The main components of chamomile plant include Alfa bisabolol, Bisabolol oxide, spiro ether, Chamazulene
, and flavonoids such as Apigenin and Luteolin.
The two key constituents, (-)-alpha-bisabolol and chamazulene
, account for 50-65 percent of total volatile oil content.
Chamomile's main active constituents are chamazulene
, apigenin, and bisabolol.
Isolated azulene chamazulene
 from the species was emitted at 425-430 nm , while most of flavonoids were at 460-490 nm .
0.1 and 0.2% Main components: camphor chiliophyllum (A) (32.5, 36.2), 1,8-cineole (1.6,16.1), chamazulene
(9.2, 2.9), pinocarvone (3.2, 2.4), hotrienol (2.7, 0.3), borneol (2.7, 2.8), chrysanthenyl isovalerate I (2.0, 3.0), chrysanthenyl isovalerate II (2.1, 2.8), [beta]-eudesmol (4.7,1.1) T.
Fifteen components of the oil were identified corresponding to a 98.55%, the major ones are [gamma]-palmitolactone (54.0%), 1-epi-cubenol (9.6%), [delta]-cadinene (6.1%), t-cadinol (5.0%) and chamazulene
For example, when used topically or internally, the apigenenin, chamazulene
(and its precursor, matricin), and other volatile oil constituents of chamomile flowers have been shown to help relieve muscle spasms.
The advantages of using chamomile preparations are connected to the presence of quite a few plant metabolites from various classes including flavonoids, coumarins, proazulenes, their degradation product chamazulene
, and the essential oil.
The active constituents are present in the dried flowers, and include: terpenoid volatile oils ([alpha]-bisabolol and chamazulene
); phenolic flavonoid compounds (apigenin, apigenin-7-O glycoside, luteolin, patuletin, and quercetin); mucilage; and coumarins.
Further on it was found that chamazulene
the main essential oil compound of German chamomile was relatively stable different under field conditions but oxygenated compounds (bisaboloids) were more influenced by delayed planting and ecological conditions (high temperature, long day period during flowering) (Mohammad et al., 2010).
The biocidal efficacy against different pathogens shown by various essential oils (EO) led us to study the Matricaria chamomilla EO and two of its main components (chamazulene
and [alpha]-bisabolol) against the [L.sub.3] larvae of Anisakis type I.
The essence (including: farnesene, chamazulene
, bisabolol, oxide of A & B).
