  "text": "Report individual aliphatic and triterpenic alcohols concentrations as mg/kg of fatty material and their sum as 'total aliphatic alcohol content'. The total content is the sum of C22, C24, C26 and C28.\nThe composition of each of the individual alcoholic compounds should be expressed to one decimal point.\nTotal sterol concentration should be expressed without any decimal point.\nCalculate the percentage of each individual sterol from the ratio of the relevant peak area to the total peak area for sterols:\nSterol x = A x Σ A × 100\nwhere:\nA x Peak area for sterol x.\nΣ A Total peak area for sterols.\nApparent β-sitosterol: Δ5,23-stigmastadienol + clerosterol + β-sitosterol + sitostanol + Δ5-avenasterol + Δ5,24-stigmastadienol.\nCalculate the percentage of erythrodiol and uvaol:\nErythrodiol + Uvaol = A Er + A Uv Σ A T × 100\nwhere:\nA Er Area of Erythrodiol in computing system counts.\nA Uv Area of Uvaol in computing system counts.\nΣ AT Sum area for sterol + erythrodiol + uvaol in computing system counts.\nBesides the calculation of relative percentage of single sterols and triterpenic dialcohols and the total concentration of sterols, the concentration of erythrodiol and of uvaol and their sum, in mg/kg of fatty material must be calculated, according the following expressions:\nErythrodiol = A Er × m s A s × m × 1000\nUvaol = A Uv × m s A s × m × 1000\nwhere:\nA Er Peak area of Erythrodiol, in computing system counts.\nA Uv Area of Uvaol in computing system counts.\nA s Area of the α-cholestanol peak, in computing system counts.\nm s Mass of added α-cholestanol, in milligrams.\nm Mass of the sample used for determination, in grams.",
