Bioactive natural compounds from Prosopis africana and Abies nobili.

Chromatographic procedures from the aerial parts of Abies nobilis and stem barks of Prosopis africana led to the isolation of two (antimicrobial and cytotoxic) compounds. Their structures were established as 7, 3’, 4’- trihydroxy-3-methoxyflavanone and dehydroabietic acid on the basis of spectroscopic techniques.
