citratus had different major compounds, besides showing remarkably higher percentage of volatile geranial and neral terpenoids in species distributed in Brazil (GUIMARAES et al., 2011) and in other countries (AVOSEH et al., 2015).
Again, differences were observed among the three studied citrus fruits, with the following five compounds predominating in: SoLi: limonene (35.8%) > linalyl acetate (17.1%) > [beta]-pinene (11.3%) > linalool (4.6%) > [beta]-bisabolene (4.2%); SwLi: limonene (40.9%) > [beta]-pinene (16.6%) > linalyl acetate (16.1%) > linalool (7.7%) > [alpha]-pinene (3.8%); and, SwLe: limonene (35.9%) > [beta]-pinene (15.7%) > [gamma]-terpinene (8.7%) > geranial (4.9%) > [alpha]-pinene (4.4%).
The average rate of limonene and geranial was 17% and 9%, respectively, in different essential oils distilled from A.
This indicates that the plant belongs to the "citral" chemotype composed of neral + geranial [21].
In this context, monoterpene citral, an isomeric mixture of neral and geranial, a component of lemongrass oil, has been reported to have many biological activities such as antibacterial and anti-inflammatory activities [8-10].
The major constituents of the oil are linalool, linalyl acetate, cineol, pinene, limonene, geranial, borneol and some tannin [5].

The inhibitory effect of ginger against microorganisms tested could be due to the presence of many active compounds like zingiberene, zingerone, shagaols, gingerols and geranial. These are terpenoids and have lipophilic properties.
(2002) reported that the main components of citrus essential oils were limonene, [beta]-pinene, myrcene, neral, geranial, neryl acetate and P-caryophyllene.
The chromatographic analysis carried out for the essential oil allowed the identification of citral (neral + geranial isomers) in the AndrE da Rocha population, ledene and caryophyllene in Bom Jardim da Serra and limonene, borneol, 1,3,8-menthatriene and 1,5,8 p-menthatriene in Santa Lucia as major compounds.
