| Three popular medicinal plants from Mexico possessing renal activity and similar pharmacologic properties were selected for study: (1) Eysenhardtia polystachye (Fabaceae), commonly known as Palo Azul; (2) Equisetum avvense (Equisataceae), commonly known as Cola de Caballo; and (3) Amphipterygium adstringens (Julianiaceae), commonly known as Cuachalalate. Our research objective was to identify the natural chemical components common to each of the plants. The barks of Palo Azul and Cuachalalate, and the leaves of Cola de Caballo were pulverized and extracted successively in a Soxhlet apparatus with solvents of increasing polarity; (1) petroleum ether, (2) anhydrous diethyl ether, (3) chloroform, and (4) absolute ethanol. Separate plant samples were extracted with dichloromethane and de-ionized water. The aqueous infusions were extracted in a separatory funnel with dichloromethane. All extracts were evaporated to dryness and the residues dissolved in anhydrous dichloromethane. Samples were concentrated, filtered, dried with anhydrous sodium sulfate and analyzed with a GC-MS. |
