Investigation on Compositions of Seed Oil and Yield of Silymarin of Seeds from Silybum marianum (L.) Gaertn. Cultivated in Konya Ecological Conditions

Milk thistle (Silybum marianum (L.) Gaertn.) is an herbal supplement used to treat liver and biliary disorders. The active constituent of milk thistle is silymarin, a mixture of flavonolignans. It is also contains important faty oil acid ansaturated. In this study, researchs have been conducted in Medicinal – Aromatic Plants laboratory and Medicinal and Aromatic Pants Experimental Farm of Field Crops Department, Agriculture Faculty, Selcuk Universty. The aim was to determine the effect on yıeld and quality some characters of organic fertilizers applied at the different doses on milk thistle (S. marianum) cultivated under Konya (Turkey) ecolojical conditions. It were applied at the three different doses sheep manure as organic fertilizer. In this study; plant height, plant seed yield, yield of crude oil, composition and yield of oil and flavonoid (silymarin) were examined.

According to results of this research; plant height, seed yield, yield of crude and composition and yield of oil and flavonoid (silymarin) varied between 75–118cm, 720–1480kg/ha, 20–28% and % 1.1–3.1, respectively. In this research; high silymarine yield, crude oil yield, fatty acid composition and drug of milk thistle (S. marianum) cultivated in Konya ecological conditions were obtained from 15000kg/ha from applied organic fertilizer.
