The metabolic profiles of Cordyceps bassiana according to fruiting body developmental stage were investigated using gas chromatography-mass spectrometry. We were able to detect 62 metabolites, including 48 metabolites from 70% methanol extracts and 14 metabolites from 100% n-hexane extracts. These metabolites were classified as alcohols, amino acids,(More)
The ameliorating effects of Mango (Mangifera indica L.) flesh and peel samples on plasma ethanol level were investigated using a mouse model. Mango fruit samples remarkably decreased mouse plasma ethanol levels and increased the activities of alcohol dehydrogenase and acetaldehyde dehydrogenase. The (1)H-NMR-based metabolomic technique was employed to(More)
In the model legume Medicago truncatula, Δ1-pyrroline-5-carboxylate synthetase (P5CS), the rate-limiting enzyme of proline biosynthesis, is encoded by three closely related genes, MtP5CS1, MtP5CS2, and MtP5CS3. While MtP5CS1 is constitutively expressed, MtP5CS2 and MtP5CS3 are induced by adverse environmental conditions, of which MtP5CS3 is prevalently(More)
In this study, nuclear magnetic resonance techniques coupled with multivariate data analysis were used for the metabolic profiling of mycelia and fruiting bodies of the entomopathogenic fungi, Cordyceps bassiana according to developmental stages. A direct extraction method using two deuterated solvents of D2O and CDCl3 was used to investigate the relative(More)
Variation of metabolic profiles in Cordyceps pruinosa mycelia cultivated under various media and light conditions was investigated using 1H nuclear magnetic resonance (NMR) analysis and gas chromatography mass spectrometry (GC-MS) with multivariate statistical analysis. A total of 71 metabolites were identified (5 alcohols, 21 amino acids, 15 organic acids,(More)
This study investigated the effects of different temperature conditions on the comprehensive metabolite profiles of Chlorella vulgaris using gas chromatography–mass spectrometry coupled with multivariate statistical analysis. C. vulgaris cells cultivated at 20 °C were transferred to 10 °C incubators at different time points of cultivation [days 0 (TR0D), 7(More)
