موضوع به انگلیسی:A simple method to obtain ursolic acid
بخشی از متن:A simple method has been developed to obtain ursolic acid (UA) by crystallization and recrystallization of the
ethanol extract of Clinopodium revolutum. Its structure was confirmed by 1D (1H‐, 13C‐, DEPT 45, 90 and 135)
and 2D (COSY, HMBC and HSQC) nuclear magnetic resonance (NMR) spectroscopy and Fourier transform
infrared spectroscopy (FT‐IR). The results provide a theoretical basis for considering the species Clinopodium
revolutum with a source of UA
