Octadecatrienoic Acid
An octadecatrienoic acid is a chemical compounds with formula , a polyunsaturated fatty acid with whose molecule has an 18-carbon unbranched backbone with three double bonds. The name refers to many different structural and conformational isomers, that differ in the position of the double bonds along the backbone and on whether they are in ''cis'' ('Z') or ''trans'' ('E') conformation. Some isomers have considerable biological, pharmaceutical, or industrial importance, such as: * α-Linolenic acid (9''Z'',12''Z'',15''Z''), found in many cooking oils * γ-Linolenic acid (6''Z'',9''Z'',12''Z''), found in the evening primrose (''Oenothera biennis'') * Pinolenic acid (5''Z'',9''Z'',12''Z''), found in the seeds of pines (''Pinus'' species) * Columbinic acid (5''E'',9''Z'',12''Z''), found in ''Thalictrum'' seed oils * α-Eleostearic acid (9''Z'',11''E'',13''E''), the main component of tung oil, produced from the nuts of tung tree (''Vernicia fordii'') * β-Eleostearic acid (9''E ...

Thalictrum
''Thalictrum'' () is a genus of 120-200 species of herbaceous perennial flowering plants in the buttercup family, Ranunculaceae, native mostly to temperate regions. Meadow-rue is a common name for plants in this genus. ''Thalictrum'' is a taxonomically difficult genus with poorly understood species boundaries; it is in need of further taxonomic and field research for clarification. Despite their common name of "meadow-rue", ''Thalictrum'' species are not closely related to the true rue (family Rutaceae), but resemble its members in having compound leaves twice or thrice divided. Description Meadow-rue leaves are alternate, bipinnately compound, and commonly glaucous blue-green in colour. The flowers are small and apetalous (no petals), but have numerous long stamens, often brightly white, yellow, pink or pale purple, and are produced in conspicuous dense inflorescences. In some species (e.g. '' T. chelidonii'', '' T. tuberosum''), the sepals are large, brightly coloured and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pot Marigold
''Calendula officinalis'', the pot marigold, common marigold, ruddles, Mary's gold or Scotch marigold, is a flowering plant in the daisy family Asteraceae. It is probably native to southern Europe, though its long history of cultivation makes its precise origin unknown, and it may possibly be of garden origin. It is also widely naturalised farther north in Europe (as far as southern England) and elsewhere in warm temperate regions of the world.''The New RHS Dictionary of Gardening'' 1: 462.Interactive Flora of NW Europe: ''Calendula officinalis'' eti.uva.nl The Latin '' |
Calendic Acid
Calendic acid (sometimes α-calendic acid) is an unsaturated fatty acid, named for the pot marigold (''Calendula officinalis''), from which it is obtained. It is chemically similar to the conjugated linoleic acids; laboratory work suggests it may have similar ''in vitro'' bioactivities. Biosynthesis Calendic acid is an omega-6 fatty acid. though not usually listed with this group. Calendic acid is synthesised in ''Calendula officinalis'' from linoleate by an unusual Δ12-oleate desaturase A fatty acid desaturase is an enzyme that removes two hydrogen atoms from a fatty acid, creating a carbon/carbon double bond. These desaturases are classified as: * Delta - indicating that the double bond is created at a fixed position from the ... (a FAD 2 variant) that converts the ''cis''-double bond at position 9 to a ''trans'',''trans''-conjugated double bond system. An ''all-trans'' beta isomer has been described. : Effects Calendic acid is the fatty acid responsible for the reductio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pomegranate
The pomegranate (''Punica granatum'') is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between tall. The pomegranate was originally described throughout the Mediterranean Basin, Mediterranean region. It was introduced into Spanish America in the late 16th century and into California by New Spain, Spanish settlers in 1769. The fruit is typically in season in the Southern Hemisphere from March to May, and in the Northern Hemisphere from September to February. As intact sarcotestas or juice, pomegranates are used in baking, cooking, juice blends, meal garnish (food), garnishes, smoothies, and alcoholic beverages, such as cocktails and wine. Pomegranates are widely cultivated throughout the Middle East and Caucasus region, North Africa, north and tropical Africa, Iran, Armenia, the Indian subcontinent, Central Asia, the drier parts of Southeast Asia, and the Mediterranean Basin.

Punicic Acid
Punicic acid (also called trichosanic acid) is a polyunsaturated fatty acid, 18:3 ''cis''-9, ''trans''-11, ''cis''-13. It is named for the pomegranate, (''Punica granatum''), and is obtained from pomegranate seed oil. It has also been found in the seed oils of snake gourd. Punicic acid is a conjugated linolenic acid or CLnA; i.e. it has three conjugated double bonds. It is chemically similar to the conjugated linoleic acids, or CLA, which have two. It has also been classified as an "n-5" or "omega-5" polyunsaturated fatty acid. In lab rats, punicic acid was converted to the CLA rumenic acid Rumenic acid, also known as bovinic acid, is a conjugated linoleic acid (CLA) found in the fat of ruminants and in dairy products. It is an omega-7 trans fatty acid. Its lipid shorthand name is cis-9, trans-11 18:2 acid. The name was proposed b ... (9Z11E-CLA).

Southern Catalpa
''Catalpa bignonioides'' is a species of ''Catalpa'' that is native to the southeastern United States in Alabama, Florida, Georgia, Louisiana, and Mississippi. Common names include southern catalpa, cigartree, and Indian-bean-tree (or Indian bean tree). It is commonly used as a garden and street tree. Description It is a medium-sized deciduous tree growing to tall, with a trunk up to diameter, with brown to gray bark, maturing into hard plates or ridges. The short thick trunk supports long and straggling branches which form a broad and irregular head. The roots are fibrous and branches are brittle, its juices are watery and bitter tasting. The leaves are large, bright green and heart shaped, being long and broad. They appear late, and as they are full-grown before the flower clusters open, they add much to the beauty of the blossoming tree. They secrete nectar, a most unusual characteristic for leaves, by means of groups of tiny glands in the axils of the primary veins. ...

Yellow Catalpa
''Catalpa ovata'', the yellow catalpa or Chinese catalpa (), is a pod-bearing tree native to China. Compared to ''C. speciosa'', it is much smaller, typically reaching heights between . The inflorescences form bunches of creamy white flowers with distinctly yellow tinging; individual flowers are about wide. They bloom in July and August. The leaves are very similar in shape to those of ''Paulownia tomentosa'', having three lobes (two are abruptly truncated on either edge, with a third, central, slightly acute, pointed lobe forming the leaf apex), and are darkly green. Fruits are very narrow, foot-long pods. Although native to the more temperate provinces within China (Anhui, Gansu, Hebei, Heilongjiang, Henan, Hubei, Jiangsu, Jilin, Liaoning, Nei Monggol, Ningxia, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan, Xinjiang), ''C. ovata'' is also cultivated in North America and Europe, and has become a parent of ''Catalpa × erubescens'' with the American species ''Catalpa bignonioide ...

Tung Tree
''Vernicia fordii'', usually known as the tung tree (, ''tóng'') is a species of flowering plant in the spurge family native to southern China, Myanmar, and northern Vietnam. It is a small to medium-sized deciduous tree growing to 20 m tall, with a spreading crown. The bark is smooth and thin, and bleeds latex if cut. The leaves are alternate, simple, 4.5–25 cm long and 3.5–22 cm broad, heart-shaped or with three shallow, maple-like lobes, green above and below, red conspicuous glands at the base of the leaf, and with a 5.5–26 cm long petiole. The flowers are 2.5–3.5 cm diameter, with five pale pink to purple petals with streaks of darker red or purple in the throat; it is monoecious with individual flowers either male or female, but produced together in the inflorescences. The flowers appear before or with the leaves in loose, terminal clusters. The fruit is a hard, woody pear-shaped berry 4–6 cm long and 3–5 cm diameter, containing ...

Tung Oil
Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree (''Vernicia fordii''). The oil and its use are believed to have originated in ancient China and appear in the writings of Confucius from about 400 BC. Tung oil hardens upon exposure to air (through polymerization), and the resulting coating is transparent and has a deep, almost wet look. Used mostly for finishing and protecting wood, after numerous coats, the finish can even look plastic-like. Related drying oils include linseed, safflower, poppy, and soybean oils. Raw tung oil tends to dry to a fine, wrinkled finish (the English name for this is gas checking); this property was used to make wrinkle finishes, usually by adding excess cobalt drier. To prevent wrinkling, the oil is heated to gas-proof it (also known as "boiled"). 'Tung oil' is often used by paint and varnish manufacturers as a generic name for any wood-finishing product that contains the real tung oil or provid ...
