![]() ![]() The bioactive compounds of the Colchicum species, especially tropolone alkaloids, flavonoids, and phenolic acids, have anti-inflammatory and anti-arthritic activities. Moreover, the corms of some species have nutritive value due to high starch and low alkaloid contents ( 3).įurthermore, these species also contain other compounds like isoquinoline alkaloids with anticholinesterase inhibitory activities, coumaric acid, ferulic acid, caffeic acid, vanillic acid, 2-hydroxybenzoic acid, apigenin, luteolin, and 4,6-dimethoxy-3,7- ( 4). These compounds, with potential valuable biological activities, have high potential toxicity and a narrow therapeutic index. Moreover, colchicine, demecolcine, and colchicoside are the main tropolone alkaloids of the Colchicum, which contain antitubullin activities and tubulin polymerization inhibitory effects. Tropolone alkaloids, as the main important bioactive compounds isolated from Colchicum species, are used for the treatment of diseases like gout and cancers. The Colchicum species and other plants of the Colchicaceae family have important bioactive compounds, including alkaloids, especially tropolone alkaloids and isoquinoline alkaloids, phenolic compounds, tannins, flavonoids, and carbohydrates, which their amount depends on the growing cycles and seasons ( 1, 2). Pharmaceutical characteristics of Colchicum are mainly derived from its corns and seeds. The Colchicum species, also known as “Sorenjân”, are important medicinal plants, which have been used for many diseases like osteoarthritis, gout, cancer, inflammations, jaundice, and sexual impotence in different societies. In addition, the morphological characterizations of this genus are the bulb-like corms and underground ovaries ( 1, 2). The genus Colchicum from the Colchicaceae family is a perennial monocotyledon flowering plant with more than 160 species, which are mostly grown in full sunny plains of western regions of Asia, Europe, and east and South of Africa. Total Alkaloid Phytochemicals Colchicine Chromatography Flavonoid 1. Moreover, the valuable biological effects of these plants stimulate the cultivations on a large scale. Always popular.This study demonstrated that the corm of the Colchicum species contained similar main compounds with different amounts, as well as appropriate physicochemical properties.
