*2.3. Subclass Cycadaceae*

The ethyl acetate extract of *Cycas rumphii* Miq. developed halos against *Staphylococcus albus* whereas the methanol extract (20 mg/mL solution per disc) hampered the growth of *S. aureus* and *E. coli* [22]. Later, the methanol extract of leaves (paper disc impregnated with 20 mg/mL solution) repressed *S. aureus* (ATCC 25953) [22]. Note that the Cycadaceae have not been much studied for their antimicrobial effects (Table 1) [23].
