Esters constituted the largest family and included acetates (ethyl, propyl, isobutyl, butyl, isoamyl, and phenethyl), ethyl esters of fatty acids (propanoate, isobutanoate, butanoate, hexanoate, octanoate, 3-hydroxybutanoate, 3-hydroxyhexanoate and furcate), ethyl esters of organic acids (pyruvate, lactate, ethyl myristate, diethyl malate and, mono- and diethyl succinate) and various other esters, such as methyl butanoate, isobutyl lactate and phenylethyl octanoate. The acids quantified included isobutanoic, butanoic, hexanoic, octanoic, decanoic, lauiic and 3-methylbutanoic. The lactones included y-butyrolactone, pantolactone, y-decalactone and E- and Z-oak lactone and the terpenes included neral d-terpineol, P-dtronellol and Z-nerolidol. The aldehyde family comprised acetaldehyde, benzaldehyde, furfural, 5-methylfurfural and octanal, and the phenol family included eugenol, 4-ethylphenol and 4-ethylguaiacol. Finally, 1,1-diethoxyethane, acetoin, sotolon, 2, 3-butanedione, p-cymene and methionol were also determined. 

This oil consists mainly of linalol, together with small quantities of methyl heptenone, geraniol, and d-terpineol. 

The oil contains some 90 per cent, limonene, together with nonyl alcohol, d-linalol, d-terpineol, citral, citronellal, decyl aldehyde, and methyl anthranilate. 

Schimmel Go. have shown that geraniol and d-terpineol are present in the oil as well as small quantities of cineol, dipentene, furfurol, and mbably) isovaleric aldehyde, and Boure-Bertrand Fils have isolated methyl-heptenone and nerol from it. The last-named give the following as the composition of the oil —... 

The oil consists principally of dextro-limonene which is present to the extent of about 90 per cent, or ever. Decylic aldehyde is one of the principal odorous constituents of the oil linalol, 2-terpineol, d-terpineol, nonyl alcohol, methyl anthranilate and traces of caprylic acid esters are also present. 

Tbe oil contains a considerable amount of tni-pinyl acetate ( therefore requires at least two hours for complete saponification), terpineol was identified as d-a-terpiucol by ficbimmel A- Co, The pene terpinene has been stated to be present, hut this is not conhri by the author, nor hv Schimmel A Co. Limoneue is probably pre iu atnall amount. Free terpineol is also present.

GC-MS. The major compounds were found to be trans-linalool oxide and a-terpineol, whereas the dry black pepper oil contained a- and (3-pinenes, d-limonene and (3-caryo-phyllene as major components. When fresh pepper oil was isolated by distillation and analysed by GC and GC-MS, the compounds were found to be of a different nature to that of fresh pepper aromatic compounds (Menon, 2000). 

The large cardamom pericarp (husk) yielded 0.18% volatile oil by the Clevenger hydrodistillation method. This oil was analysed for physical parameters, e.g. specific gravity (0.9148), refractive index (1.4733) and optical rotation (-7.700). The volatile oil was subjected to GC-MS analysis and 37 compounds were identified, constituting > 98% of the total oil. The major compounds characterized were 1,8-cineole (38.7%), [3-pinene (13.6%), a-terpineol (12.6%), spathulenol (8.3%), 4-terpineol (4.5%), ger-macrene D (3.0%), a-pinene (2.8%) and (3-selinene (2.7%). GC and GC-MS data revealed that 1,8-cineole content was less than 50% when compared with the seed oil. Table 4.5 shows the major constituents separated by GC-MS (Rout et al., 2003). Figure 4.1 gives the structures of the major chemical components in the volatile oil from seeds.

Another contamination of citrus peel oils comes from chlorine-treated water used in the oil recovery process and sanitizers used in postharvest handling and process equipment cleaning, which serve as a potential source of hypochlorous acid (HOCl) (73). HOCl can react with a variety of terpenes similar to d-limonene in structure, including hmonene, a-pinene, and a-terpineol, resulting in the formation of terpene chlorohydrins. The contamination of terpene chlorohydrins could be reduced through reduction of the chlorine levels in the treatment water (74).
