What are the morphological characteristics of this plant?
Paeonia mairei has a perennial rhizomatous habit characterized by large, deeply lobed, pinnatisect leaves and solitary, large flowers that typically measure between 10 and 15 centimeters in diameter. The foliage is composed of several leaflets that are broadly ovate or elliptical with serrated margins. Its flowers feature numerous bright red or pink petals surrounding a central cluster of many prominent stamens. The plant produces woody stems that emerge from thick underground rhizomes to support the heavy floral displays. These morphological traits distinguish it from other members of the Paeoniaceae family found in similar alpine environments.
What is the geographical distribution of this plant?
This plant is endemic to the mountainous regions of central and western China, primarily spanning provinces such as Sichuan, Gansu, and Shaanxi. It thrives within specific high-altitude habitats ranging from temperate forests to scrublands. The species is typically found growing on rocky slopes and in shaded woodland areas where soil moisture is consistent. Its distribution is restricted by these specific topographical and climatic requirements, making it a localized component of the Chinese flora. Localized populations often occur in fragmented pockets across the rugged terrain of the Qinling and Minshan mountain ranges.
How is this plant cultivated?
This plant requires well-draining, fertile soil and a location with full sun to moderate shade to ensure successful cultivation.
It thrives best when planted in cool, moist environments that mimic its natural mountain habitats. During the growing season, consistent watering is essential to prevent the root system from drying out completely. Providing a layer of organic mulch helps maintain soil moisture and regulates temperature around the rhizomes.
Once established, the plant is relatively hardy but benefits from being protected from extreme summer heat.
What parts of this plant are used medicinally?
This plant Paeonia mairei is utilized medicinally through the application of its roots and seeds. The roots are often processed to create decoctions that serve as traditional remedies for various ailments. These root extracts are frequently valued for their potential pharmacological properties in treating inflammation. Additionally, the seeds can be employed in specific herbal formulations depending on the desired therapeutic effect. Both plant parts are carefully prepared to ensure their bioactive compounds are effectively utilized in medicinal practices.
According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", the roots of seven Sect. Paeonia species, including P. mairei, were studied anatomically. These species show differences in microstructure that can be used to distinguish them. Distinct growth rings are formed in the roots of the seven Sect. Paeonia species because xylem vessels in the secondary xylem form clusters in tangential directions. The study used conventional paraffin section and freehand section to conduct this anatomical study on the roots. These growth rings provide a basis for age identification and quality evaluation of Paeoniae Radix Rubra.

What are the pharmacological activities of Paeonia mairei?
This plant has antioxidant, anti-inflammatory, analgesic, antipyretic, and hepatoprotective pharmacological activities. These therapeutic properties are primarily attributed to the presence of bioactive compounds like paeoniflorin and various phenolic acids. The antioxidant mechanisms help reduce oxidative stress by neutralizing free radicals within biological systems. Anti-inflammatory and analgesic effects allow the plant to mitigate pain and swelling through the inhibition of specific inflammatory mediators. Additionally, its hepatoprotective qualities suggest a significant role in protecting liver cells from chemical or toxic damage.
As discussed in a study, Paeonia mairei was grouped individually into a group via hierarchical cluster analysis. This classification was based on its relatively highest monoterpene glycosides and total phenolic content (TPC) content. The study assessed the application value of seeds from 12 species and 2 subspecies through various in vitro biochemical methods. These methods included four different antioxidant assays, specifically DPPH, ABTS, FRAP, and HRSA, alongside antibacterial and antifungal assays. The research also utilized HPLC-MS to qualitatively and quantitatively measure 25 individual chemical compounds.
