Metabolite profile, antioxidant and antinociceptive activities of  bark and leaf methanolic extracts were investigated. By means of HPLC-DAD-ESI-TOF and HPLC-DAD-ESI-MS/MS, a total of 33 phenolics were identified, including 15 secoiridoids, 6 phenylpropanoids, 3 flavonoids, 3 lignans and 6 low molecular weight phenols. Validated quantitative analysis show that syringin (2.52%) and rutin (1.13%) are the main phenolic compounds in bark and leaf, respectively. Notable radical scavenging and antinociceptive activities of the bark and leaf extracts were confirmed by DPPH and ABTS assays and by hot-plate method in mice, respectively. Our results could lay the scientific basic of future clinical perspectives of lilac bark and leaf.

Background: Acquiring representative bacterial 16S rRNA gene community profiles in plant microbiome studies can be challenging due to the excessive co-amplification of host chloroplast and mitochondrial rRNA gene sequences that reduce counts of plant-associated bacterial sequences. Peptide Nucleic Acid (PNA) clamps prevent this by blocking PCR primer binding or binding within the amplified region of non-target DNA to stop the function of DNA polymerase. Here, we applied a universal chloroplast (p)PNA clamp and a newly designed mitochondria (m)PNA clamp to minimise host chloroplast and mitochondria amplification in 16S rRNA gene amplicon profiles of leaf, bark and root tissue of two oak species (Quercus robur and Q.

In Situ Analysis of Plant Tissue Using Arc iKnife Ionization Mass Spectrometry.

Anal Chem

January 2025

Cigar Technology Innovation Center of China Tobacco, Cigar Fermentation Technology Key Laboratory of China Tobacco (China Tobacco Sichuan Industrial Co., Ltd.), Chengdu 610066, People's Republic of China.

This study developed a portable arc iKnife ionization mass spectrometry (AII-MS) technique integrating a surgical knife with low-temperature arc plasma to interact with plant tissues. The thermal energy from the arc plasma induces the sputtering of water-containing plant tissues, leading to the formation of aerosols. These aerosols are then charged by plasma-generated ions, producing charged microdroplets that are ultimately detected by a mass spectrometer.

Water storage capacity and capacitance in trees regulate hydration levels, providing water reserves during drought. However, the effects of varying traits, tissue fractions and of different water pools on the allometry of branch-/sample-level properties have not been systematically investigated. We analyse the relationships between branch size and branch capacity and capacitance with respect to wood density, xylem vulnerability to embolism, and tissue fractions.

Enhancing Acclimatization Conditions for 'Fire': A Comparative Analysis of Substrate Effects on Growth and Survival.

Plants (Basel)

January 2025

Department of Floriculture and Dendrology, Institute of Landscape Architecture, Urban Planning and Garden Art, Hungarian University of Agriculture and Life Sciences (MATE), Villányi Street 29-43, 1118 Budapest, Hungary.

This study investigates the acclimatization success of 'Fire', a popular ornamental bromeliad, through in vitro propagation on various substrates. Due to the increasing demand for , micropropagation offers a promising solution to overcome the limitations of traditional propagation methods. In this research, acclimatization was conducted in two trial types: in the one-step greenhouse conditions, and in two-step acclimatization, which introduced a controlled laboratory step before transferring plants to the greenhouse.
