Quantitative determination of α -tocopherol and quality control studies in Sarcopoterium spinosum L

ABSTRACT: A quantitative determination of α-tocopherol inSarcopoterium spinosumL. extracts was carried out by TLC-densitometry and HPLC-UV method. The α-tocopherol content in S. spinosumwas established between 0.017210-0.023744 % (TLC-densitometry) and0.025966-0.037212 % (HPLC-UV). The highest amount ofα-tocopherol was obtained from aerial parts in fruiting period in both methods. In addition, contents of humidity, total ash andsulphated ash of plant samples were determined according to DAB 10
