Anethole sassafras

Determination of the phenols is of special importance in the analysis of hop (carvacrol), thyme, ajOwan (thymol), aniseed, badiana, fennel (anethole), clove bud and stem (eugenol) and sassafras oils (safrole). 

Upper Cross Street 10-11 People s Park Center Singapore 058358 TEL (65) 534-4220 FAX (65) 534-3076 Comments Sassafras oil and some aromatic chems such as vanillin, anethole and heliotropin. 

All the materials tested were effective with the exception of boronia (Figure 4). Eucalyptus induced a 93% mortality, while cypress gave 90%, camphor 83% (Figure 2[10]), spearmint 78%, white thyme 75%, pheasant grass 50%, sassafras 50%, anethole (Figure 2[11]) 35%, red thyme 34%, and aniseed 28% (P < 0.05). It is interesting to note the disparity between white thyme and red thyme which indicates that either there is a significant increase in one bioactive compound in one cultivar versus the other, or that a specific ratio of compounds in the mixture is more effective than another. 

Fig. 3A, B The major constituent of the essential oils 1-6 is detectable VS reagent as a red-violet to brown-violet zone at R, 0.9-0.95. In the essentia] oil of anise (1), staranise (2), bitter fennel (3) or. sweet fennel (4) it is anethole (Tl) with smaO amounts of the isomer methylchavicol, while basil (5) has predominantly methylchavicol which has the same R, value as anethole. The prominent zone of sassafras oil (6) is safrole (T2). Anethole (Tl) and safrole (T2) can be separated in the solvent toluene (see Fig. 4C), where safrole then shows a higher R, value.

Safrole, a- and j8-asarone, isosafrole, and anethole extracted from alcoholic beverages and essential oils (e.g., sassafras, nutmeg, and cinnamon) were baseline resolved on a C g column (A = 290nm, ex 325 run, emor310nm, ex 3SSnm, em) using a 45/55 acetonitrile/water mobile phase [1258]. Elution was complete in <10 min and a quantitation limit of 0.4ng/pL was reported.
