“…However, application of ultrasonic treatments alters the seed oil composition and decreased it to 60%. Results were in accordance with (Nasrollahi et al, 2016;Meddeb et al, 2017) Accelerated aging was also influenced seed oil composition of Milk thistle (Table 2) and linoleic content was declined as the aging progress. Similar results was reported about reduction of linoleic and oleic acid content of wheat fatty acid composition due to accelerated aging treatment (Ouzouline et al, 2009).…”

Milk thistle is a medicinal plant with high pharmaceutical properties to help relief of liver diseases. In this study, the effects of ultrasonic assisted seeds priming (20, 40, 80 and 160 s) with a frequency of 24 kHz and Power of 400 W was investigated on seed enhancement of aged seeds of Milk thistle. Results of the study, showed that as the aging damages increased, the longer sonication results in the better germination. Root growth was significantly improved using ultrasonic energy. Seeds aged for 24 hours, were exposed to ultrasonic produced for 20 seconds exhibited root length of 10.39 cm which was 5.48 cm with no ultrasonic treatment with the same aging duration. The maximum malondialdehyde activity was observed at the 96-hour aging treatment (87.83 nmol/grFW) while the lowest activity was observed at no aged and 24-hour aged seeds (7.28 nmol/grFW). It is suggested that there is a negative correlation between seedling vigor and MAD activity. It was revealed that fatty acid composition of Silybum marianum seed oil is highly influenced by the aging treatment. The variations of unsaturated fatty acids significantly increased in aged seeds. Our results showed that under accelerated aging conditions, ultrasonic assisted seed priming could not provide satisfactory enhancement to seed germination while no aged seeds germination was significantly improved using ultrasonic assisted seed priming.

“…In study by Iman Nasrollah 27 ; fatty acid compositions were studied in 4 different milk thistle oil; and palmitic acid (16:0) was respectively found as 8.55%, 8.36%, 7.99% and 9.26%; stearic acid (18:0) as 5.609%, 7.72%, 5.607% and 5.01%; oleic acid (18:1) as 28.68%, 35.85%, 28.54%, and 30.42%, while linoleic acid (18:2) was found as 54.5%, 43.57%, 54.71%, and 52.78% and finally linolenic acid (18:3) as 2.50%, 4.48%, 3.13% and 2.51%.…”

In this study, the compounds that contain active ingredients beneficial for health and disposed from t he fruits of milk thistle which from oil was extracted after cold press was obtained, and end products were provided.At this stage, total ash, insoluble ash in HCl, loss on drying, foreign matter, heavy metal and microbiology analyses were carried out on the milk thistle waste supplied as seeds. The seeds were treated to cold press, then oil and waste were obtained. Peroxide value, FFA, refractive index, fatty acid composition, saponification and iodine number were investigated in the oil. The waste had silymarin compounds significantly, therefore verification was performed for the quantitation of silymarin active ingredient in the waste. The waste contained up to 2% silymarin.As a result, a formulation was created for the standardized active ingredient and milk thistle oil, and end product was provided in the form of soft capsule.

Milk thistle seeds are a unique source of biologically active substances. The oilseed crop studied is used in various fields, both for food purposes, animal husbandry and in medicine. The characteristics of milk thistle oil were considered in the work. Milk thistle seeds are known to contain 35% vegetable oil (seed fat). The oil was obtained with cold pressing. Milk thistle seed oil was chosen as the object of study. Using an experimental extruder, the oil was obtained under the following modes: the annular gap of the grain chamber - 1.25 mm, the screw rotation speed - 190 rpm, the pressing temperature - 353 K. A comparative study of the fatty acid composition of milk thistle oil components with literary sources was carried out. Gas-liquid chromatography on a Chromotek 5000 device was used to determine the composition of the components according to the GOST 31665-2012 method. The calculation for the components of milk thistle oil on the basis of which the chromatograms were obtained for the amount of fatty acids was made. It was found out that the characteristics of the test sample are comparable with the literature data, but they also have differences, since other fatty acids were found in the oil. 24 fatty acids were identified by gas chromatographic analysis. The following ratio of fatty acids was determined: linoleic - 53%, oleic - 26%, palmitic - 8%, stearic (5%), arachidic (3%) and behenic (2%). The sample under study contains saturated and unsaturated fatty acids. According to the results of the vitamin composition analysis milk thistle oil contains vitamins A, E and K and minor β-carotene traces which are a valuable source for diet and preventive nutrition.
