This species is very abundant in the forests of Luzon and is 

 also found in Marinduque, Ticao, Mindoro, and Masbate.

PAGSAHINGIN RESIN 



This species yields a resin known locally as sahing. 



It is used locally for fuel and light and in some cases as caulk- 

 ing material for bancas. 



Bacon * examined the oil obtained from this resin and found 

 that it consisted principally of paracymol. In a later publica- 

 tion Bacon f gives the results of further investigation : 



In November, 1909, 3.5 kilos of resin were collected from one tree near 

 Lamao, Bataan Province. The volatile oil was distilled from the resin 

 in vacuo (4 to 6 millimeters) giving a total of 390 grams of oil (about 11 

 per cent). The latter had an odor like that obtained during a similar 

 distillation of Manila elemi (C. luzonicum A. Gray), and the aqueous 

 portion of the distillate contained a considerable amount of formic acid, 

 although there were no visible evidences of decomposition of the resin 

 during the distillation in vacuo. The oil was then distilled six times over 

 sodium, using a column of glass beads in the neck of the distilling flask, 

 and gave the following fractions: 



The residue was a thick, brown, viscous oil, which was attacked by 

 sodium when an attempt was made to distill it over that metal. 



Fraction No. 1 had a strong odor of pinene, and Nos. 1, 2, and 3 each
