this study revealed that VOP contains valuable phytochemicals possessing antioxidant and antiproliferative activities. Consequently, extracts from VOP substances may be of interest in developing functional ingredients for healthy foods, nutraceuticals, and cosmeceuticals.

“…Oil makes up approximately 5%–6% of the seed cake, and the remaining seed cake after extraction can be used to extract 4% of high-quality saponin ( Zhu et al, 2018 ). Recent studies have shown that seed cakes contain large amounts of polyphenols and new saponins with antimelanogenic and hypoglycemic activity ( Zhang et al, 2012 ; Zhang and Li 2018 ; Hong et al, 2019 ). For example, kaempferol extracted from seed cakes shows excellent scavenging activity of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical ( Zheng et al, 2019 ), saponins show anticancer activity ( Di et al, 2017 ; Wang et al, 2019a ), and polysaccharides show hypoglycemic activity ( Zhang and Li 2018 ; Zhu et al, 2018 ; Jin et al, 2019 ).…”

Camellia oleifera is a woody oil tree species unique to China that has been cultivated and used in China for more than 2,300 years. Most biological research on C. oleifera in recent years has focused on the development of new varieties and breeding. Novel genomic information has been generated for C. oleifera, including a high-quality reference genome at the chromosome level. Camellia seeds are used to process high-quality edible oil; they are also often used in medicine, health foods, and daily chemical products and have shown promise for the treatment and prevention of diseases. C. oleifera by-products, such as camellia seed cake, saponin, and fruit shell are widely used in the daily chemical, dyeing, papermaking, chemical fibre, textile, and pesticide industries. C. oleifera shell can also be used to prepare activated carbon electrodes, which have high electrochemical performance when used as the negative electrode of lithium-ion batteries. C. oleifera is an economically valuable plant with diverse uses, and accelerating the utilization of its by-products will greatly enhance its industrial value.

“…Representative UPLC-QTOF-MS/MS total ion chromatograms (TIC) in the negative ion mode of polyphenols in CFG are shown in Figure 1. The phenolic compounds were tentatively identified by matching retention times (RT), m/z values, MS/MS fragments with compounds from the reported data in literature and database resources [21]. In addition, the relevant MS/MS spectra are provided in the Supplementary Materials.…”

Bamboo is a widely distributed graminaceous plant in China and is a potential source of bioactive substances. Incidentally, bamboo’s fruit is rich in phytochemicals such as polyphenols and flavonoids, which are significant to human health. In this study, we identified the phenolic compounds of the fruit and investigated the antioxidant activities of Cephalostachyum fuchsianum Gamble (CFG) fruit polyphenols with in vitro and in vivo tests for the first time. UPLC–Q–TOF–MS/MS analysis results showed that the fruit contained 43 phenolic compounds, including 7 hydroxybenzoic acids, 12 flavonoids, 7 coumarins, 10 hydroxycinnamic acids, 1 terpenoid, and 5 lignans. The TPC of SP extracts was higher than that of IBPs extracts in FP and FF. The SP extracts in FP showed better antioxidant activities in vitro compared to those in FF. In addition, polyphenols from CFG fruits protected against H2O2-induced oxidative damage in HepG2 cells, and the protective effect of polyphenols in FP was superior to that in FF. The analysis results showed that CFG fruit has great potential in exploiting natural chemical substances, which can provide valuable pieces of information for the further development and utilization of CFG.
