Cyclopentane bicyclic monoterpenoids that occur in the plant kingdom belong to three major skeletal types camphane, iso-camphane, and fenchane (Fig. 7). Camphane-type terpenoid alcohols, (+)-bomeol (Gl) and (—)-isobomeol (G2), have been isolated from Cinnamomum camphora (Lauraceae) and Achillea filipendulina (Asteraceae). A ketone derived from these, (-h)-camphor (G3), is found in the camphor tree Cinnamomum camphora) and in the leaves of rosemary Rosmarinus officinalis) and sage Salvia officinalis, Labiatae). Camphene (G4) and its enantiomer with the isocamphane carbon skeleton are known to occur in the oils of citronella and turpentine. Fenchane-type bicyclic cyclopentane monoterpenoids are commonly found in plants as their ketone derivatives. (—)-Fenchone (G5) occurs in the tree of life Thuja occidentalis, Cupres-saceae). Its enantiomer, (+)-fenchone (G6), has been isolated from the oil of fennel Foeniculum vulgare, Umbelliferae). 

Naturally occurring camphanes include the bomeols with an endo hydroxy group, the isobomeols with an exo OH and 2-camphanone (2-bonanone) referred to as camphor. (+)-Bomeol from the camphor tree Cinnamomum camphora (Lauraceae) and from the roots of ginger-like Curcuma aromatica (Zingiberaceae), both of which grow in Eastern Asia, is known as Borneo camphor. (-)-Isobomeol was isolated from Achillea filipendulina (Asteraceae). 

From the biogenetic point of view, the most important tetrahydrobenzylisoquinoline alkaloids is undoubtedly (+ )-reticuline (20). This alkaloid is the precursor of a number of more elaborate compounds (Fig. 32.6) and is widely distributed. (+ )-Reticuline is first synthesized and then converted to (- )-reticuline (21) in the plant (Fig. 32.8) (Bat-tersby and Foulkes, 1965 Beecher and Kellelior, 1988). Reticuline occurs in the ( + )-form in Annona reticulata (An-nonaceae), Cinnamomum camphora (Lauraceae), and in... 

An important precursor of (-)-perrillyl aldehyde (periUal) is (-)-perillyl alcohol. Fenchol (also known as a-fenchyl alcohol or fenchan-2-ol, 8-20) is a bicyclic monoterpenic alcohol occurring as a minor component in citrus, fennel and sage essential oils. Another common compound is the bicyclic alcohol thujan-4-ol (sabinene hydrate), which occurs at a high level in the marjoram essential oil (see Table 8.32, later). Borneol (bornan-2-ol) is a component of camphor oils Cinnamomum camphora, Lauraceae). Trivial and systematic names of selected monoterpenic alcohols are listed in Table 8.6. 

Bicyclic ketone camphor, formed by oxidation of borneol, is a component of cinnamon, sage and rosemary essential oils. In nature, camphor is formed by the oxidation of borneol, and usually occurs as a mixture of two isomers, (+)-camphor (8-51), which is more common, and (-)-camphor (8-51). Camphor is obtained from the camphor laurel tree wood Camphor officinalis, syn. Cinnamomum camphora, Lauraceae) originating in Indochina, where it grows in large numbers. A further sesquiterpenic ketone is (-)-fenchone (8-51), which is found in many essential oils, for example in fennel essential oil.

Camphor oil is obtained by steam distillation of the wood of the camphor tree Cinnamomum camphora Sieb. (Lauraceae) growing in China, Taiwan, and Japan. The main constituent of the crude oil is camphor (ca. 50%), which can be separated by crystallization on cooling and subsequent centrifugation. Fractionation of the mother liquor gives two oils ... 

CAMPHOR The drug from the essential oil, obtained by steam distillation of the wood from Cinnamomum camphora (L.), J.Presl, belonging to the family Lauraceae, a high tree that is cultivated mainly in Taiwan. The production of natural camphor (optically active) has been replaced by synthetic camphor (racemate), which is synthesized from a-pinene (from turpentine oil).

L-( + )-ReticuIine, C19H23NO4 (LI), was first isolated from Annona reticulata Linn. (Annonaceae) by Gopinath et al. (9S). It has also been found in Cinnamomum camphora (Linn.) Sieb. (Lauraceae) (99), in hylica rogersii Pillans (Rhamnaceae) (100), in opium (101), and in Thailand Joss pow der, a product presumably reduced from plants of the Machilus genus (65). Racemic reticuline has been isolated from opium and from the mother liquors of the purification of morphine (102). 

Cinnamomum aromaticum Nees (Lauraceae) proved to be a contact insecticide to T. castaneum and S. zeamais (Huang and Ho, 1998). C. cassia and C. sieboldii proved to have pesticidal action against S. oryzae and Callosobruchus chinensis (Kim et al., 2003b). Cinnamaldehyde causes acaricidal effects on T. putrescentiae, especially in closed containers (Kim et al., 2004). C. camphora (L.) J. Presl causes mortality to D. gallinae and can be used as acaricide against them (Kim et al., 2007).
