Styrax benzoin tree

Benzoin, or gum benzoin, is a resinous secretion obtained from cuts made in the trunk or branches of the Styrax benzoin tree. It contains coniferyl benzoate, benzoic acid, benzyl cinnamate, vanillin (a phenol aldehyde) and a number of triterpenes. ... 

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... 

Benzoe Sumatra resinoid is obtained by solvent extraction of the resin from Styrax benzoin Dryand, a tree growing predominantly on the island of Sumatra. 

Benzoic acid in the free state, or in the form of simple derivatives such as salts, esters, and amides, is widely distributed in nature. Gum benzoin (from styrax benzoin) may contain as much as 20% benzoic acid in the free state or in combinations easily broken up by heating. Acaroid resin (from Xanthorrhoca hasHHs) contains from 4.5 to 7%. Smaller amounts of the free acid are found in natural products including the scent glands of the beaver, the bark of the black cherry tree, cranberries, prunes, ripe cloves, and oil of anise seed. Pem and Tolu balsams contain benzyl benzoate the latter contains free benzoic acid as well. The urine of herbivorous animals contains a small proportion of the glycine derivative of benzoic acid, hippuric acid [495-69-2], (C6H5CONHCH2COOH). So-called natural benzoic acid is not known to be available as an item of commerce. 

BENZOIN. The term benzoin is used in botany to denote a ircc (Styrax benzoin) and a resin obtained from it. The former is a tall, quick-grow ing tree native to Sumatra and Java. The tree has alternate entire leaves, the... 

Benzoe Sumatra resinoid is obtained by solvent extraction of the resin from Styrax benzoin Dryand., a tree growing predominantly on the island of Sumatra. Benzoe Sumatra resinoid is a dark brown, viscous liquid with a warm, powdery, sweet-balsamic odor. Its main volatile, odor-determining components are derivatives of benzoic and cinnamic acids and vanillin [284]. 

A balsamic resin, obtained from Styrax Benzoin by making incisions in the bark of the tree, and allowing the liquid... 

These are resinous mixtures that contain cinnamic and/or benzoic acid or their esters. Benzoin is a balsamic resin derived from the bark of Styrax benzoin (Styraceae) trees in Southeast Asia. Benzoin contains cinnamic, benzoic and triterpene acids. Its action is antiseptic, stimulant, expectorant, diuretic and antifungal. It is used as a food preservative and also as an ingredient in pharmaceutical preparations such as Whitfield s Ointment (with salicylic acid) for ringworm and athlete s foot (Tyler et al. 1988). 

G. Benzoe Resinoid E benjoin resinoide Two types of b. are commercially available, b. Siam and b. Sumatra. The Siam type is produced by hydrocarbon solvent extraction of the tree resin of Styrax tonkinensis, Styraceae, which grows wild in Thailand, Laos, Cambodia and Vietnam. A related tree, Styrax benzoin, gives the starting material for b. Sumatra. The resins are collected by making incisions in the tree bark and later collecting the accumulated sun-dried material. This raw...
