Perillene
Perillene is a natural monoterpene that consists of a furan ring with a six-carbon homoprenyl side chain. Perillene is a component of the essential oil obtained by extraction of the leaves of ''Perilla frutescens''. Perillene has also been obtained by steam distillation of the leaves of ''Perilla frutescens''. Perillene has been found to elicit distinct electrophysiological responses in the antennae of the apple blossom weevil. It has been suggested that perillene is one several terpene hydrocarbons in the emanation bouquet of apple tree buds which may be used by adult weevils as chemical cues to discrimination during host-searching behavior. Applications Perillene, as an active ingredient of perilla oil, has been claimed to have anti-inflammatory and bactericidal action.Jiawen Yu, “Fingerprint identification of Perilla oil containing perillaldehyde and perillene with anti-inflammatory, intestinal motility promoting and bactericidal effects”, CN Patent 101,669,992 (2010) ...

Monoterpene
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids are diverse. They have relevance to the pharmaceutical, cosmetic, agricultural, and food industries. Biosynthesis Monoterpenes are derived biosynthetically from units of isopentenyl pyrophosphate, which is formed from acetyl-CoA via the intermediacy of mevalonic acid in the HMG-CoA reductase pathway. An alternative, unrelated biosynthesis pathway of IPP is known in some bacterial groups and the plastids of plants, the so-called MEP-(2-methyl-D-erythritol-4-phosphate) pathway, which is initiated from C5 sugars. In both pathways, IPP is isomerized to DMAPP by the enzyme isopentenyl pyrophosphate isomerase. Geranyl pyrophosphate is the precurso ...

Perilla Frutescens
''Perilla frutescens'', commonly called deulkkae, perilla or Korean perilla, is a species of ''Perilla'' in the mint family Lamiaceae. It is an annual plant native to Southeast Asia and Indian highlands, and is traditionally grown in the Korean peninsula, southern China, Japan and India as a crop. An edible plant, perilla is grown in gardens and attracts butterflies. It is aromatic with a strong mint-like smell. A variety of this plant, ''P. frutescens'' var. ''crispa'' known as "shiso", is widely grown in Japan. In the United States, perilla is a weed pest, toxic to cattle after ingestion. Names Along with other plants in the genus ''Perilla'', the plant is commonly called "perilla". It is also referred to as Korean perilla, due to its extensive cultivation in Korea and use in Korean cuisine. In the United States, where the plant has become a weed, the plant is known by many names, such as perilla mint, beefsteak plant, purple perilla, Chinese basil, wild basil, blueweed, ...

Apple Blossom Weevil
''Anthonomus pomorum'' or the apple blossom weevil is a univoltine herbivore of apple trees, ''Malus domestica An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ' ...''. Life history Adults generally overwinter in leaf litter of forests or hedgerows. In the spring, they emigrate to orchards and colonize apple trees. They may find their host trees using pheromones or plant-derived chemical cues. Spiders can be effective predators of ''A. pomorum''.Marc, P., and A. Canard. 1997.

Perilla Oil
Perilla oil ( ''Deulgireum'') is an edible vegetable oil derived from perilla seeds. Having a distinct nutty aroma and taste, the oil pressed from the toasted perilla seeds is used as a flavor enhancer, condiment, and cooking oil in Korean cuisine. The oil pressed from untoasted perilla seeds is used for non-culinary purposes. Production Perilla oil is obtained by pressing the seeds of perilla, which contains 38-45% lipids. Nutrition Perilla oil is considered a rich source of fatty acids, and contains both saturated and unsaturated fatty acids. Saturated fatty acids in perilla oil are mainly palmitic (5-7%) and stearic (1-3%). Monounsaturated fatty acids in perilla oil are oleic (12-22%), while polyunsaturated fatty acids in perilla oil are linoleic (13-20%), gamma-linolenic (0-1%), alpha-linolenic (54-64%), and arachidic (0-1%). In comparison to other plant oils, perilla oil exhibits one of the highest proportion of omega-3 fatty acids, which is between 54 and 64%. T ...

Perilla Ketone
Perilla ketone is a natural terpenoid that consists of a furan ring with a six-carbon side chain containing a ketone functional group. It is a colorless oil that is sensitive to oxygen, becoming colored upon standing. The ketone was identified in 1943 by Sebe as the main component of the essential oil of Perilla frutescens. Perilla ketone is present in the leaves and seeds of purple mint (''Perilla frutescens''), which is toxic to some animals. When cattle and horses consume purple mint when grazing in fields in which it grows, the perilla ketone causes pulmonary edema leading to a condition sometimes called perilla mint toxicosis. Synthesis Perilla ketone was synthesized in 1957 by Matsuura from 3-furoyl chloride and an organocadmium compound similar to the Gilman reagent made from an isoamyl Grignard reagent and cadmium chloride. Perilla ketone (3-Furyl isoamyl ketone) has been prepared in 74% yield via the Stille reaction from a 3-furyl-organotin compound and isocaproyl c ...
