Chemical Constituents From Phalaenopsis Hybrids and Their Bioactivities

One new flavone glycoside and 11 known compounds were characterized from the methanolic extracts of Dtps. Tinny Ribbon × Dtps. Plum Rose (Phalaenopsis hybrids) by nuclear magnetic resonance and mass spectrometric analyses. In addition, the major pigment constituents 1 to 3 were examined for their antioxidant and antityrosinase activities. The experimental results indicated that the Phalaenopsis flower extracts were potential for developing new cosmetic products
