beta-caryophyllene, muuroladinene, caryophyllene oxide, and mint sulphide from Cedrela odorata
Cedrela odorata (Meliaceae) Cigar-box cedar
Cedrela odorata, a member of the Mahogany family (Meliaceae), is a deciduous tree from Central- and South America reaching a height of 30 m. In spite of its popular name it has nothing to do with true cedar, which is a conifer. Cedrela is the classical source of wood used for making cigar-boxes. Its red-brown wood is aromatic, light, soft and not attacked by insects.
The waste-wood from producing cedrela boards and veneer can be steam-distilled to yield an essential oil of pleasant dry-woody odour with an undertone like carrot seed oil. However, Cedrela odorata is now under protection as a threatened species in several countries.
Cedrela contains the main sesquiterpenes formed from cis- and trans-farnesyl pyrophosphate. Beta-caryophyllene and cis-4(14),5-muuroladinene have been found to be the major sesquiterpenes in the oil distilled from cedrela stems, and caryophyllene oxide the major oxygenated sesquiterpene [180]. The rare sesquiterpenoid mint sulphide has been detected in cedrela leaf essential oil [181].
3-butylphthalide
3-butyl-4,5-
dihydrophthalide
Apium graveolens (Umbelliferae)
Cultivated forms of celery all descend from the wild type, Apium graveolens, growing in saline areas near the coastline in Europe and western Asia. Celery, A. g. var. dulce has long, thick and crispy stalks. Celery root, or celeriac, A. g. var. rapaceum, has a swollen, beet-like root with a mild taste. Celery seed oil is produced in France, India and California. It is used chiefly for flavoring foods, vegetable juices, etc., although small quantities are also used in perfumery.
The characteristic celery flavour is mainly caused by the two lactones 3-butylphthalide and 3-butyl-4,5-dihydrophthalide (sedanenolide) [6]. See also lovage.
methyl benzoate and (E,E)-alpha-farnesene
from champak headspace
Champak
Michelia (Magnolia) champaca (Magnoliaceae)
Champaca
The legendary champak, a member of the magnolia
family, is a native of the temperate Himalayan region. However, it is
now found distributed throughout tropical and subtropical Asia. In India,
where the flowers are collected for perfumery purpose, it is found in
eastern Himalayas and eastern and western Ghats. The trees bloom once
during the monsoon and again in spring. When fully in bloom, the trees
are covered with thousands of golden yellow flowers with a powerful and
diffusive fragrance. The ripe seeds are seen in the photo in the middle.
Rout, Naik and Rao analysed the headspace from the live flowers by solid
phase micro-extraction. Methyl benzoate, phenethyl alcohol, phenylacetonitrile,
indole and methyl anthranilate, along with sesquiterpenes, e.g. (E,E)-alpha-farnesene,
constituted the body of the headspace. Moreover, ionones, e.g. dihydro-beta-ionone,
(Z)-methyl-epi-jasmonate, a number of aromatic esters, etc., have been
identified in extracts from the flowers [136].
Champak absolute is used in high-class perfumes where it may produce a
unique, warm, floral-leafy note which is often compared to that of a fine
grade of tea. The famous perfume Joy (Jean Patou 1935), a costly floral
scent, was based on champak absolute and other floral absolutes. Today
the champak flower volatiles are gently extracted using supercritical
CO2. The extract has an intensely sweet, floral-fruity odor with an apricot-like
undertone.
Etymology: Michelia, after the Florentine botanist Pietro Antonio
Micheli (1679–1737). Hindi Tchampaca.
1-octene-3-ol
Agaricus campestris (Agaricaceae) Meadow mushroom
The pleasant, characteristic flavour of a freshly cut champignon is dominated by an alcohol called matsutake alcohol, because it was first identified in the Japanese matsutake mushroom, Tricholoma matsutake (Tricholomataceae). It is found in several mushrooms, and it is one of the odour components from mould. Matsutake alcohol is chemically 1-octene-3-ol [6].
This compound can be synthesized in a one-step reaction (Grignard) from pentylmagnesium bromide and acrolein.
