Drying is an important factor in the formation of green tea flavor. In this study, metabolomic analysis were used to detect characteristic components four teas with clean aroma (CA), chestnut-like (CLA), bean-like (BLA) and high-fired (HFA) produced by adjusting drying temperature. The sensory evaluation results showed that dried at 90°C, 110°C, 140°C 160°C had a aroma, respectively. A total 95 volatile compounds identified. Linalool, naphthalene, 2-methyl-naphthalene, 1-octen-3-ol...
Salicylic acid (SA) is an important plant hormone and signal required for establishing resistance to diverse pathogens diseases. The abundant polyphenols in tea plants also defend from biotic abiotic stresses. However, whether exogenous SA would increase the of adversity relationship between are still poorly understood. Here, we carried out treatment on seedlings performed transcriptome sequencing. inhibited phenylpropanoid flavonoid metabolic pathways but promoted lignin pathways. increased...
Chestnut-like aroma is one of the unique qualities Chinese green tea and has become an important factor influencing consumer decisions. However, chemical formation mechanism chestnut-like during processing remains unclear. In this study, dynamic changes key components contributing to their precursors were analyzed in fresh leaves, fixation first baking tea.The thermal process had effect on volatile causing a significant decrease alcohols esters increase ketones, acids, phenols, sulfur...
This study investigates the volatile compounds of green tea produced with different leaves from spring, summer, and autumn in high-latitude region. A total 95 were identified by gas chromatography-mass spectrometry (GC-MS). Spring, summer contained 68, 72 82 compounds, respectively. Principal component analysis (PCA), partial least squares-discrimination (PLS-DA), hierarchical cluster (HCA) classified samples showed difference. And 32 key characteristic components screened out based on...
Abstract Background The tea plant ( Camellia sinensis (L.) O. Kuntze) is one of the most economically important woody crops. Plastic greenhouse covering cultivation has been widely used in areas northern China. Chlorophyll not only crucial pigment for green tea, but also plays an role growth and development plants. Currently, little known about effect plastic on chlorophyll leaves. Results To investigate leaves, color difference values, contents, gene expression, enzyme activities...
Cuttage is the main propagation method of tea plant cultivars in China. However, some softwood cuttings just form an expanded and loose callus at base, without adventitious root (AR) formation during period. Meanwhile, exogenous auxin could promote AR cuttings, but regulation mechanism has not yet explained clearly. We conducted this study to elucidate regulatory auxin-induced such cuttings. The transcriptional expression profile non-rooting calluses response IBA NAA was analyzed using ONT...
Abstract Benzoates, particularly salicylic acid (SA) and its derivatives, play critical roles in plant immune responses basal defense through hydroxylation glycosylation. Anthracnose is one of the most common devastating diseases tea plants (Camellia sinensis). However, role SA derivatives immunity resistance to anthracnose remains largely unexplored. In present study, we identified characterized a glycosyltransferase, CsUGT74B5, which was significantly downregulated seedlings upon...
This study aimed to clarify the bioavailability mechanism of theaflavins by using Caco-2 monolayer in vitro model. Prior transport theaflavin (TF), theaflavin-3-gallate (TF3G), theaflavin-3'-gallate (TF3'G), and theaflavin-3, 3'-digallate (TFDG), we found cytotoxicity was order TF3'G > TFDG TF3G TF, suggesting galloyl moiety enhances theaflavins. Meantime, made unstable, with stability TF TF3G/TF3'G. Four showed poor Papp values ranging from 0.44 × 10-7 3.64 cm/s absorptive transport. All an...
Shandong matcha has the quality characteristics of bright green color, seaweed-like aroma and strong, fresh brisk taste. In order to identify characteristic components clarify contribution grinding process matcha. Three grades corresponding tencha material were firstly tested with sensory evaluation, volatile extracted headspace solid-phase microextraction (HS-SPME) solvent-assisted flavor evaporation (SAFE) analyzed using GC-MS. The evaluation results showed that high-grade (M-GS) had...
Matcha has a unique aroma of seaweed-like, which is popular with Chinese consumers. In order to effectively understand and use matcha for drinks tea products, we roundly analyzed the variation main quality components 11 samples from different regions in market. Most had lower ratio polyphenols amino acids (RTA), RTA 9 was less than 10, beneficial formation fresh mellow taste matcha. The total volatile compounds concentrations by HS-SPME were 1563.59 ~ 2754.09 mg/L, among terpenoids, esters...
Taxaceae, is a class of dioecious and evergreen plant with substantial economic ecology value. At present many phytochemical analyses have been performed in Taxus plants. And various biological constituents isolated from species. However, the difference compounds antioxidant capacity different tissues T. media not clear.In study, we investigated metabolites activity four media, including bark (TB), fresh leaves (TFL), seeds (TS), aril (TA). In total, 808 compounds, covering 11 subclasses,...
