Phytochemical Insights and Medicinal Potential of Panax notoginseng: A Comprehensive Study from Chiang Mai

Panax notoginseng, a prominent medicinal plant, was studied to evaluate its phytochemical composition, cultivation practices, and therapeutic potential using samples from Chiang Mai, Thailand. Phytochemical analysis revealed high concentrations of bioactive compounds, including ginsenosides (notoginsenoside R1, ginsenoside Rb1, and ginsenoside Rg1), with average levels of 2.5 mg/g, 3.8 mg/g, and 3.1 mg/g, respectively. UV-visible spectrophotometry indicated total flavonoid and polysaccharide contents of 7.4 mg/g and 6.1 mg/g, respectively. These findings suggest that the Chiang Mai region offers an optimal environment for cultivating Panax notoginseng, potentially enhancing its antioxidant and immune-modulatory properties. Surveyed local farmers identified key factors influencing phytochemical composition, including consistent irrigation, pest management, and soil quality. A positive correlation (r = 0.72, p < 0.05) was observed between organic farming practices and higher concentrations of ginsenoside R1, indicating that sustainable cultivation methods may improve medicinal quality. Despite promising results regarding the therapeutic potential of ginsenosides, especially for cardiovascular conditions, there is a need for further research to address safety concerns and drug interactions. Clinical trials are recommended to evaluate the long-term effects of Panax notoginseng in diverse populations. This study underscores the potential of Chiang Mai as a significant source of high-quality Panax notoginseng, with implications for improving cultivation practices and meeting global herbal medicine demands. Future research should focus on refining cultivation techniques and assessing the plant's safety profile.
