Main constituents and Phytochemicals of Purple Perilla.

Perilla Extract Perilla Ocymoides Extract EINECS ELINCS No.:290-151-0 CAS 90082-61-4 photo picture image Major Phytochemicals of Perilla oil: Pinene, Camphene, Myrcene, Limonene, Humulene, Caryophyllene, 3-Octanol, 1-Octen-3-ol, Linalool, Terpineol, 10-Pinanol, Perillyl alcohol, Phenylethyl alcohol, 10-Pinanal, Perillaldehyde, Benzaldehyde, Carvone, Linalool oxide,1-perillaldehyde;1-perilla-alcohol;elshottzia ketone.

 Perilla leaves contain about 0.2% of an essential oil, which varies widely in composition. Several different chemotypes are known: PA (see below) is the only is the only one of culinary value; the others are PK (main component perilla ketone, minor components isoegomaketone and perillene), EK (main component elsholzia ketone, minor component naginata ketone), PL (main component perillene, minor components citral, perilla ketone, isoegomaketone), PP (phenylpropanoids: myristicin, dillapiol, elemicin, safrole) and C (main component citral, minor components perillene, perilla ketone, isoegomaketone). There is also a type rich in rosefurane, which might have potential as a cheaper substitute for rose oil in perfumery.

 Perilla flowering plants:

 In the most frequently cultivated chemotype (PA), the main component is perillaldehyd (p-menthadien-1,8(9)-al(7), 75%) Its minor constituents are limonene (13%), linalool, Beta-caryophyllene, l-menthol, limonene, Alfa-pinene, perillene (2-methyl-5-(3-oxolanyl)-2-pentene) and elemicin. Perillaldehyd can cause skin allergies.
 The C type is a potentially interesting source of citral, a pleasantly lemon-scented material much used in the flavour and perfume industries; see lemon myrtle for more on lemony flavours and citral.
 The PP type may also gain importance as a source of simple phenylpropanoids in the pharmaceutical industry. The high myristicin content makes this plant considerably toxic.

 The dominating constituents of the remaining types are monoterpenoid furanes, often ketones. Some of these, e.g., isoegomaketone, are severe pneumotoxins that have caused fatal poisoning in cattle repeatedly. The PK type must be considered a toxic plant that has no use in kitchen.
 The oxime of perilla aldehyd (perillartin) is about 2000 times sweeter than sucrose; it is used as an artificial sweetener in China.

 Perilla seeds contain a drying oil (40%) with high content of multiply unsaturated fatty acids (60% alpha-linolenic acid, 15% both linoleic and oleic acid); their medicinal value is sometimes matter of great exaggeration.

 Lastly, perilla contains the pseudotannins and antioxidants typical for the mint family; see hyssop for details. The reddish-purple colour of some cultivars is caused by an anthocyan pigment called perillanin chloride.
