“…Te review of research studies revealed the generation of silver nanoparticles within the polymer network utilizing plant extract, notwithstanding biocompatible cellulose silver nanocomposites for antimicrobial, fabric, and therapeutic applications [7][8][9]. Te Xenostegia tridentata (L.) possesses good diuretic, antiallergic, bitter, astringent, calefacient, laxative, purgative, fever, snake bite, tonic, and spasmolytic characteristics [10,11]. Xenostegia tridentata (L.) leaf has been found to contain 3,5-cafeoylquinic acid, quercetin-3-o-rhamnoside, kaempferol-3-o-rhamnoside, luteolin-7-o-glucoside, β-sterol, and stigma sterol compounds that can be capping and reducing agents (XTLLs) which can easily reduce the silver nitrate solution to Ag ions in cellulose matrix [12][13][14].…”

A novel green synthesis of cellulose/Ag nanocomposites (Cell/XTLL Ag NCs) with in situ generated silver nanoparticles using Xenostegia tridentata (L.) leaf extracts (XTLL). The synthesized nanocomposites have been appreciably characterized by SEM, TEM, FT-IR, XRD, UV-Vis spectrometer, AFM, DRS, XPS, TGA, and ICP-OES. The Ag nanoparticles found for the Cell/XTLL 60 mM AgNO3 have an average particle size of 33.78 nm. Moreover, Cell/XTLL Ag NC film, prepared with 60 mM AgNO3, suggests greater antioxidant activity. The most potent cell/XTLL 60 mM AgNO3 against Escherichia coli, Staphylococcus aureus, Trichoderma viride, and Fusarium oxysporum has strong antimicrobial activity and the best antimicrobial properties due to the fact that because the concentration of AgNO3 solution increased, the zone of inhibition additionally accelerated. The Cell/XTLL 60 mM becomes examined in vitro for its ability of human tumor cell growth inhibitory impact on human breast cancer cell line MCF-7 using MTT assay. The catalytic activity of Cell/XTLL 60 mM AgNO3 was assessed by the photocatalytic degradation of methylene blue and compared with bare cellulose. The Ag NPs are homogeneously unfolded out in Cell/XTLL 60 mM AgNO3 which leads to low electron-hole recombination and accelerated dye adsorption. In particular, 100 mg of Cell/XTLL 60 mM AgNO3, as catalyst, showed excellent photocatalytic activity with the efficiency of 91% degradation of methylene blue (MB).

Combining multiple lines of evidence to elucidate the origin and introduction pathway of bitou bush (Chrysanthemoides monilifera subsp. rotundata) in Australia

Understanding the historical context of biological invasions can improve weed management outcomes. In this study, we aim to identify the introduction pathway of bitou bush (Chrysanthemoides monilifera subsp. rotundata) into Australia and its biogeographical origin in southern Africa by combining multiple lines of evidence from genomic tools and historical documentation. Geographic structure of genomic diversity based on SNPs supported the previous analysis of the invasion pathway of bitou bush between the two countries and within Australia, namely that all Australian material originated from the southern part of the South African distribution. Our synthesis of historical records points to the introduction of this plant into eastern Australia in Newcastle, New South Wales, from its native range in South Africa, via dry shipping ballast in about 1900. Variation in the chloroplast genome was also informative as to the biogeographical origin of Australian material and the context of the introduction. Ten unique haplotypes were discovered in South Africa with only one occurring throughout Australia, indicating an introduction from a single source population to eastern Australia. The matching haplotype was from East London, a port in South Africa with documented shipping connections to Newcastle in eastern Australia, where the weed was first recorded. Historical records suggest that the most plausible explanation for the origins of the isolated bitou bush population in Western Australia is via the shipping of steel billets or landscape plantings associated with shipping companies. The most likely introduction pathway linked the eastern Australian steel processing ports of Newcastle or Port Kembla to the Western Australian port of Kwinana in 1995. Discovering the origin and pathway of bitou bush invasions in Australia opens new opportunities for sourcing biological control agents with a higher chance of impact as well as identifying additional quarantine measures to improve outcomes and reduce long-term costs to management.

LC-MS/MS metabolomics-facilitated identification of the active compounds responsible for anti-allergic activity of the ethanol extract of Xenostegia tridentata

In vivo and in vitro anti-allergic activities of ethanol extract of Xenostegia tridentata (L.) D.F. Austin & Staples were investigated using passive cutaneous anaphylaxis reaction assay and RBL-2H3 cell degranulation assay, respectively. The crude ethanol extract exhibited promising activities when compared with the known anti-allergic agents, namely dexamethasone and ketotifen fumarate. The ethyl acetate subfraction showed the highest anti-allergic activity among various sub-partitions and showed better activity than the crude extract, consistent with the high abundance of total phenolic and flavonoid contents in this subfraction. LC-MS/MS metabolomics analysis and bioassay-guided isolation were then used to identify chemical constituents responsible for the anti-allergic activity. The results showed that major components of the ethyl acetate subfraction consist of 3,5-dicaffeoylquinic acid, quercetin-3-O-rhamnoside, kaempferol-3-O-rhamnoside and luteolin-7-O-glucoside. The inhibitory activity of the isolated compounds against mast cell degranulation was validated, ensuring their important roles in the anti-allergic activity of the plant. Notably, besides showing the anti-allergic activity of X. tridentata, this work highlights the role of metabolomic analysis in identifying and selectively isolating active metabolites from plants.
