Litsea cubeba (Lour.) Pers. (Litsea citrata BL, Laurus cubeba Lour., Daphnidium cubeba), or pokok myuniak kayah puteh (Malay, Indonesian), is a shrub which grows wild in China, Korea, Vietnam, and Indonesia. The stems are smooth the leaves are aromatic, simple, and exstipulate. The petiole is about 1 cm long. The blade is lanceolate, thinly coriaceous, 12—4 cm X 3-1 cm and shows six to eight pairs of secondary nerves. The fruits are globose and 3 mm in diameter (Fig. 26). [Pg.57]

The plant is strongly aromatic on account of an essential oil which comprises cis-a-ocimene (25.11%), 3,7-dimethyl-l,6-octadien-3 ol (16.85%), and trans-nerolidol (13.89%), hence the use of the plant in aromatherapy. A methanolic extract of bark of Litsea cubeba (Lour.) Pers. and its fractions (0.01 mg/mL) from bark inhibit NO and PGE2 production in LPS-activated RAW 264.7 macrophages without significant cytotoxicity at less than 0.01 mg/mL concentration. The methanol extract decreased the enzymatic activity of myeloperoxidase (0.05 mg/mL). These findings suggest that L. cubeba is beneficial for inflammatory conditions and may contain compound(s) with anti-inflammatory properties (63). Can we expect the vasorelaxant laurotetanine (64) isolated from the plant to exert such activity ... [Pg.58]

Isolation from Essential Oils. Citral is isolated by distillation from lemongrass oil and from Litsea cubeba oil. It is the main component of these oils. [Pg.37]

Individual compounds can be isolated from essential oils containing one or only a few major components by distillation or crystallization. Examples are eugenol from clove oil, menthol from commint oil, citronellal from Eucalyptus citriodora oil and citral from Litsea cubeba oil. These compounds are used as such or serve as starting materials for the synthesis of derivatives, which are also used as flavor and fragrance substances. However, the importance of some of these oils has decreased substantially because of the development of selective synthetic processes for their components. [Pg.169]

The two oils were formerly the main source of natural citral, obtained as a ca. 4 1 mixture of geranial and neral by distillation [463, 466a]. However, lemongrass oil has declined in commercial importance due to the competitive synthesis of citral and isolation of natural citral from Litsea cubeba oil. Today, some lOOt/yr are still...

Litsea cubeba oil is produced by steam distillation of the fruits of Litsea cubeba C. H. Persoon (Lauraceae) growing in East Asia. It is a pale yellow liquid with a fresh odor, reminiscent of citral. [Pg.203]

Citral is a mixture of the cis- and trans-isomer aldehydes geranial and neral, which are very important as widespread components in various flavours. The origin assignment to the main natural sources, Litsea cubeba oil and lemon grass oil, respectively, can easily be performed, because lemon grass (Cymbopogon citratus) is a C4-plant, providing 8 C-values of about -12%c, whereas 8 C-values around -26%o are expected...
