GC-MS Analysis of n-Hexane Extracts of Hibiscus micranthus Linn.

Abstract

Hibiscus micranthus

Linn., is an undershurb which grows wild in India, Ceylon, tropical African-hexane extracts of Hibiscus micranthus Linn., with the help of GC-MS technique. The

n-

hexane extraction of the powder of dried leaves, stem and root parts of Hibiscus micranthus

Linn., by Soxhlet extraction yielded thick green residue (leaves and stems) and red thick residue

(roots), respectively, which were analyzed by the GC-MS. A total of 23 compounds were identified

from the

extract are

tetramethyl, 1-octanol-2-butyl, cyclopentadecanol, octadecane, phosphonofluoridic acid

(1-methylethyl)-cyclohexyl ester. However cylcopentadecanol was the most abundant followed

by oleic acid. From the

acid-14-methyl, methyl ester, 9,12-octadecadienoic acid methyl ester, cyclopropanepentanoic

acid-2-undecyl-methyl ester and oleic acid were the major components of the stem extract and

the oleic acid was the most abundant one. Thirty nine compounds were identified from the GCMS

analysis of the

dihydrocarveol, 1,2,4-trioxolane-2-octanoic acid 5-octyl-methyl ester,

ester, 4-germaspiro(3,4)octane, cinerin-II, 4-decen-6-ynedioic acid dimethyl ester, 1-

1,25-dihydroxycholecalciferol, naptho(3,2,1-c,d)isoindol-4(5

, 1,3,2-dioxarsenane-4-methyl-2-phenyl-, methyl-2,3,4-tri-O-acetyl-6-O-methyl-

1,2-dicarbadodecaborane 1-hexyl- and 1,2,3,6,9-pentaazaspiro(4,4)non-2-

ene,1,4,4,6,9-pentamethyl-, were the major components of the root extract and cinerin-II was

the most abundant one followed by 4-germaspiro(3,4)octane. The GC-MS analysis revealed

that the

aldehydes and ketones (together 13.8 %), sulphur compounds (8.3 %), fatty acids, esters and

alcohols were least (5.5 %), while stem extracts composed fatty acid esters (33.3 %) followed

by fatty acids (14.8 %) and least in hydrocarbons (3.7 %). The non-polar root extract composed

fatty acid esters (19.1 %) followed by aldehydes and ketones (13.2 %), hydrocarbons (10.2 %),

fatty alcohols (8.8 %) and least were fatty acids. It is concluded that the

leaf, stem and root of

of phytopharmaceutical importance.

and in Ceylon. The current study is aimed at to characterize the non-polar chemical components
