... After iv injection of 0.1 mL/kg, death due to massive pulmonary edema occurred within minutes. In this animal blood and tissue levels of alpha-terpineol of between 150 and 300 ppm were observed. After smaller doses of pine oil (0.033 mL/kg), horses survived until euthanized up to 48 hr later. Blood levels of alpha-terpineol became undetectable in one of these animals after 2 hr, and no tissue levels were detected at postmortem....

The metabolic fate of alpha-terpineol administered orally to male albino-rats was investigated, and its effects on the liver microsomal cytochrome-P-450 system were studied. For metabolic studies, alpha-terpineol was given once daily for 20 days at a dose of 600mg/kg bw; cytochrome-P-450 studies involved dosing for up to 9 days. ...The neutral fraction isolated showed the presence of one major (alpha-terpineol) and two minor compounds. One of the minor compounds was identified as p-menthane-1,2,8-triol. Further study revealed the presence of the methyl esters of oleuropeic-acid and dihydrooleuropeic-acid. Allylic oxidation of C-1 methyl esters appeared to be the major metabolic pathway. It was considered likely that the allylic methyl group at C-7 was oxidized prior to the reduction of the 1,2-double bond. Administration of alpha-terpineol increased the levels of liver microsomal cytochrome-P-450 by 72, 104, 90, 54, and 52% after 1, 2, 3, 6, and 9 days of dosing, respectively. A moderate incr was noted in the levels of liver microsomal NADPH-cytochrome-c-reductase during the first 3 days of repeated dosing. No significant effect was noted on cytochrome-b5 and NADH-cytochrome-c-reductase. The authors conclude that the allylic methyl oxidation of alpha-terpineol is the major route for its metabolic transformation in the rat. The reduction of the endocyclic double bond was specifically noted in the formation of dihydrooleuropeic-acid from oleuropeic-acid.

Biotransformation of alpha-terpineol by the common cutworm (Spodoptera litura) larvae was investigated. alpha-Terpineol was mixed in an artificial diet, and the diet was fed to the larvae (fourth-fifth instar) of S. litura. Metabolites were isolated from the frass and analyzed spectroscopically. Main metabolites were 7-hydroxy-alpha-terpineol (p-menth-1-ene-7,8-diol) and oleuropeic acid (8-hydroxy-p-menth-1-en-7-oic acid). Intestinal bacteria from the frass of larvae did not participate in the metabolism of alpha-terpineol. alpha-Terpineol was preferentially oxidized at the C-7 position (allylic methyl group) by S. litura larvae.

Details of the metabolism of alpha-terpineol by Pseudomonas incognita are presented. Degradation of alpha-terpineol by this organism resulted in the formation of a number of acidic and neutral metabolites. Among the acidic metabolites, beta-isopropyl pimelic acid, 1-hydroxy-4-isopropenyl-cyclohexane-1-carboxylic acid, 8-hydroxycumic acid, oleuropeic acid, cumic acid, and p-isopropenyl benzoic acid have been identified. Neutral metabolites identified were limonene, p-cymene-8-ol, 2-hydroxycineole, and uroterpenol. ... /I/t appears that P. incognita degrades alpha-terpineol by at least three different routes. While one of the pathways seems to operate via oleuropeic acid, a second may be initiated through the aromatization of alpha-terpineol. The third pathway may involve the formation of limonene from alpha-terpineol and its further metabolism.

In a minor pathway, the endocyclic alkene of alpha-terpineol is epoxidized and then hydrolysed to yield a triol metabolite 1,2,8-trihydroxy- para-menthane, which was also reported in humans after inadvertent oral ingestion of a pine-oil disinfectant containing alpha-terpineol.

Metabolized primarily by conjugation with glucuronic acid and excreted in urine. Oxidation of the allylic methyl group followed by hydrogenation to yield the corresponding saturated acid may occur.
