1The Key Laboratory of Academician Pei-gen Xiao Guangxi, Guangxi Medicinal Plant Garden, Nanning 530023, China.
Objective:
To study the chemical constituents of Teyou 2 Folium Mori.
Methods:
The compounds were extracted and isolated by CO2 supercritical fluid extraction, 30% alcohol extraction, macroporous resin and silica gel column chromatography and their structures were elucidated by means of melting point, TLC and spectral analyses.
Results:
Six compounds were identified as beta-carotene (I), oleanolic acid (II), benzoic acid (III), chlorogenic acid (IV), lysine (V), gamma-aminobutyric acid (VI).
Conclusion:
Compound II and V are isolated from this plant for the first time.
