The traditional medicine Ginseng mainly including Panax ginseng and quinquefolius is the most widely consumed herbal product in world. Despite extensive investigation of biosynthetic pathway active compounds ginsenosides, our current understanding metabolic interlink between ginsenosides synthesis primary metabolism at whole-plant level. In this study, tissue-specific profiling secondary metabolites two different species were investigated by gas chromatography- liquid chromatography coupled...
This work aims at identifying the effects of ethylene on response Arabidopsis thaliana root system to cadmium chloride (CdCl2) stress. Two ethylene-insensitive mutants, ein2-5 and ein3-1eil1-1, were subjected (25, 50, 75, 100 μM ) CdCl2 concentrations, from which 75 concentration decreased growth by 40% compared with wild type Col-0 as a control. Ethylene biosynthesis increased in treatment. The length primary tip ein3-1eil1-1 after treatment, suggesting that play role Cd superoxide roots...
Salinity is the main environmental factor responsible for limited plant growth in many areas of world. Gleditsia sinensis Lam. a shelter forest tree species that does not require high-quality soil and can even grow mild saline soil. This study mainly explored tolerance G. to salt effect exogenous calcium addition on salinized The concentrations NaCl were set as 0 mmol/L, 100 200 mmol/L. Compared with control, under treatment it was observed leaves turned yellow, electrical conductivity...
: Ultraviolet-B (UV-B) radiation (280-320 nm) may induce photobiological stress in plants, activate the plant defense system, and changes of metabolites. In our previous work, we found that between two Astragalus varieties prescribed by Chinese Pharmacopoeia, mongholicus has better tolerance to UV-B. Thus, it is necessary study metabolic strategy under UV-B further. present study, used untargeted gas chromatography-mass spectrometry (GC-MS) targeted liquid (LC-MS techniques) investigate...
Ginsenosides, the major compounds present in ginseng, are known to have numerous physiological and pharmacological effects. The processes, enzymes genes involved ginsenoside synthesis P. ginseng been well characterized. However, relatively little information is about dynamic metabolic changes that occur during accumulation ginseng. To explore this topic, we isolated metabolites from different tissues at growth stages, identified characterized them by using gas chromatography coupled with...
The medicinal plant Catharanthus roseus accumulates large numbers of terpenoid indole alkaloids (TIAs), including the pharmaceutically important vinblastine, vincristine, ajmalicine, and serpentine. phytohormone ethylene or methyl jasmonate (MeJA) can markedly enhance alkaloid accumulation. interaction between MeJA in regulation TIA biosynthesis C. is unknown. Here, a metabolomics platform reported that based on liquid chromatography (LC) coupled with time-of-flight mass spectrometry to...
In this work, the changes in isoflavone levels and expression of genes involved their biosynthesis were studied two Astragalus by UPLC-MS real-time PCR after 10 days UV-B treatment (λmax = 313 nm, 804 J m-2 ). Isoflavones significantly induced irradiation. The influence might be activated regulation these target genes. Our results indicate that (1) resistance membranaceus not as good mongholicus enhanced radiation environment; (2) accumulation calycosin calycosin-7-glucoside with roots A....

Salvia miltiorrhiza is a well-known traditional Chinese medicine (TCM) for its bioactive tanshinones that are used to treat various diseases and have high antimicrobial properties. Previous studies shown tanshinone accumulation in S. was be significantly induced by fungal elicitors. Mitogen-activated protein kinases (MAPKs), which play critical roles plant–microbe interactions cellular processes, known regulate the of metabolites. In this study, we aimed identify MAPK families screen SmMAPKs...
Astragalus membranaceus Bge. var. mongholicus (Bge.) Hsiao (A. mongholicus, family Leguminosae) is one of the most important traditional Chinese herbs because it contains lots bioactive metabolites, which have beneficial and pharmacological effects on health. Simultaneously, has been proved to be a salt-tolerant plant-one potential species control soil salinization. Therefore, sensitive specific ultra-pressure liquid chromatography coupled with tandem mass spectrometric (UPLC-MS/MS) method...
Tilia amurensis Rupr. is a crucial species widely used in our life, because its wood easy to process due low specific gravity and good elasticity. To understand the effect of latitudinal gradients on T. metabolites profiles, we collected data from six different latitudes about physiological indicators such as temperature, light, precipitation, then analyzed differences metabolite profiles these latitudes. The metabolomes (SFS 49°28′53.26″ N, WY 48°06′51.314″ LS 47°11′1.71″ BL 45°7′55″ BH...
Suaeda glauca and Puccinellia tenuiflora are two important saline-alkali tolerant plants that can improve the soil properties. For exploring different tolerance mechanisms between them, GC-MS-based metabolomics was used to comprehensively evaluate primary metabolites differences, a total of 51 were present in quantities. The identified compounds mainly 11 sugars, 7 amino acids, 5 alcohols 18 organic acids; they play an role responding stress distinguish S. P. tenuiflora. All classes showed...
Phosphorus (P) deficiency affects plant yield and quality, yet at the same time, excessive phosphorus application does not necessarily promote growth of plants. How to maintain a balance between biomass accumulation is problem. Therefore, purpose this research was explore relationship quality Bupleurum fertilization, based on three fertilization levels (20 kg∙ha-1; 10 0 kg∙ha-1). We adopted gas chromatography-mass spectrometry assess response primary metabolites different tissues (flowers,...
Abstract Background Salvia L. (Lamiaceae) found in almost all countries temperate and tropical regions. Both S. aegyptiaca lanigera Poir. have a rather wide distribution Egypt (Mediterranean region, Gebel Elba nearly the whole Sinai). species showed antibacterial antifungal activities against several groups of food microorganisms pathogens, so they are considered as natural foods preservatives. Aim Investigate phytochemical profiles & collected from their habitats test antimicrobial both...

In this study, we examined Vicia seeds using gas chromatography-mass spectrometry (GC-MS). The metabolic differences of twelve species were assessed. 184 metabolites identified. classified via multivariate data analyses into four clusters. V. unijuga was most enriched in fatty acids and anthraquinones contents while highest levels amino acids, alcohols phenolic costata. Clustering analysis biochemical profiles matched with the pervious phenotypic observation all from section Cracca grouped...
Bupleurum (Apiaceae) is widely used in traditional Chinese medicine to treat inflammatory and infectious diseases. Although roots are the only parts China, other countries use whole plant. The yield quality of depend mainly on fertilizers, especially nitrogen. current study aimed assess relationship between nitrogen fertilization level metabolomic response different (flowers, main shoots, lateral shoots roots) three levels (control group: 0 kg·ha−1; low-nitrogen 55 high-nitrogen 110...
