Aromatic plant products

Franz. Ch.. 1989b. Good agricultural practice (GAP) for medicinal and aromatic plant production. ActaHort., 249 125-128. [Pg.80]

Polymers derived from renewable resources can be broadly classified according to the method of production. A first category encompasses polymers directly extracted/removed from plants such as carbohydrates, aromatic plant products, polyisoprenes, and proteins. [Pg.190]

Lignin. Although aromatic amino acids are ubiquitous and are essential as food components, in sheer amount, lignin takes first place among the aromatic plant products. [Pg.292]

Arcmatic compounds phenols, phenolic acids, cinnamic acid derivatives, coumarins, flavonoids, quinones, and tannins, all of which are aromatic compounds, comprise the largest group of secondary plant products. They are often referred to as "phenolics" and have been identified as allelopathic agents in more instances than all of the other classes of compounds combined 5). [Pg.38]

Many herbicides and other chemicals have been reported to influence levels of various phenolic compounds in higher plants by unknown mechanisms. It is unlikely that more than a few of these compounds have a primary influence on secondary phenolic compound synthesis. For instance, in our survey of the effects of 17 herbicides on anthocyanin accumulation, only glyphosate appeared to directly influence accumulation (31). The effects of several compounds on secondary phenolic compound production for which the mechanism of influence is unknown are summarized in Table II. A much longer list could be derived from the literature. Unfortunately, many of these compounds are phytotoxic or are known to have effects other than on secondary aromatic compound production. In most cases the effects on these compounds correlate well with extractable PAL activity (31, 71, 72, 73, 74) (Figure 5), even though they do not directly affect the enzyme. [Pg.123]

Homestead agroforestry system provides nearly 50% cash flow to the rural poor (Ahmed 1999). Collectively, homestead agroforestry production system contributes about 70% fruit, 40% vegetable, 70% timber, and 90% firewood and bamboo requirement of Bangladesh (Miah and Ahmed 2003). In addition, the homestead plantations are recognized repositories of non-timber products such as medicinal and aromatic plants, ornamentals, bamboos, khair, lac, honey, cane, murta plants, and grasses. [Pg.439]

Shikimates, which include phenylalanine, tyrosine, tryptophan, and their derivatives, are represented by many aromatic natural products, including hydroquinones found inbrownalgae such as Sargassum (Segawaand Shirahama 1987). Flavonoids are a structural class of shikimates found in plants, including isoflavonoids or neo-flavonoids, as is the y-pyrone (coumarin) core structure (Knaggs 2003). [Pg.12]

Essential oils occur mainly in aromatic plants. A few of them are found in animal sources, e.g. musk, civet and sperm whale, or are produced by microorganisms [1, 3, 6, 23, 25, 26, 29-33]. The Council of Europe describes essential oil as a product obtained from vegetable raw material [27]. Owing to a ban on animal-based flavour and fragrance materials, essential oils of trade are entirely of plant origin... [Pg.44]

Bacteria and fungi play an essential role in the biosphere by breaking down the many aromatic products of plant metabolism.150 153 These include vast amounts of lignin, alkaloids, flavonoid compounds, and other biochemically "inert" substances. Lignin is a major constituent of wood and a plant product second only to cellulose in abundance. [Pg.1434]

Some of the pathways of animal and bacterial metabolism of aromatic amino acids also are used in plants. However, quantitatively more important are the reactions of the phenylpropanoid pathway,173-1743 which is initiated by phenylalanine ammonia-lyase (Eq. 14-45).175 As is shown at the top of Fig. 25-8, the initial product from phenylalanine is trails-cinnam-ate. After hydroxylation to 4-hydroxycinnamate (p-coumarate) and conversion to a coenzyme A ester,1753 the resulting p-coumaryl-CoA is converted into mono-, di-, and trihydroxy derivatives including anthocyanins (Box 21-E) and other flavonoid compounds.176 The dihydroxy and trihydroxy methylated products are the starting materials for formation of lignins and for a large series of other plant products, many of which impart characteristic fragrances. Some of these are illustrated in Fig. 25-8. [Pg.1438]
