Extraction Of Silymarin Compounds From Milk Thistle (Silybum Marianum) Seed Using Hot, Liquid Water As The Solvent, J. F. Alvarez Barreto, D. Julie Carrier, E. C. Clausen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

High-value specialty chemicals are usually obtained from natural products by extracting with generally regarded as safe (GRAS) solvents. Because organic solvents are quite often used, high operating and disposal costs occur. When compared to traditional solvents, water is an interesting alternative because of its low operating and disposal costs. Milk thistle contains compounds (taxifolin, silychristin, silydianin, silybinin A, and silybinin B) that display hepatoxic protection properties. This paper examines the batch extraction of silymarin compounds from milk thistle seed meal in 50°C, 70°C, 85°C and 100°C water as a function of time. For taxifolin, silychristin, silybinin A, and silybinin B, …

Age Mediated Effects On The Alternative Respiratory Pathway In Leaves Of Rhodiola Rosea And Ajuga Reptans, Natalia V. Pystina, Roman A. Danilov

Turkish Journal of Botany

The influence of aging processes on respiration and the ratio of respiratory pathways in the leaves of Rhodiola rosea L. and Ajuga reptans L. under natural conditions was investigated. Young leaves had a higher respiration rate and higher activity of the alternative respiratory pathway than did mature leaves. The capacity of the alternative respiratory pathway did not show significant differences between the young and mature leaves of R. rosea and increased in the mature leaves of A. reptans (from 60% up to 88%). This fact may be explained by the higher requirements of growing tissues for metabolites. In this case, …
