JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024. [PMID: 39230063 DOI: 10.1002/jsfa.13860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Revised: 07/24/2024] [Accepted: 07/30/2024] [Indexed: 09/05/2024]
Abstract
BACKGROUND Michelia macclurei Dandy is a traditional Chinese medicinal plant, but little is understood about the bioactive compositions and biological potential of its different parts, limiting their applications. This study aims to identify the bioactive compositions and analyze differences in accumulation patterns from different parts of Michelia macclurei (heartwood, sapwood, bark, root, leaf, and fruit) using metabolomics. It also seeks to explore their biological potential and analyze the relationship between the bioactive compositions and biological potential. RESULTS A total of 63 volatile metabolites (VMs) were identified by gas chromatography-mass spectrometry (GC-MS) in six parts, and the VMs in each part were dominated by sesquiterpenes and their derivatives (71.40-88.32%). Six parts of Michelia macclurei contained structurally diverse non-volatile metabolites (NVMs) with a total of 207 bioactive compounds, including 92 alkaloids, 30 flavonoids, 19 lignans, and 18 organic acids, utilizing ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) analysis. Multivariate statistical analysis showed that the accumulation patterns of bioactive compositions differed significantly among the different parts, and the 25 VMs and 72 NVMs could be considered potential markers for distinguishing the different parts of Michelia macclurei. The excellent antioxidant and enzyme inhibitory capacity of extracts of all six parts was indicated by in vitro bioactivity assays. Pearson's correlation analysis showed that the bioactive compositions in the six parts were significantly correlated with antioxidant and enzyme inhibitory activities. CONCLUSION This study offers helpful information on the distribution of bioactive compositions in different parts of Michelia macclurei and confirms the excellent antioxidant, and enzyme inhibitory potential of its extracts, which could provide scientific evidence for its potential applications in the pharmaceutical industry, cosmetics, and functional foods. © 2024 Society of Chemical Industry.

Hyeon H, Jang EB, Kim SC, Yoon SA, Go B, Lee JD, Hyun HB, Ham YM. Metabolomics Reveals Rubiadin Accumulation and the Effects of Methyl Jasmonate Elicitation in Damnacanthus major Calli. PLANTS (BASEL, SWITZERLAND) 2024; 13:167. [PMID: 38256721 PMCID: PMC10820265 DOI: 10.3390/plants13020167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 12/26/2023] [Accepted: 01/06/2024] [Indexed: 01/24/2024]
Abstract
Callus suspension techniques have been considered attractive for improving bioactive metabolite productivity; methyl jasmonate (MeJA) is a widely used elicitor for stimulating synthetic pathways. In this study, a multivariate analysis-based metabolomics approach was employed to investigate the primary and specialized metabolites in the leaves, unelicited calli, and 100 or 200 μM MeJA elicited calli of Damnacanthus major. Rubiadin, a powerful anthraquinone with various therapeutic properties, was only identified in D. major calli, accumulating in a MeJA elicitation concentration-dependent manner. Callus cultures also contained high levels of amino acids, sugars, and phenolic compounds, indicating energy metabolism and metabolic adaptation responses for proliferation and stabilization. Regarding MeJA application, elicited calli contained higher amounts of quinic acid, kaempferol, and glucose with lower amounts of sucrose and raffinose than those in the unelicited control, which were closely related to protective mechanisms against MeJA. Moreover, excessive elicitation increased the asparagine, fructose, and raffinose levels and decreased the glucose and sucrose levels, which was ascribed to increased activation of the aminoacyl-tRNA biosynthesis pathway and wider utilization of glucose than of fructose after sucrose degradation. These results will be useful for optimizing plant cell culture techniques to achieve high production rates for valuable specialized metabolites.

'Lennei' and Their Detailed Qualitative and Quantitative Profiling. Molecules 2023; 28:6335. [PMID: 37687163 PMCID: PMC10488917 DOI: 10.3390/molecules28176335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 08/22/2023] [Accepted: 08/28/2023] [Indexed: 09/10/2023] Open
Abstract
A response surface methodology (RSM) with a central composite design (CCD) was developed to predict and apply the best ultrasound-assisted extraction (UAE) conditions, including the extraction time, the composition of aqueous-ethanolic extractants, and the solvent-to-plant-material ratio, for obtaining the highest yields of different types of polyphenolic components from the dried flower buds of Magnolia × soulangeana Soul.-Bod. var. 'Lennei' (MSL). The novel approach in the RSM procedure resulted from the simultaneous optimisation of UAE conditions to obtain extracts with the highest antioxidant and antiradical potential (examined as dependent variables), using appropriate spectrophotometric assays, with Folin-Ciocâlteu and 2,2-diphenyl-1-picrylhydrazyl reagents, respectively. The use of 66.8% (V/V) ethanol as the extraction solvent during the 55.2 min extraction protocol and the ratio of extractant volume to herbal substance of 46.8 mL/g gave the highest total yield of bioactive antioxidant phenolics in the extract obtained. For this herbal preparation, a qualitative and quantitative analysis was performed using combined chromatographic (LC), spectroscopic (PDA), and tandem mass spectrometric (ESI-QToF-MS/MS) techniques. A detailed phytochemical profiling, conducted for the first time, documented substantial amounts of various polyphenolic antioxidants, especially phenylethanoids and flavonoids, in the MSL flower buds. Their average total content exceeded 30.3 and 36.5 mg/g dry weight, respectively.
