According to Bacon1), Cinnamomum Mercadoi, Vid. is widely distributed in the Philippine islands. Calingag is the Tagaloc name of the tree. 25 kg. of the bark of a tree from the Lamao region, Bataan province, yielded after comminution 260 g. = 1,04 p. c. of a light yellow oil with an odor of sassafras; it had the following constants: d30/4o1,0461; aD30o + 4o; nD30o 1,5270. Neither bisulphite nor phenylhydrazine revealed the presence of aldehydes. Upon distillation under 10 mm. pressure the following fractions were obtained: fraction I (77 g.): b. p. 119 to 124°; nD30o1,5333; fraction II (9,2 g.): b. p. 124 to 130°; nD30o 1,5320; residue: 11,5g.; nD30o 1,5278. After distillation under ordinary pressure, fraction I had the following properties: b. p. 235 to 238° (760 mm.); d*f 1,0631; aD30o + 0,9o; nD30o1,5335. Oxidation with chromic acid yielded piperonylic acid, m. p. 227°. When heated with alcoholic potassa and subsequently oxidized with permanganate, piperonal resulted. This shows that the oil of this species of Cinnamomum contains much safrol.
