Summary: Nitrogen supply affects the morphological traits, N use efficiency, photosynthetic capacity, and saponins accumulation in Panax notoginseng. Increasing N supply reduces root biomass, enhances above-ground biomass, and increases N content. High N supply reduces NUE, NC, and Pn, while increasing SLN, Chl, and NL. Root biomass is positively correlated with NUE, yield, and Pn, while above-ground biomass is negatively correlated with PNUE. Saponins content is positively correlated with NUE and Pn. Overall, excess N reduces root and carbon-containing secondary metabolites (active ingredient) yield in P. notoginseng.

Summary: The optimal light intensity for saponin accumulation in roots of medicinal plants and the correlation of light-driven biosynthesis of triterpene saponins with gene expression levels remain unclear. However, it was found in this study that under moderate light conditions (about 10% full sunlight), there was a significant increase in total saponin content in three-year-old Panax notoginseng plants, which could be attributed to the expression levels of DS and CYP716A47 genes.

Summary: This study investigated the regulatory mechanism of Panax notoginseng saponins (PNS) biosynthesis. Upstream promoters of PnSS and PnSE were cloned and analyzed, and their response to exogenous GA and ABA signals was verified. PnCOX11 and PnDCD, binding proteins that respond to peripheral hormones, were identified and their interaction with the promoters was confirmed. The structural analysis, subcellular localization, and expression of the recombinant proteins were also examined. This study provides fundamental information for the investigation of the transcription regulatory mechanism of PNS biosynthesis.

Summary: Panax notoginseng, also known as Burki, is a well-known traditional Chinese medicine with a long history of medicinal use. Studies have shown that it can alleviate mitochondrial damage caused by amyloid beta protein and protect cell viability by regulating autophagy. This mechanism may involve enhancing autophagy without depending on the PINK1 gene.

Summary: Panax Notoginseng saponins (PNS), the extract of Panax notoginseng, exerts cardioprotective effects in acute myocardial infarction by inducing cardiomyocyte autophagy, inhibiting platelet aggregation, enhancing endothelial cell migration and angiogenesis. PNS and its main constituents Rg1 and Rd also directly inhibit platelet aggregation in healthy subjects and enhance glucose deprivation-induced autophagy in cardiomyocytes. These findings provide insights for drug development from natural products against ischemic heart diseases and heart failure post myocardial infarction.

Summary: Three undescribed dammarane-type triterpene saponins were isolated from the roots of Panax notoginseng, along with seventeen known ones. The chemical structures of the new compounds were determined using HR-MS, NMR, and chemical methods. Compound 1, a fucose-containing triterpene saponin, was reported for the first time in the genus Panax. In addition, the isolated compounds were evaluated for their in vitro neuroprotective effects, and compounds 11-12 showed significant protective effects against 6-hydroxydopamine-induced PC12 cell injury.

Summary: This study identified and characterized the interaction between PnMYB2 and key enzymes in Panax notoginseng. The study also confirmed the interaction between PnMYB2 and the upstream sequences of PnSS and PnSE1 promoters. The full-length cDNA sequence of PnMYB2 was isolated and its structure and phylogenetic analysis were conducted. The study showed that PnMYB2 is localized in the nucleus and can specifically bind to certain elements. This research provides a theoretical basis for the transcriptional regulation of saponin biosynthesis in Panax notoginseng.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
