[Analysis of chemical composition of Salvia miltiorrhiza flower by GC-MS].

To analyze the chemical constituents of Salvia miltiorrhiza flower. Extraction liquid separated in alumina silica column (alumina: silica = 3: 9). Mixed solution of hexane (100 mL) and dichloromethane (50 mL) eluted and got first fraction. Then, methanol (100 mL) eluted and got second fraction. Two fractions were analyzed with GC-MS. The main components of the first fraction were nonacosane and hentriacontane and that of the secend fraction was hexadecanoic acid. This study provides theoretial basis for further study of Salvia miltiorrhiza flower.
