ABSTRACT: The core of the natural product chemistry laboratory is isolation
secondary metabolites. One
of the potential secondary metabolites for isolation in the natural product
chemistry laboratory is routine (quercetin-3-O-glycosides). Routine (Quercetin-3-O-glycoside)
has been isolated from ethanol extract of rubber cassava leaves (Manihot glaziovii MA). Isolation was
done by maceration and recrystallization. The isolation method used in this
study is complemented by the isolation method published. The isolated
(Quercetin-3-O-glycoside) routine using this method obtained a yield of 0.118%
of the total dried leaf extract. The routine (Quercetin-3-O-glycoside) was
identified using a standard routine. Routine can be further utilized in the
world of medicine as an amplifier of capillary structure, reducing the
permeability and fragility of blood vessels.
