Thermal Control Using Far-Infrared Irradiation for Producing Deglycosylated Bioactive Compounds from Korean Ginseng Leaves
Molecules 2022 Jul 26;27(15):4782.PMID:35897960DOI:10.3390/molecules27154782.
Although ginseng leaf is a good source of health-beneficial phytochemicals, such as polyphenols and ginsenosides, few studies have focused on the variation in compounds and bioactivities during leaf thermal processing. The efficiency of far-infrared irradiation (FIR) between 160 °C and 200 °C on the deglycosylation of bioactive compounds in ginseng leaves was analyzed. FIR treatment significantly increased the total polyphenol content (TPC) and kaempferol production from Panasenoside conversion. The highest content or conversion ratio was observed at 180 °C (FIR-180). Major ginsenoside contents gradually decreased as the FIR temperature increased, while minor ginsenoside contents significantly increased. FIR exhibited high efficiency to produce dehydrated minor ginsenosides, of which F4, Rg6, Rh4, Rk3, Rk1, and Rg5 increased to their highest levels at FIR-190, by 278-, 149-, 176-, 275-, 64-, and 81-fold, respectively. Moreover, significantly increased antioxidant activities were also observed in FIR-treated leaves, particularly FIR-180, mainly due to the breakage of phenolic polymers to release antioxidants. These results suggest that FIR treatment is a rapid and efficient processing method for producing various health-beneficial bioactive compounds from ginseng leaves. After 30 min of treatment without leaf burning, FIR-190 was the optimum temperature for producing minor ginsenosides, whereas FIR-180 was the optimum temperature for producing polyphenols and kaempferol. In addition, the results suggested that the antioxidant benefits of ginseng leaves are mainly due to polyphenols rather than ginsenosides.
Identification of Specific Glycosyltransferases Involved in Flavonol Glucoside Biosynthesis in Ginseng Using Integrative Metabolite Profiles, DIA Proteomics, and Phylogenetic Analysis
J Agric Food Chem 2021 Feb 10;69(5):1714-1726.PMID:33512142DOI:10.1021/acs.jafc.0c06989.
Ginseng contains a variety of flavonol glycosides that possess diverse biological activities; however, scant information of flavonoid glycosylation was reported in ginseng. We found that Panasenoside and kaempferol 3-O-glucoside were commonly accumulated along with cultivation years in leaves. In order to explore the procedure of flavonol glycosylation in ginseng, 50 UDP-glycosyltransferases (UGTs) were screened out using differentiated data-independent acquisition (DIA) proteomics and phylogenetic analysis. UGT92A10 and UGT94Q4 were found contributing to the formation of kaempferol 3-O-glucoside. UGT73A18, UGT74T4, and UGT75W1 could catalyze galactosylation of kaempferol 3-O-glucoside. Ser278, Trp335, Gln338, and Val339 were found forming hydrogen bonds with UDP-galactose in UGT75W1 by docking. MeJA induced transcripts of UGT73A18 and UGT74T4 by over fourfold, consistent with the decrease of kaempferol 3-O-glucoside, which indicated that these genes may be related to resisting adversity stress in ginseng. These results highlight the significance of integrative metabolite profiles, proteomics, and phylogenetic analysis for exploring flavonol glycosylation in ginseng.
A novel acylated quercetin glycoside and compounds of inhibitory effects on α-glucosidase from Panax ginseng flower buds
Nat Prod Res 2020 Sep;34(18):2559-2565.PMID:30450965DOI:10.1080/14786419.2018.1543685.
A novel acylated quercetin glycoside, floralpanasenoside A (1) and five known flavonoid glycosides, Panasenoside (2), quercetin 3-O-(2''-β-D-glucopyranosyl)-β-D- galactopyranoside (3), trifolin (4) kaempferol 7-O-α-L-rhamnoside (5), and afzelin (6) were isolated from the flower buds of Panax ginseng. Their structures were established by spectroscopic data and comparison with the literature values. Four of the six isolated compounds including 1 (IC50 = 62.4) exhibited α-glucosidase inhibitory activity with IC50 values lower than acarbose (385.2 μM). The molecular docking study indicated that 1 bound to the active site of α-glucosidase with numerous hydrogen bond interactions.
Identification of key metabolites based on non-targeted metabolomics and chemometrics analyses provides insights into bitterness in Kucha [Camellia kucha (Chang et Wang) Chang]
Food Res Int 2020 Dec;138(Pt B):109789.PMID:33288175DOI:10.1016/j.foodres.2020.109789.
Camellia kucha (Chang et Wang) Chang is a special tea in China, which is extremely bitter but beneficial for human health. However, there are no systematic studies on Kucha metabolites, especially those associated with bitterness. In this study, a non-targeted metabolomics approach based on UHPLC-LTQ-Orbitrap-MS was applied to comprehensively profile the characteristic metabolites of two Kucha cultivars by comparison with three common tea cultivars. A total of 90 differential metabolites were identified. Among them, eight key metabolites (theacrine, 2,4-dimethyl-1H-indole, EGCG, dihydrokaempferol, Panasenoside, 3-cresotinic acid, 3-methylglutaconic acid, and L-histidine) were more abundant in Kucha than in the controls, most of which were positively correlated with bitterness. Furthermore, quantitative analysis of some important catechins and alkaloids by HPLC implied absolutely higher concentrations of EGCG and theacrine in Kucha, which was similar to the metabolomics results. These results will be contribute to future research on the bitter and nutritional properties of Kucha.
Rapid method for simultaneous determination of flavonoid, saponins and polyacetylenes in folium ginseng and radix ginseng by pressurized liquid extraction and high-performance liquid chromatography coupled with diode array detection and mass spectrometry
J Chromatogr A 2009 May 1;1216(18):3825-30.PMID:19272605DOI:10.1016/j.chroma.2009.02.065.
A rapid pressurized liquid extraction (PLE) and high-performance liquid chromatography coupled with diode array detection and mass spectrometry (HPLC-DAD-MS) method for the simultaneous determination of one flavonoid (Panasenoside), nine saponins (ginsenoside Rg1, Re, Rf, Rg2, Rb1, Rc, Rb2, Rb3 and Rd) and two polyacetylenes (panaxydol and panaxynol) in folium ginseng and radix ginseng was developed. A Prevail C(18) rocket column (33 mm x 7 mm, 3.0 microm) and gradient elution were used during the analysis. Flavonoid was quantified at 355 nm, and saponins and polyacetylenes were determined at 203 nm. The chromatographic peaks of 12 investigated compounds in samples were unambiguously identified by compared their UV spectra and/or MS data with the related reference compounds. All calibration curves showed good linearity (r>0.999) within the test ranges. The intra- and inter-day variations for 12 analytes were less than 1.17% and 2.17%, respectively. The developed method was successfully applied to determine the investigated compounds in 10 samples of radix ginseng and folium ginseng, respectively. The result showed that PLE combined with rocket column HPLC analysis could provide a rapid method for analysis of compounds in traditional Chinese medicines (TCMs), which is helpful to comprehensive evaluation of quality of radix ginseng and folium ginseng.
