| dc.description | The principal components of the hexane extract from olive leaves are analysed, following an analytical procedure based on the extraction with hexane and the later separation of groups of compounds, according to their polarity, by means of column and thin-layer chromatographies. The following components are separated and identified: hydrocarbons, ester waxes, triglycerides, tocopherols, esterols, lineal and terpenic alcohols and terpenic dialcohols. The olive leaves from five different varieties were analyzed: Picual, Arbequina, Hojiblanca, Empeltre and Cornicabra; the concentration of some compounds ranged between: 2.057-3.400 ppm saturated hydrocarbons; 38-152 ppm squalene; 915-1.874 ppm ester waxes; 28-100 ppm β-carotene; 832-1.396 ppm triglycerides; 41-125 ppm α-tocopherol; 614-2.500 ppm β-sitosterol; 95-311 ppm alcohols and 342-837 ppm terpenic dialcohols. | - |
| dc.description | Se analizan los principales componentes del extracto de hexano de hojas de olivo, siguiendo un esquema analítico basado en la extracción con hexano y posterior separación de grupos de compuestos, según su polaridad, mediante cromatografía en columna y en capa fina. Se separan e identifican los siguientes componentes: hidrocarburos, ceras ésteres, triglicéridos, tocoferoles, esteroles, alcoholes lineales y terpénicos y dialcoholes terpénicos. Se han estudiado las hojas de olivo de cinco variedades: Picual, Arbequina Hojiblanca, Empeltre y Cornicabra, los rangos del contenido, en ppm, de algunos compuestos resultaron: hidrocarburos saturados, 2.057-3.400; escualeno, 38-152; ceras ésteres, 915-1874; β -caroteno, 28-100; triglicéridos, 832-1.396; α -tocoferol, 41-125; β-sitosterol, 714-2.500 alcoholes totales 95-311 y dialcoholes terpénicos, 342-837. | - |
