ISOLASI DAN PENENTUAN STRUKTUR KANDUNGAN KIMIA EKSTRAK ETANOL KULIT BATANG JOHAR (CASSIA SIAMEA LAMK.)

Preliminary study of chemical content of the bark of "Johar" (Cassia siamea Lank., Caesalpiniaceae) showed the presence of alkaloid, flavonoid, tannin, quinone and steroid/ triterpenoid. Iron, magnesium, copper, zinc and calcium were found in the ash of the bark. Separation was done by liq...
