ABSTRACT Introduction In China, Typhae Pollen (TP) has been extensively utilized as a medicinal product, which is the dried pollen from male inflorescences of Typha angustifolia L. (TA), orientalis Presl (TO), or species within same genus. However, existing methods for differentiating botanical origin and controlling quality TP are confusing, unreliable, unsystematic. Objectives This study aims to elucidate microstructural similarities differences between grains two develop comprehensive method qualitative quantitative analysis multiple flavonoids phenolic acids in TP. Methodology Scanning electron microscopy (SEM) was employed examine grains. A analytical approach developed using ultra‐high performance liquid chromatography with diode array detection quadrupole‐time‐of‐flight mass spectrometry quantitatively qualitatively analyze 17 acids. Discrepancies constituents were further explored partial least squares discrimination hierarchical clustering analysis. Results Microscopic examination revealed distinct species, could be distinguished SEM. The established these constituents—comprising 13 4 acids—proved reliable accurate. flavonoid glycosides categorized into three groups. TA, average contents 1, 2, 3, 4, 8, 12 higher than TO, whereas reverse true 7, 14, 16, 17. Constituents 9, 10, unique TO. And constituent 14 should chosen more appropriate indicator Chemometric techniques effectively differentiated TA Conclusions contributes enhancing control facilitating identification provides an experimental foundation improving its standards.

Moringa oleifera leaves (MOLs) have gained significant attention due to their nutritional and biological activity. Therefore, this study aimed examine its flavor characteristics underlying compositions. In study, we used ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS), gas chromatography-mass (GC-MS), electronic nose, tongue, molecular docking comprehensively investigate the chemical properties profiles of MOLs. UPLC-Q-TOF-MS GC-MS were instrumental in identifying 20 non-volatile 19 volatile constituents MOLs, respectively. The nose tongue systems provided an objective evaluation sweet, bitter, spicy attributes Concurrently, was employed elucidate material basis profiles. It revealed that glucosinolates flavonoids are probably key components for bitter taste sweet may be attributed flavonoids. scent appears linked presence alkaloids. integration these techniques confers a thorough understanding composition sensory These findings implications innovative applications food industry as well pharmaceuticals agriculture sectors; furthermore, they contribute towards enhancing perception valuable natural resource.
