The chemistry is the science about elements and its properties.

One of the most popular problem for modern chemists is the searching for molecules, that could be bioactive.

Firstly, you need to find any sample of the plant, after that required to extract active compound.

There is much reason for worry, this is because more than one compound you can get from your sample - is the contaminant, which must be deleted by purification.

Next step of the searching compound is the determination of the structure by the mass, infrared, and NMR H spectrometry.

1) Mass spectrometry: As you can read, there is the determination of the mass the molecules, that you've already extracted and purified from the sample.

In the mass spectrum, you can get more peaks, however, the heaviest one is the right.

A number of peaks are varied in the wide scale, although it is not quite important for the determination.

2) Infrared spectroscopy: By the infrared spectroscopy is determined the functional groups.

3) NMR H spectrometry: One of the most popular methods of the determination of the structure's carbon chain.

Likewise others you get the peaks in the spectra, but there is not only one, the symmetry of the molecule plays the main role in the determination, as the atoms of the hydrogen could relate to its resonate's frequency.
