Description
Hongwei Sun and six colleagues stress, in a 2026 laboratory study, the medicinal herb Panax notoginseng with simulated drought to see how water shortage changes its chemistry and prized active compounds. The plant is valued for saponins used against heart and brain vessel disease, and climate change is drying its growing regions.
Seedlings tolerated moderate doses of a drought-mimicking chemical for a week, yet growth, pigments, and protective enzyme activity all shifted markedly. Stress markers rose in leaves and roots, while five key saponins peaked at a middle dose rather than the harshest one. Chemical profiling found more than eleven thousand changed metabolites, concentrated in fat, amino acid, and pigment pathways. The results guide watering decisions for quality harvests.
