5 Pharmacology and Biochemistry

5.1 Absorption, Distribution and Excretion

CARVACROL APPEARS TO BE SLOWLY ABSORBED FROM INTESTINE IN RABBIT, SINCE 22 HR AFTER ADMIN OF 1.5 G, SOME 30% WAS STILL IN GASTRO-INTESTINAL TRACT, ABOUT 25% OF DOSE HAVING BEEN EXCRETED IN URINE.

OPDYKE DL J; MONOGRAPHS ON FRAGRANCE RAW MATERIALS. CARVACROL; FOOD COSMET TOXICOL 17 (SUPPL) 743 (1979)

CARVACROL APPLIED TO INTACT SHAVED ABDOMINAL SKIN OF MOUSE WAS NOT ABSORBED WITHIN 2 HR.

5.2 Metabolism/Metabolites

/WHEN FED TO RABBITS,/ THE SUBSTITUTED MONOPHENOLS, THYMOL & CARVACROL, WHICH OCCUR IN ESSENTIAL OILS OF PLANTS...ARE...CONJUGATED WITH GLUCURONIC ACID & SULFATE.

Parke, D. V. The Biochemistry of Foreign Compounds. Oxford: Pergamon Press, 1968., p. 147

CARVACROL IS METABOLIZED BY CONJUGATION WITH GLUCURONIC ACID & SULFATE.

OPDYKE DL J; MONOGRAPHS ON FRAGRANCE RAW MATERIALS. CARVACROL; FOOD COSMET TOXICOL 17 (SUPPL) 743 (1979)

Carvacrol has known human metabolites that include (2-methyl-5-propan-2-ylphenyl) hydrogen sulfate and (2S,3S,4S,5R)-3,4,5-trihydroxy-6-(2-methyl-5-propan-2-ylphenoxy)oxane-2-carboxylic acid.
