Phytochemical analysis of the leaves of Chromolaena odorata (Asteraceae) / Nuha Che Man

Che Man, Nuha (2010) Phytochemical analysis of the leaves of Chromolaena odorata (Asteraceae) / Nuha Che Man. Degree thesis, Universiti Teknologi MARA.


Chromolaena odorata is a species from family of Asteraceae. Most of the phytochemical
surveys carried out on in this family were concentrated on the testing on flavonoids since
flavonoids were generally proven to be effective as therapeutically agents. Not only that, other
compounds present in the plant also have been studies. Therefore a study on chemical
constituents of the stem of Chromolaena odorata (500g) was conducted. The crude extracts
were obtained by extraction by using hexane and methanol. The crude extract obtained from
dichloromethane is 3.88g, isolation works were carried out using various chromatographic
techniques. That result in a mixture of the compounds was founds. These mixtures known as 4’,
5-dihydroxy-3, 7-dimethoxyflavone and another are types of flavonone. These structures are
identified based on spectroscopic analysis using 1H NMR, 13C NMR, APT, HMQC Nuclear
Magnetic Resonance (NMR)
