Zusammenfassung: | Phytochemical investigations of the acetone extract of
Psidium guaijava seeds has led to the isolation of two new phenylethanoid glycosides (
1 and
2) and their investigation for their pharmacological activity.
Phytochemical investigations of the acetone extract of
Psidium guaijava seeds has led to the isolation of five known flavonoid glycosides, two phenolic glycosides and two new phenylethanoid glycosides which have been identified as 1-
O-3,4-dimethoxy-phenylethyl-4-
O-3,4-dimethoxy cinnamoyl-6-
O-cinnamoyl-β-
d-glucopyranose and 1-
O-3,4-dimethoxyphenylethyl-4-
O-3,4-dimethoxy cinnamoyl-β-
d-glucopyranose, on the basis of chemical, physical and spectroscopic methods of analysis. |
