Abstract
Gynura procumbens (Lour.) Merr, known in Jakarta as
Sambung nyawa is a tradi tiona! medicinal herb from the
Compositae Family, which is believed to be useful as a
febrifuge in a few eruptive fevers, in the treatment for
rash, as a remedy for kidney trouble, prevention of
rheumatism, eliminate lethargy especialli in old people
and for colon cancer and haemarrhoids.
The aim of this study is to ·determine the chemical
components and pharmacognosical parameter for Gynura
procumbens herb. The dried powdered leaves of the herb
was extracted continuously with petroleum ether (60-
B00C) , chloroform and methanol. Three classes of compounds
were isolated from the petroleum et!"ter extract;
nonadecane (saturated acyclic hydrocarbon), phytyl valerate
(ester of acyclic diterpenoid) and a mixture of asitosterol
and stigmasterol (steroid).
Isolation of the chloroform extract afforded sterol
glycosides, a m. ixture of a-si. tosterol and stigmasterol
glucosides which was further confirmed by conversion to
the corresponding acetate with pyridine-acetic anhydride.
Nucleic acid adenosine and two flavonoid glycosides
kaempferol 3-0-glucoside and kaempferol 3-0-
neohesperidoside were isolated from the methanol extract
of the leaves.
