Chemical constituents of Tilia taquetii leaves and their inhibition of MMP-1 expression and elastase activities.

The ethanol extract of Tilia taquetii Schneider leaves was investigated for its anti-wrinkle properties and for the relevant chemical constituents. Phytochemical studies led to the identification of five known compounds, viz. phytol (1), isoquercitrin (2), oleanderolide (3), arjunolic acid (4) and maslinic acid (5) from the extract.

Effects of Machilus thunbergii Sieb et Zucc on UV-induced photoaging in hairless mice.

Chronic ultraviolet (UV) exposure induces photoaging and oxidative stress in the skin. We investigated whether Machilus thunbergii Sieb et Zucc (M. thunbergii) could reduce UV-induced photoaging and oxidative stress in hairless mice.
