Chromone Derivatives Of Cassia pumila and their Anti-MRSA Activity
Two new ( 1 and 2 ) compounds, together with five known ( 3–7 ) chromone derivatives, were isolated from the whole plants of Cassia pumila. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds 1–7 were evaluated for their anti-methicillin...

| Zusammenfassung: | Two new (
1
and
2
) compounds, together with five known (
3–7
) chromone derivatives, were isolated from the whole plants of Cassia pumila. Their structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Compounds
1–7
were evaluated for their anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) activity. The results revealed that compounds
