Kudinoside-D, a triterpenoid saponin derived from Ilex kudingcha suppresses adipogenesis through modulation of the AMPK pathway in 3T3-L1 adipocytes
Fitoterapia 2018 Mar;125:208-216.PMID:29170122DOI:10.1016/j.fitote.2017.11.018.
The leaves of Ilex Kudingcha, locally named "Kudingcha" in China, has been traditionally applied for treating obesity. Studies have demonstrated that the ethanol extract of Ilex kudingcha have anti-adipogenic effects. However, the constituent which was responsible for its anti-obesity and its underlying molecular mechanism has not yet been elucidated. This research explored the anti-obesity effect of kudinoside-D which was a main natural component of triterpenoid saponin from the ethanol extract of Ilex kudingcha, on lipid accumulation and the potential mechanism of action of adipogenesis in 3T3-L1 adipocytes. The adipocytes were treated with various concentrations of Kudinoside D (0 to 40μM) during differentiation. The image-based Oil Red O staining analyses revealed that KD-D, dose dependently reduced cytoplasmic lipid droplet in 3T3-L1 adipocytes with the IC50 is 59.49μM. Meanwhile, major adipogenic transcription factor peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer binding protein-α (C/EBPα) and sterol regulatory element-binding protein 1c (SREBP-1c) were significantly repressed as well as their target genes. The phosphorylation of AMP-activated protein kinase (AMPK) and its downstream target phosphorylated-acetyl CoA carboxylase (ACC) expression were also increased. In addition, the inhibitory effects of KD-D on the expressions of PPARγ and C/EBPα were weakened when cells were cotreated with AMPK inhibitor Compound C. These results indicated KD-D exerts anti-adipogenic effects through modulation of adipogenic transcription factors via AMPK signaling pathway. And the current findings demonstrated that KD-D was a potential therapeutic candidate for alleviating obesity and hyperlipidemia.
Quantitation of kudinoside A, Kudinoside D and kudinoside F in human plasma using a high performance liquid chromatography-electrospray ionization tandem mass spectrometric method
J Chromatogr B Analyt Technol Biomed Life Sci 2014 Dec 1;972:1-5.PMID:25305433DOI:10.1016/j.jchromb.2014.09.023.
A sensitive and selective high performance liquid chromatography-tandem mass spectrometric (HPLC-MS/MS) method for the simultaneous determination of kudinoside A, Kudinoside D and kudinoside F in human plasma has been firstly developed. Samples were prepared after protein precipitation and analyzed on a C18 column interfaced with a triple quadrupole tandem mass spectrometer. Negative electrospray ionization was employed as the ionization source. The mobile phase consisted of acetonitrile-water (35:65) at the flow rate of 0.3mL/min. The analytes and internal standard Ginsenoside Rb1 were both detected by use of multiple reaction monitoring mode. The method was linear in the concentration range of 2.5-1000.0ng/mL. The lower limit of quantification (LLOQ) was 2.5ng/mL. The intra-and inter-day relative standard deviation across three validation runs over the entire concentration range was less than 12.4%. The accuracy determined at three concentrations was within ±4.9% in terms of relative error. The total run time was 7.0min. This assay offers advantages in terms of expediency, and suitability for the analysis of kudinoside A, Kudinoside D and kudinoside F in various biological fluids.
Triterpenoid glycosides from the rhizomes of Allium ascalonicum and their anoctamin-1 inhibitory activity
Nat Prod Res 2021 Nov;35(22):4338-4346.PMID:31965859DOI:10.1080/14786419.2020.1713122.
Ten triterpenoid glycosides including two undescribed compounds (1 and 2) were isolated from the methanol extract of Allium ascalonicum rhizomes. These compounds were structurally elucidated to be 3β-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl-19α-hydroxyolean-12-ene-28-oic acid 28-O-[α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl] ester (1), 3-O-β-D-glucopyranosyl-(1→3)-[α-L-rhamnopyranosyl-(1→2)]-α-L-arabinopyranosyl-3β,19α-dihydroxyoleanane-12-en-28-oic acid (2), lactifoloside C (3), lactifoloside H (4), randiasaponin IV (5), kudinoside G (6), ilexkudinoside W (7), lactifoloside G (8), Kudinoside D (9), and ilexkudinoside T (10) by analyzing their HR-ESI-MS, NMR spectral data and by comparison with those reported in the literature. Compounds 1-10 were evaluated for anoctamin-1 (ANO1) inhibitory activity using yellow fluorescent protein reduction assays. At the concentration of 30 µM, compounds 2 and 9 displayed moderate ANO1 inhibitory percentages of 28.9 ± 0.85% and 26.2 ± 0.65%, respectively.
Quantitative analysis of five kudinosides in the large-leaved Kudingcha and related species from the genus Ilex by UPLC-ELSD
Phytochem Anal 2012 Nov-Dec;23(6):677-83.PMID:22593006DOI:10.1002/pca.2372.
Introduction: The large-leaved Kudingcha from the genus Ilex, which is used as a traditional Chinese tea, contains several characteristic triterpenoid saponins that can be subjected to quality control evaluation. Objective: To develop and validate a rapid method incorporating reverse-phase ultra-performance liquid chromatography coupled with evaporative light scattering detection (UPLC-ELSD) for the simultaneous determination of the five triterpenoid saponins kudinoside L (1), kudinoside C (2), kudinoside A(3), kudinoside F(4) and Kudinoside D(5) in several species of the large-leaved Kudingcha from the genus Ilex and 'Yerba Mate' (Ilex paraguariensis). Methodology: The five compounds were separated using a water-acetonitrile mobile phase with a Waters Acquity BEH C(18)-column (100 × 2.1 mm, 1.7 µm). Results: Separation took 13 min with detection and quantification limits ranging from 12.5 to 29.8 ng and 41.3 to 98.2 ng, respectively. The method was validated according to the regulatory guidelines with respect to precision, stability, repeatability and recovery. The triterpenoid saponins showed a good regression relationship (r(2) > 0.999) within the test ranges, and the recovery of the method was in the 95-105% range. Conclusion: The present method can be used successfully for the quality control of the large-leaved Kudingcha. The different Ilex species showed differences in distribution of the five triterpenoids. Ilex kudingcha, which makes up the major species of the large-leaved Kudingcha, contains the maximum amount of triterpenoid saponins.
Metabolomic Profiles of the Creeping Wood Sorrel Oxalis corniculata in Radioactively Contaminated Fields in Fukushima: Dose-Dependent Changes in Key Metabolites
Life (Basel) 2022 Jan 13;12(1):115.PMID:35054508DOI:10.3390/life12010115.
The biological impacts of the Fukushima nuclear accident, in 2011, on wildlife have been studied in many organisms, including the pale grass blue butterfly and its host plant, the creeping wood sorrel Oxalis corniculata. Here, we performed an LC-MS-based metabolomic analysis on leaves of this plant collected in 2018 from radioactively contaminated and control localities in Fukushima, Miyagi, and Niigata prefectures, Japan. Using 7967 peaks detected by LC-MS analysis, clustering analyses showed that nine Fukushima samples and one Miyagi sample were clustered together, irrespective of radiation dose, while two Fukushima (Iitate) and two Niigata samples were not in this cluster. However, 93 peaks were significantly different (FDR < 0.05) among the three dose-dependent groups based on background, low, and high radiation dose rates. Among them, seven upregulated and 15 downregulated peaks had single annotations, and their peak intensity values were positively and negatively correlated with ground radiation dose rates, respectively. Upregulated peaks were annotated as Kudinoside D (saponin), andrachcinidine (alkaloid), pyridoxal phosphate (stress-related activated vitamin B6), and four microbe-related bioactive compounds, including antibiotics. Additionally, two peaks were singularly annotated and significantly upregulated (K1R1H1; peptide) or downregulated (DHAP(10:0); decanoyl dihydroxyacetone phosphate) most at the low dose rates. Therefore, this plant likely responded to radioactive pollution in Fukushima by upregulating and downregulating key metabolites. Furthermore, plant-associated endophytic microbes may also have responded to pollution, suggesting their contributions to the stress response of the plant.
