Constituents of Aristolochia indica
The plant contain aromatic oil (0.5%), coloring material, and an alkaloid (aristolochine 0.05-0.07%).
- Aristolochic acid (0.06-0.07%), glycosides, and steroids are present in rhizome.
- Aristolochic acids
- Aristolochic acids are a family of carcinogenic, mutagenic, and nephrotoxic compounds commonly found in the birthwort family of the plants. It functions as a phospholipase A2 inhibitor, antiseptic, anti-inflammatory, and bactericidal agent. Aristolochic acid is composed of a 1:1 mixture of two forms, Aristolochic acid I, and Aristolochic acid II.
Aristolochic acid I
- IUPAC Systematic Name: 8-Methoxy-6-nitronaphtho[2,1-g][1,3]benzodioxole-5-carboxylic acid
- Chemical formula: C17H11NO7
- Relative molecular mass: 341.27
Aristolochic acid II
- IUPAC Systematic Name: 6-Nitronaphtho[2,1-g][1,3]benzodioxole-5-carboxylic acid
- Chemical formula: C16H9NO6
- Relative molecular mass: 311.25
Aristolochic acid, tested for carcinogenicity in several studies. A study done in mice, and another in rabbits, showed internal administration of this compound induced tumors at multiple sites in the body of animals.
The oral administration of aristolochic acid to rats caused a dose-, and time-dependent tumor response. Exposure to 50 mg/kg body weight aristolochic acid I for 3 days resulted in neoplastic lesions of the kidney after 6 months.
Rats administered with lower doses over a longer period (1-10 mg/kg body weight for 3–6 months or 0.1 mg/kg body weight for 12 months) developed a variety of benign or malignant tumors, including those of the forestomach, kidney, renal pelvis, urinary bladder, ear duct, thymus, small intestine, and pancreas. Single cases of haematopoietic system, lung, mammary gland, and peritoneal tumors were also reported.
Injecting, 10 mg/kg bodyweight aristolochic acid into rats for 35 daysinduced a low incidence of urothelial carcinomas, and fibrohistiocytic sarcomas at the injection site.
Rabbits given intraperitoneal injections of aristolochic acid at 0.1 mg/kg body weight for 17-21 months developed tumors of the kidney, ureter, and of the peritoneal cavity.
Food, and Drug Administration (FDA) warns against use of herbs containing Aristolochic acid due to their ill-effects on kidneys. It has been associated with permanent kidney damage, and kidney failure. Few people have developed certain types of cancers, most often occurring in the urinary tract.
In May 2000, FDA alerted health care professionals, and the dietary supplement industry of two patients in the United Kingdom who had experienced serious, permanent kidney damage following the use of botanical products containing aristolochic acid. These cases, along with the ones previously reported from Belgium, and France, resulted in FDA imposing an import alert to detain botanical ingredients that are either labeled as “Aristolochia” or, for other reasons, are suspected to contain aristolochic acid.
FDA has advised consumers to stop using any products that may likely contain aristolochic acid.
