Gas Chromatographic Analysis of Bioactive Compounds in Rothmannia whitfieldii and Penthacletra macrophylla, Lonchocarpus cyanescens Curcuma longa and Duranta repens
This study characterized the bioactive components in Rothmannia whitfieldiiand Penthacletra macrophylla, Lonchocarpus cyanescens Curcuma longa and Duranta repens to establish its usefulness in replacing costly synthetic dyes. Identification and quantification of the bioactive attributes were performed using gas-liquid chromatography with flame ionization detector (GC-FID) after extraction with n-Hexane. The results further revealed the identity of the following bioactive compounds present in the GC-MS analysis carried on the plant extracts: 2-Methoxy-4-vinylphenol in LCE & CLE; LCE, Dodecanoic acid, methyl ester in DRE, & RWSHE; Methyl tetradecanoate in LCE, DRE, & RWSHE; Di-sec-butyl phthalate in LCE, DRE, & RWSHE; Hexadecanoic acid, methyl ester in LCE, CLE RWSHE, RWSE, & PME; n-Hexadecanoic acid in LCE, DRE, & RWSE; Oleic Acid in LCE, DRE, RWSE, & PME; 6-Octadecenoic acid, (Z)- in LCE, DRE, & PME; 2,3-Dihydroxypropyl elaidate in LCE & PME; Benzene, 1-(1,5-dimethyl-4-hexenyl)-4-methyl- and aR-Turmeronein CLE & PME; cis-13-Octadecenoic acid, methyl ester in CLE & RWSE; Dodecanoic acid in DRE, RWSE, RWSHE, & PME; Methyl 13-methyltetradecanoate in DRE & RWSHE; 9-Octadecenoic acid in DRE, RWSE, RWSHE, & PME; Hexadecanoic. The plant used in this study (Curcuma longa, Pentclethra macrophylla, Duranta repens, Lonchocarpus cyanescens, and Rowthmania whitfieldii) may serve as an eco-friendly alternative to their synthetic counterparts and cost effective biological stains.
