Introduction: Decarboxylation is an important step for efficient production of the major active components in cannabis, example, Δ9-tetrahydrocannabinol (Δ9-THC), cannabidiol (CBD), and cannabigerol (CBG). These cannabinoids do not occur significant concentrations cannabis but can be formed by decarboxylation their corresponding acids, predominant plant. Study kinetics importance phytocannabinoid isolation dosage formulation medical use. Efficient analytical methods are essential...
The most common ways of assessing adherence to oral antipsychotic medications in research and clinical practice are self-report physician report. This prospective study examined the agreement among measures 52 outpatients with schizophrenia.Participants were assessed at baseline during a visit their outpatient clinic followed for 12 weeks. Adherence was by using subjective (self-report report) objective (pill counts conducted home, electronic monitoring, blood plasma concentrations)....
The homeodomain leucine zipper (HD-Zip) genes encode transcription factors that have diverse functions in plant development and often been implicated stress adaptation. HD-Zip are the most abundant group of homeobox (HB) plants do not occur other eukaryotes. This paper describes complete annotation families I, II III from rice compares these gene with Arabidopsis a phylogeny reconstruction. Orthologous pairs were predicted based on neighbour joining maximum parsimony (MP) trees support...
Tuberaceae is one of the most diverse lineages symbiotic truffle-forming fungi. To understand molecular underpinning ectomycorrhizal truffle lifestyle, we compared genomes Piedmont white (Tuber magnatum), Périgord black melanosporum), Burgundy aestivum), pig (Choiromyces venosus) and desert (Terfezia boudieri) to saprotrophic Pezizomycetes. Reconstructed gene duplication/loss histories along a time-calibrated phylogeny Ascomycetes revealed that Tuberaceae-specific traits may be related...
Abstract Terpenes are the major components of essential oils present in various Cannabis sativa L. varieties. These compounds responsible for distinctive aromas and flavors. Besides quantification cannabinoids, determination terpenes C. strains could be importance plant selection process. At University Mississippi, a GC-MS method has been developed validated cannabis material, viz., α-pinene, β-pinene, β-myrcene, limonene, terpinolene, linalool, α-terpineol, β-caryophyllene, α-humulene,...
In this article, we report on complex nanochemistry and transport phenomena associated with silver nanocrystal formation by electron beam induced growth liquid cell microscopy (LCEM). We synthesized nanocrystals using scanning transmission (STEM) synthesis systematically varied the dose rate, a parameter thought to regulate kinetics via rate of metal precursor reduction. Rationally modifying solution chemistry tert-butanol scavenge radical oxidizing species established strongly reducing...
The genus Arthrinium includes important plant pathogens, endophytes and saprobes with a wide host range geographic distribution. In this paper, 74 strains isolated from various substrates such as bamboo leaves, tea plants, soil air karst caves in China were examined using multi-locus phylogeny based on combined dataset of ITS rDNA, TEF1 TUB2, conjunction morphological characters, association ecological Eight new species described their distinct phylogenetic relationships characters. Our...
Formation kinetics of metal nanoparticles are generally described via mass transport and thermodynamics‐based models, such as diffusion‐limited growth classical nucleation theory (CNT). However, monomers commonly assumed precursors, leaving the identity molecular intermediates their contribution to nanoparticle formation unclear. Herein, liquid phase transmission electron microscopy (LPTEM) reaction kinetic modeling utilized establish mechanisms discover during silver formation. Quantitative...
In natural product chemistry, it is often crucial to determine sugar composition as well the absolute configuration of each monosaccharide in glycosides. An ultra-performance liquid chromatography method using both photodiode array (PDA) and mass spectrometry detectors (UPLC-UV/MS) was developed for qualitative analysis enantiomers. Within a single injection, 16 derivatives including 6 pairs aldose enantiomers (<sc>D</sc>/<sc>L</sc>-glucose, <sc>D</sc>/<sc>L</sc>-galactose,...
Six new octulosonic acid derivatives (1–6) were isolated from the flower heads of Roman chamomile (Chamaemelum nobile). Their structures elucidated by means spectroscopic interpretation. The biological activity compounds was evaluated toward multiple targets related to inflammation and metabolic disorder such as NAG-1, NF-κB, iNOS, ROS, PPARα, PPARγ, LXR. Similar action NSAIDs, all six increased NAG-1 2–3-fold. They also decreased cellular oxidative stress inhibiting ROS generation....
Leaves of the Southeast Asian plant Mitragyna speciosa are used to suppress pain and mitigate opioid withdrawal syndromes. The potential threat abuse ready availability this uncontrolled psychoactive have led need for improved analytical techniques detection major active components, mitragynine 7-hydroxymitragynine. Three independent chromatographic methods coupled two systems, GC with MS, supercritical fluid chromatography diode array detection, HPLC MS were compared analysis other indole...
This paper provides a comparative account of the essential oil chemical composition and biological activities five Brazilian species Baccharis (Asteraceae), namely B. microdonta, pauciflosculosa, punctulata, reticularioides, sphenophylla. The compositions three (B. sphenophylla) are reported for first time. Analyses by GC/MS showed notable differences in species. α-Pinene was observed highest concentration (24.50%) reticularioides. Other major compounds included α-bisabolol (23.63%)...
Genome sequencing has been widely used in plant research to construct reference genomes and provide evolutionary insights. However, few species have had their whole genome sequenced, thus restraining the utility of these data. We collected 1,093 samples vascular growing Ruili Botanical Garden, located southwest China. Of these, we sequenced 761 voucher specimens stored Herbarium China National GeneBank.
Avocado oil is prized for its high nutritional value due to the substantial amounts of triglycerides (TGs) and unsaturated fatty acids (FAs) present. While avocado traditionally extracted from mature fruit flesh, alternative sources such as seed have recently increased in popularity. Unfortunately, sufficient evidence not available support claimed health benefit safe use oils. To address potential quality issues identify possible adulteration, authenticated oils peel, pulp by supercritical...
