L. is a widely cultivated herbal medicinal plant in China and other countries. In this study, two new 2, 3-dihydrobenzofuran glucosides (, ) and fourteen known metabolites (-) were isolated from the stems and leaves of (SLT). The chemical structures of the isolated compounds were characterized comprehensively based on one- and two-dimensional NMR spectroscopy and high resolution mass spectrometry. Absolute configurations of compounds and were determined by ECD calculations. Compounds and exhibited moderate in vitro inhibitory activities against human gastric cancer cell lines (AGS) with IC values of 41.20 μmol/L and 30.43 μmol/L, respectively. The fingerprint profiles of stems and leaves of with three color types of flowers (Janie Yellow Bright, Jinmen Orange, Shouyao Red and Yellow color) were established by high-performance liquid chromatography (HPLC). Ten different batches of stems and leaves were examined as follow: Shouyao Red and Yellow color (1, 2, 3), Janie Yellow Bright (4, 5, 6, 7) and Jinmen Orange (8, 9, 10). Twenty-two common peaks were identified with similarity values ranging from 0.910 to 0.977. Meanwhile, the average peak area of SLT in the three types of flowers was different and it was the highest in Janie Yellow Bright.

Lupins are promising protein crops that accumulate toxic quinolizidine alkaloids (QAs) in the seeds, complicating their end-use. QAs are synthesized in green organs (leaves, stems, and pods) and a subset of them is transported to the seeds during fruit development. The exact sites of biosynthesis and accumulation remain unknown; however, mesophyll cells have been proposed as sources, and epidermal cells as sinks.

Secretory canals are distributed among seed plants, and their diversity is concentrated in many families of angiosperms, while other internal secretory structures such as secretory cavities have been identified only in Rutaceae, Myrtaceae, and Asteraceae. Identifying and recognizing these two types of secretory structures has been complicated, mainly due to their structural similarities. In this study, the ontogeny of canals and secretory cavities in two species of Asteraceae are described and compared, to understand the structural differences between them and allow the establishment of more appropriate homology hypotheses.

The chemical constituents from the stems and leaves of Mycetia hainanensis were isolated by silica gel, ODS gel, and Sephadex LH-20 gel column chromatography and preparative HPLC. The chemical structures of all the isolated compounds were identified on the basis of their physicochemical properties, spectroscopic data, as well as the comparison of their physicochemical and spectroscopic data with the reported data in literature. Twelve compounds were isolated from the 85% ethanol extract of the stems and leaves of M.

Nanoselenium shows potential trends in improving plant health and food quality. In this study, different concentrations of nanoselenium were sprayed on the leaves of alfalfa. Compared to the control, nanoselenium (100 mg·L) significantly increased SeMet and SeMeCys contents in the roots, stems, and leaves of alfalfa.
