Vanillin, CgHgOj, is one of the most important synthetic perfumes. It is the active odorous ingredient of the vanilla pod, in which it occurs to the extent of about 2 per cent., appearing on the surface of the bean as a fine white crystalline efflorescence. It occurs naturally also in Sumatra benzoin (about 1 per cent.), Siam benzoin (15 per cent.), and the balsams of Tolu and Peru (traces). Numerous other bodies have been recorded as containing it, such as asafoetida, beetroot and asparagus, the seeds of Lupinus albus, the seeds of Sosa canina, etc. [Pg.198]

Inspection in long wave UV light (Fig. 109) provides further characterisation information. Siam or Sumatra benzoins or their tinctures may in practice be clearly differentiated in this way [66, 155]. [Pg.250]

Benzoin is the balsamic resin obtained from the bark of various Styrax spp. Styrax benzoin Dryand and 5. paralleloneurum Perkins yield Sumatra benzoin 5. tonkinensis (Pierre) Craib ex Hartwich and other related Styrax species yield Siam benzoin. [Pg.90]

The major constituents of Sumatra benzoin are p-coumaryl cinnamate, cinnamic acid, cinnamyl cinnamate (styracin), p-coumaryl benzoate, pinoresinol, benzoic acid, coniferyl cinnamate, and coniferyl benzoate. The major constituents of Siam benzoin are p-coumaryl benzoate, benzoic acid, pinoresinol, cinnamic... [Pg.90]

Both Siam benzoin and Sumatra benzoin are offlcial in pharmacopoeias of many countries however, only Sumatra benzoin is found in the BP. Both types are official in U.S.P., but in the United States Sumatra benzoin is more customarily used in pharmaceutical preparations. [Pg.90]

Siam benzoin contains no cinnamic acid and is almost entirely soluble in 90 per cent ethanol. It is included in the U.S.P. and the limits for benzoin under that authority include a minimum of 75 per cent alcohol-soluble extractive for Sumatra benzoin and 90 per cent for Siam benzoin. The U S,P, assay for alcohol-soluble extract is taken from the method of Bennett and Bickford. ... [Pg.126]

Acid value 105 to 163 (see Tolu Balsam), ester value 47 to 83, saponification value 169 to 223 (all calculated on dry alcohol-soluble matter) were standards in the B.P. 1948 but are not now official requirements. In the opinion of Parry these acid and ester values, which are to be determined on the sample, but calculated to the alcohol-soluble matter, will certainly exclude many pure samples of Sumatra benzoin. [Pg.126]

BENZOIN, GUM BENZOIN, or BENZOIN RESIN is a mixed balsam and resin. SIAM BENZOIN comes from Siam and nearby countries and is from the Styrax benzoin tree. It is of higher quality and usually lighter color than that from other sources. SUMATRA BENZOIN is from Sumatra, Java, and vicinity and is from other varieties of Styrax. It is definitely inferior and sells for much less than the Siam grade. Benzoin enters the market... [Pg.248]
