Investigations of a Possible Chemical Effect of Salvadora persica Chewing Sticks

Table 1

Chemical composition of S. persica roots essential oil and the amount of benzyl isothiocyanate, benzyl cyanide, and benzaldehyde in Miswak brushes.

Sample	Benzyl isothiocyanate	Benzyl cyanide	Benzaldehyde
Essential oil	74.42%	16.26%	0.67%
Amount of compounds in Miswak brushes (mg/g dry wt)
Miswak-0	6.49 ±	0.190 ±  0.	0.005 ±
Miswak-1	3.52 ±	0.129 ±	0.006 ±
Miswak-2	2.01 ±	0.072 ±	0.007 ±
Miswak-4	1.49 ±	0.037 ±	0.005 ±

Miswak-0 stands for baseline piece, that is, the amount of compounds present originally in the Miswak pieces. Miswak-1 stands for amount of compounds found in miswak brushes after one-time use; similarly Miswak-2 and Miswak-4 stand for amount of compounds in Miswak brushes after two- and four-time use. Different letters on values are indicating statistical difference () between values presented in the same column. Each value expressed in the table is a mean ± standard error ().
