DETERMINATION OF SAFROLE CONTENT OF SASSAFRAS OILS

13. DETERMINATION OF SAFROLE CONTENT OF SASSAFRAS OILS

The congealing point of sassafras oils gives a good estimate of the safrole content.

Procedure: Determine the congealing point of the sassafras oil (see p. 253 for details), and estimate the safrole content from Table 4.18.

 TABLE 4.18. CONGEALING POINT AND SAFROLE CONTENT

Table 4.18¹⁷³ will give values of the safrole content with an accuracy of about 2 per cent if the congealing point is above 2.

173 This table was prepared by the laboratories of Fritzsche Brothers, Inc.; it is based on the congealing points of known mixtures of safrole and pinene and safrole and eugenol.
