Scientific literature: Very Sparse (1 studies) · ★☆☆☆☆
Aesculus pavia, commonly known as the redbud maple, is a striking ornamental tree recognized for its vibrant red flower clusters. While visually stunning, certain components of the plant require cautious handling due to their chemical properties. Specifically, the leaves of this species contain a notable chemical compound known as pavietin. Because of these substances, various activities involving the plant can be considered toxic if ingested or mishandled. Understanding these biological risks is essential for anyone interacting with this beautiful yet chemically complex specimen.

Biological Activities
Aesculus pavia is highlighted in Alexander von Humboldt's historical manuscript, "Plantae des États-Unis," for its specific biological properties. Within this detailed collection of annotations from the early nineteenth century, the species is explicitly categorized by its toxic activity. This classification serves as a vital piece of ethnobotanical data retrieved from Humboldt's observations of North American flora. Such records provide a glimpse into how various plants were perceived and documented by European naturalists during their expeditions. Ultimately, identifying the toxicity of Aesculus pavia helps researchers reconstruct the historical landscape of plant utility and knowledge in the USA.
Compounds
Aesculus pavia serves as a rich source of diverse phytochemical compounds, including the notable prenylated coumarin known as pavietin. Research has identified that this specific plant genotype also contains several important flavonol glycosides. Specifically, the leaves of Aesculus pavia harbor quercetin-3-O-alpha-arabinoside and quercetin-3-O-alpha-rhamnoside. While pavietin demonstrates significant antifungal activity against pathogens like Guignardia aesculi, the glycosides alone show much weaker biological effects. Understanding these chemical relationships is essential for exploring how such compounds contribute to the plant's natural resistance.
Conditions
Aesculus pavia possesses unique chemical properties that allow it to combat specific biological threats. The plant contains a coumarin known as pavietin, which demonstrates significant antifungal activity against the parasite Guignardia aesculi. This specific compound appears to play a vital role in the plant's natural resistance to fungal pathogens. Beyond its antimicrobial capabilities, historical ethnobotanical records from Alexander von Humboldt's manuscripts identify Aesculus pavia as a toxic species. Consequently, the plant is characterized by both its ability to treat fungal infections and its inherent toxicity.
Preparations
Parts used
Aesculus pavia serves as a vital source of bioactive compounds, particularly within its foliage. Researchers have successfully isolated a specific prenylated coumarin known as pavietin from the leaves of this plant genotype. This chemical constituent, found alongside various flavonol glycosides, demonstrates significant antimicrobial properties. Notably, pavietin exhibits appreciable antifungal activity against Guignardia aesculi, a major fungal parasite affecting the species. The presence of this leaf-derived compound may play a crucial role in the plant's natural resistance to disease.
