Epithelantha micromeris · Accepted scientific name
Scientific literature: Very Sparse (1 studies) · ★☆☆☆☆
Epithelantha micromeris is a diminutive, button-like cactus native to the arid regions of Mexico. While its tiny, geometric form makes it an attractive specimen for collectors, it possesses certain biological properties that warrant caution. Scientific investigations into the plant have focused on the development of ethanolic extracts to study its complex chemical makeup. These concentrated preparations have revealed that the species contains bioactive compounds with significant physiological effects. Consequently, the plant is classified as toxic, requiring careful handling to avoid accidental ingestion or exposure.

Biological Activities
Epithelantha micromeris, commonly known as the button cactus, has been identified as containing bioactive compounds with toxic properties. Scientific investigations involving ethanolic extracts of the plant demonstrated significant toxicity in mouse models. Through the process of acid hydrolysis, researchers were able to isolate several crystalline substances from these toxic extracts. Among the identified components were known triterpenes such as oleanolic acid and the plant sterol beta-sitosterol. The study further revealed the presence of potentially new compounds, including epithelanthic acid and methyl epithelanthate.
Compounds
Epithelantha micromeris, commonly known as the button cactus, serves as a unique source of various bioactive triterpenes. Chemical analysis of its ethanolic extracts has revealed the presence of several distinct crystalline compounds. Notably, the plant contains the common plant sterol beta-sitosterol. Researchers also identified the presence of the known triterpene oleanolic acid within its chemical makeup.
