Abstract BACKGROUND Sanqi, the root of Panax notoginseng , has long been recognized for its therapeutic effects on cardiovascular diseases. Saponins, including ginsenosides and notoginsenosides, are main bioactive components P. . The biosynthesis saponins is closely related to defense responses orchestrated by endogenous hormones. RESULTS To provide new insights into underlying role phytohormone jasmonic acid (JA) in synthesis regulation saponins, we performed an ultra‐performance liquid chromatography analysis different tissues aged 2–4 years. Moreover, combined evaluation saponin content transcriptome profiling each tissue, spatial temporal distribution was analyzed. N notoginsenoside R1, ginsenoside Rb1 Rd accumulated underground tissues, root, tuqi, fibril rhizome. In agreement with this data, corresponding genes hormone JAs, especially coronatine insensitive 1 ( COI1 ) myelocytomatosis proteins 2 MYC2 ), were predominantly expressed tissues. tissue‐ age‐specific consistent expression involved JA biosynthetic, metabolic signaling pathways. CONCLUSION present study revealed phtohormones which will a significant impact improving ecological planting technology, cultivating high‐quality varieties protecting rare resources medicinal notoginseng. © 2024 Society Chemical Industry.
