The main components of the hexane extract were 9-octadecenoic acid([omega]-9), 9, 12- octadecadienoic acid (linoleic acid or [omega]- 6), hexadecanoic acid, (palmitic acid), 1,2-benzenedicarboxylic acid diisooctyl, dodecane and [gamma]- linolenic acid.
The GC-MS analysis of water extract from calyxes of karkade showed that untreated plants contain 4 bioactive constituents: 3,7,11,15-tetramethyl-2-hexadecen-1-ol; 1,1-bicyclohexyl, 2-(2-methylpropyl)-trans; 3-buten-2-one,4(2-hydroxy-2,6,6-trimethylcyclohexyl); and 1,2-benzenedicarboxylic acid, diisooctyl ester (Table 4).
Those compounds' names and retention times (RT) are 1,2-benzenedicarboxylic acid, dibutyl ester at 5.76 min, hexadecanoic acid, methyl ester at 6.374 min, hexadecanoic acid, 15-methyl-, methyl ester at 7.908 min, 9,12-octadecadienoic acid (Z,Z)-methyl ester at 9.141 min, 8-octadecenoic acid, methyl ester at 9.238 min, and methyl stearate at 9.688 min.
These were: 1-Isopropyl-2, 2-dimethylpropylideneamine, Camphor, Naphthalene, Thymol, 1,5,5- Trimethyl-6-x methylene-cyclohexene, Hexadecanoic acid, methyl ester, 9,12,15 Octadecatrienoic acid, methyl ester, 8, 11, 14-Eicosatrienoic acid and 1,2-Benzenedicarboxylic acid, mono(2-ethylhexyl) ester.
This table shows that 1,2-benzenedicarboxylic acid, mono (2-ethylhexyl) ester (21.04%), [gamma]-sitosterol (16.42%), and 3,7,11,15-tetramethyl-2hexadecen-1-ol (6.34%) are the three main components, followed by hexadecanoic acid, ethyl ester (4.77%), phenol, 2,2'-methylene bis (4.53%), (E)-9-octadecenoic acid ethyl ester (4.11%), and hexadecanoic acid, methyl ester (4.08%).
