Ouratea fieldingiana (Gardner) Engl is popularly used for wound healing. joseph joseph laundry basket dupe. This chapter focuses mainly on the classification of these compounds, their biosynthesis in plants and role in human health. Terpenoids. Plants can synthesize several organic compounds called secondary metabolites either during normal metabolic processes or in regarding to certain environmental conditions including wounds, temperature, UV-radiation, infection, and others (Cheynier, 2012; Tiago et al., 2017).These metabolites are grouped into different clusters in relative to the occurrence of Alkaloids and sulphur-containing compounds. Phenolic compounds are a large class of plant secondary metabolites, widely distributed in various higher plant organs such as vegetables, 1 fruits, 2,3 spices, 4 grains, 5 legumes, and nuts, 6 playing important roles in diverse physiological processes such as plant quality, coloring, flavor, and stress resistance. The plant phenolic compounds Phenolics can be classified into 2 groups: 1. Phenolic compounds are secondary metabolites in plants with a common aromatic ring bearing one or more hydroxyl groups [].More than 8000 natural phenolic compounds have been identified to date [].Phenolic compounds isolated from plant sources include simple phenols, flavonoids, lignins and lignans, tannins, xanthones, and coumarins [].These phenolic Native to the northern temperate regions, 430 different species are classified under Prunus. phenolic compounds structures, there are only two main pathways of their biosynthesis shikimic and acetate-malonate.
