Objective: To study the chemical constituents in roots of Peucedanum praeruptorum from Henan.
Method: The constituents were isolated by column chromatography on silica gel and ODS, and identified by NMR, MS spectroscopic methods.
Result: Six compounds, Pd-I b(1), marmesinsin (2), rutarin (3), isorutarin (4), 4H-1-benzopyran-4-one, 5-hydroxy-6-methoxy-2-phenyl-7-O-alpha-D-glucuronyl methyl ester (5), 4H-1-benzopyran-4-one, 5-hydroxy-6-methoxy-2-phenyl-7-O-alpha-D-glucuronyl acid (6) were isolated and identified.
Conclusion: Compound 5 was a new compound, compounds 5 and 6 were isolated from Peucedanum plant for the first time.

Super-resolution methods provide far better spatial resolution than the optical diffraction limit of about half the wavelength of light (∼200-300 nm). Nevertheless, they have yet to attain widespread use in plants, largely due to plants' challenging optical properties. Expansion microscopy improves effective resolution by isotropically increasing the physical distances between sample structures while preserving relative spatial arrangements and clearing the sample.

Background: Pregnancy, a transformative phase, is often fraught with considerable psychological stress. Within the context of Chinese culture, characterized by intricate family dynamics, societal expectations, and deeply rooted traditional beliefs, the manifestation of stress during pregnancy may present with distinct nuances. The adaptation and validation of the Perceived Stress Scale (PSS-10) for the Chinese context are pivotal for a nuanced understanding and effective intervention for the stressors encountered by pregnant women in China.

Etnopharmacological Relevance: The Convolvulaceae or morning glory family, with about 2000 species in the world's Tropics and subtropics, stands out among the plants used in traditional medicine. Medicinal plant complexes with important purgative properties have been developed in Mexico and Brazil from members of the genera Ipomoea and Operculina with storage roots. Popularly known as the jalap roots, their resin glycosides cause purgative and laxative activities that facilitate bowel movements.
