Phytochemical research on an extract of Notopterygium incisum yielded fifteen compounds (1-15), including four previously undescribed compounds (10-13). The structures of the unreported compounds were elucidated by spectroscopic and spectrometric data analysis such as 1D and 2D NMR, IR and HR-ESI-MS. Compounds 1-5 and 10-14 were isolated from N.

Their structures were determined by spectroscopic data analyses such as HR-ESI-MS, 1D, and 2D NMR, as well as comparison with literature data. At the same time, the absolute configuration of five compounds 2-5 and 10 was confirmed for the first time by the single crystal X-ray diffraction method.

- Oxygen is super important for living things, and not having enough can cause health problems, especially at high altitudes or with breathing issues.
- Gypenosides, a special ingredient from a plant called Gynostemma, help protect cells from damage caused by low oxygen levels.
- In tests, gypenosides helped mice survive longer in tough conditions and improved their movement, showing they might be useful for fighting diseases caused by lack of oxygen.
