Aislamiento e identificación del diterpeno carnosol a partir de las especies vegetales Lepechinia mutica Benth y Rosmarinus officinalis Linneo.

Abstract

In the present investigation, by means of chromatographic techniques, two terpenes were isolated from Lepechinia mutica Benth and Rosmarinus officinalis Linneo species. The species L. mutica was collected in the Quilanga canton of the province of Loja and R. officinalis was purchased in the Mercado Mayorista of the city of Loja. From the methanolic extract of L. mutica, a tricyclic diterpene called carnosol was isolated and identified. A pentacyclic triterpene known as betulinic acid was also isolated and identified from the methanolic extract R. officinalis. The identification and characterization was performed by Nuclear Magnetic Resonance (NMR) 1H, 13C, melting point and retention factor.
