Abstract Introduction Shenlingbaizhu granule, a Traditional Chinese Medicine prescription comprising Renshen, Gancao, and Shanyao, is widely consumed in China nowadays. Objective The study tries to propose pharmacopoeia quality markers (Q‐markers) prevent counterfeiting involving Shanyao. Methodology A novel strategy, that is, library‐based ultra‐high‐performance liquid chromatography–quadrupole‐orbitrap mass spectrometry, was used analyse the lyophilised aqueous powder of granule. Subsequently, quantum chemistry calculation UV‐vis spectra scanning were also performed through theoretical or experimental approaches. Result Thirty‐two isomers have been strictly distinguished, especially positional isomeric isochlorogenic acid B versus C, schaftoside isoschaftoside, ginsenoside Rg2 20S ‐ginsenoside Rg3, stereoisomeric Rg3 20R Rg3. Seventeen compounds unexpectedly observed, particularly scoparone pectolinarigenin, while total 76 bioactive putatively identified study. results revealed glycyrrhizic acid, Re, Rb1, diosgenin displayed different dipole moment values maximum absorption wavelengths from each other. Conclusion recommends as four anti‐counterfeiting Q‐markers for pharmacopoeia. can be detected using conventional HPLC. observation 17 unexpected updates our knowledge regarding bioactives

Identifying the catalytic regioselectivity of enzymes remains a challenge. Compared to experimental trial-and-error approaches, computational methods like molecular dynamics simulations provide valuable insights into enzyme characteristics. However, massive data generated by these hinder extraction knowledge about mechanisms without adequate modeling techniques. Here, we propose framework utilizing graph-based active learning from identify ginsenoside hydrolases (GHs), which selectively catalyze C6 or C20 positions obtain rare deglycosylated bioactive compounds

Ginseng, a cornerstone of traditional herbal medicine in Asia, garnered significant attention for its therapeutic potential. Central to pharmacological effects are ginsenosides, the primary active metabolites, many which fall within dammarane-type and share protopanaxadiol as common precursor. Challenges extracting ginsenosides from ginseng arise due their low concentrations roots. Emerging solutions involve leveraging microbial cell factories employing genetically engineered yeasts. Here, we optimized fermentation conditions via Design Experiment, realizing 1.2 g/L simple shake flask cultivations. Extrapolating setup complex like compound K, achieved 7.3-fold (0.22 g/L) titer improvements. Our adaptable enable production high-value products, such sustainable triterpenoids synthesis. Through synthetic biology, engineering, formulation studies, pave way scalable bioactive compounds ginseng.
