The less common (-)-isomer has a piny, turpentine-like odor, and is found in the edible parts of such plants as caraway, dill, and bergamot orange plants. [3] Limonene takes its name from Italian limone ("lemon"). [4] Limonene is a chiral molecule, and biological sources produce one enantiomer: the principal industrial source, citrus fruit ...
Perillyl alcohol and its precursor limonene are naturally occurring monocyclic terpenes derived from the mevalonate pathway in plants. Perillyl alcohol can be found in the essential oils of various plants, such as lavender, lemongrass, sage, and peppermint. [1] It has a number of manufacturing, household, and medical applications.
In plants, VirA is a protein histidine kinase which senses certain sugars and phenolic compounds. These compounds are typically found from wounded plants, and as a result VirA is used by Agrobacterium tumefaciens to locate potential host organisms for infection. [95]
The constituents include phellandrene, limonene, elemol, elemicin, terpineol, carvone, and terpinolene. The seed kernels are used for food, both raw and cooked. An edible oil can be extracted from the seeds, and the pulp can be stewed but is somewhat insipid. The young shoots can be boiled and eaten as a vegetable. [3]
Many monoterpenes are volatile compounds and some of them are well-known fragrants found in the essential oils of many plants. [12] For example, camphor, citral, citronellol, geraniol, grapefruit mercaptan, eucalyptol, ocimene, myrcene, limonene, linalool, menthol, camphene and pinenes are used in perfumes and cosmetic products.
Carvone may be synthetically prepared from limonene by first treating limonene nitrosyl chloride. Heating this nitroso compound gives carvoxime. Treating carvoxime with oxalic acid yields carvone. [14] This procedure affords R-(−)-carvone from R-(+)-limonene. The major use of d-limonene is as a precursor to S-(+)-carvone. The large scale ...

Found in lowland subtropical rainforest and dry rainforest areas of Queensland and New South Wales, Australia. Early settlers consumed the fruit and retained the trees when clearing for agriculture. Commercial uses include boutique marmalade and restaurant dishes, and is exported for such. Finger lime: Citrus australasica
