Effects on rats of Commiphora myrrha extract given by different routes of administration.

The effect of an ethanol extract of Commiphora myrrha oleo-gum resin on hematological and pathophysiological parameters of male Wistar rats was examined. The extract was given daily for 2 w at 1000 mg/kg bw per os, 500 mg/kg bw i.m. or 250 mg/kg bw i.p. Depression, huddling together, soft feces, jaundice, ruffled hair, hepatonephropathy, hemorrhagic myositis and patchy peritonitis (at the injection site) and death were accompanied by increases in serum ALP and ALT activities, bilirubin, cholesterol and creatinine concentrations, and decreases in total protein and albumin levels, and macrocytic anemia and leucopenia. When administered at 500 mg extract/kg bw/d per os or 250 mg extract/kg bw/d i.m. for 2 w it was not lethal, and when given daily for 1 w the effect was less marked.

Toxicity of Commiphora myrrha to goats.

An investigation was made of Commiphora myrrha used in traditional medicine for the treatment of various ailments. Twelve 6-mo-old male Nubian goat kids were assigned to 4 groups: undosed controls, C myrrha-dosed at 0.25 g plant resin/kg/d, C myrrha-dosed at 1 g resin/kg/d and C myrrha dosed at 5 g plant resin/kg/d. Results of hepatorenal function tests were correlated with clinical and pathological changes. The use of 1 or 5 g plant resin/kg/d caused grinding of teeth, salivation, soft feces, inappetence, jaundice, dyspnea, ataxia and recumbency. Death occurred between 5 and 16 d. Enterohepatonephrotoxicity was accompanied by anemia, leucopenia, increases in serum ALP activity and concentrations of bilirubin, cholesterol, triglycerides and creatinine, and decreases in total protein and albumin. The oral dose of 0.25 g plant resin/kg/d was not toxic.

Larvicidal activity of Commiphora molmol against Culex pipiens and Aedes caspius larvae.

Myrrh (oleo-gum-resin) obtained from the stem of Commiphora molmol proved to have insecticidal activity against mosquito larvae. The oil extract of Myrrh possesses median lethal activity against 2nd, 3rd and 4th instar larvae of Culex pipiens at 0.016 x 10(2), 0.17 x 10(2) & 1.6 x 10(2) g/l respectively. While LC50 against 3rd instar larvae of Aedes caspius was 0.2 x 10(2) g/l. The oleo-resin extract showed toxicity against 2nd, 3rd, 4th instar larvae of C. pipiens recording the LC50 values of 0.06 x 10(2), 0.09 x 10(2) & 0.5 x 10(2) g/l respectively. While LC50 against 3rd instar larvae of A. caspius was 0.08 x 10(2) g/l. This plant extract has no marked toxic effect against the water bug Sphaerodema urinator (Dufor) and the water beetle Hydaticus leander (Rossi). Histological examinations of Myrrh treated mosquito larvae showed great pathological effect on their fat, muscles, gut and nervous tissues.

Simultaneous determination of E- and Z-guggulsterones in dietary supplements containing Commiphora mukul extract (guggulipid) by liquid chromatography.

Guggulipid, the standardized product from the extraction of the ole-gum-resin from the Commiphora mukul plant, has been marketed as a hypolipidemic agent. The ketosteroids, cis- and trans-4,17(20)-pregnadiene-3,16-dione, known as E- and Z-guggulsterones, respectively, are the main ingredients in guggulipid. A liquid chromatographic method was developed for simultaneous determination of E- and Z-guggulsterones in guggulipid preparations using synthetic E- and Z-guggulsterone standards. Realtively low amounts of guggulsterones (E and Z) were found in commercial guggulipid preparations in comparison with the manufacturer's claim of 2.5%. The mixture of E- and Z-guggulsterones was extracted and separated on a Symmetry C18 reversed-phase column, with a mobile phase of acetonitrile--water (46 + 54, v/v) and detected at 242 nm. The retention times of E- and Z-guggulsterones are approximately 8 and 11 min, respectively. Assay quantitation was based on the calibration curve obtained from a mixture of synthetic standard E- and Z-guggulsterones. Experimental data on selectivity, linearity, accuracy, and recoveries are presented.

Biochemical changes of Culex pipiens larvae treated with oil and oleo-resin extracts of Myrrh Commiphora molmol.

The mosquitocidal plant extracts of the Myrrh, Commiphora molmol namely; oil and oleo-resin, were proved to demonstrate larvicidal activity against Culex pipiens larvae. Oleo-resin was found to induce significant higher toxic action than oil. Solvent (cremophore EL) did not perform any toxic activity. The Impact of both oleo-resin and oil extracts on the protein profile of the treated larvae was evaluated in order to explain their mode of action. Electrophoretic analysis of total proteins, lipoproteins and glycoproteins revealed inhibitory action of the used plant extracts on the protein contents. Larvicidal activity of the oleo-resin and oil was explained as to be related to the loss of certain enzymes inhibited by these extracts which affect the metabolic processes.

Beneficial effects of Allium sativum, Allium cepa and Commiphora mukul on experimental hyperlipidemia and atherosclerosis--a comparative evaluation.

Oral administration of petroleum ether extract of Allium sativum, Allium cepa and ethylacetate extract of Commiphora mukul in albino rats significantly prevented rise in serum cholesterol and serum triglyceride level, caused by atherogenic diet. All the three agents were also found to confer significant protection against atherogenic diet induced atherosclerosis.

Comparison of the anti-inflammatory activity of Commiphora mukul (an indigenous drug) with those of phenylbutazone and ibuprofen in experimental arthritis induced by mycobacterial adjuvant.

In the present investigation a method of induction of experimental arthritis in animals was modified to provide a better model replica of human arthritis. Inflammatory syndrome, resembling rheumatoid arthritis in man, was induced in the right hock joint of albino rabbits by intra-articular injection of the killed mycobacterial adjuvant in liquid paraffin. Development of this arthritic syndrome was studied from a period of five months with and without drugs. Anti-inflammatory agents such as phenylbutazone, ibuprofen and fraction "A" of gum-guggual from Commiphora mukkul were administered orally at a daily dose of 100, 100 and 500 mg/kg, respectively, for a period of five months. All three drugs decreased the thickness of the joint swelling during the course of drug treatment. These results indicate the beneficial role of phenylbutazone, ibuprofen and fraction "A" of gum-guggul in experimental arthritis.

Hypolipidemic activity of guggal resin (Commiphora mukul) and garlic (Alium sativum linn.) in dogs (Canis familiaris) and monkeys (Presbytis entellus entellus Dufresne).

1. The identification of cholesterol as a constituent in the genesis of coronary artery disease in man and experimental animals are well documented. 2. The hypolipidemic effects of Commiphora mukul (guggulu) and Alium sativum (Garlic powder) were screened in dog and Presbytis monkeys. 3. Progressive decrease in the mean values of cholesterol, triglycerides and phospholipids were conspicuous for forty eight hours following the administration of guggulu/garlic powder. 4. 25 mg/kg body weight garlic powder was more effective in lowering the serum cholesterol and triglycerides as compared with that of guggulu. 5. A comparative hypolipidemic action of the two compounds is discussed.

Hypolipidemic and antioxidant effects of Commiphora mukul as an adjunct to dietary therapy in patients with hypercholesterolemia.

The effects of the administration of 50 mg of guggulipid or placebo capsules twice daily for 24 weeks were compared as adjuncts to a fruit- and vegetable-enriched prudent diet in the management of 61 patients with hypercholesterolemia (31 in the guggulipid group and 30 in the placebo group) in a randomized, double-blind fashion. Guggulipid decreased the total cholesterol level by 11.7%, the low density lipoprotein cholesterol (LDL) by 12.5%, triglycerides by 12.0%, and the total cholesterol/high density lipoprotein (HDL) cholesterol ratio by 11.1% from the postdiet levels, whereas the levels were unchanged in the placebo group. The HDL cholesterol level showed no changes in the two groups. The lipid peroxides, indicating oxidative stress, declined 33.3% in the guggulipid group without any decrease in the placebo group. The compliance of patients was greater than 96%. The combined effect of diet and guggulipid at 36 weeks was as great as the reported lipid-lowering effect of modern drugs. After a washout period of another 12 weeks, changes in blood lipoproteins were reversed in the guggulipid group without such changes in the placebo group. Side effects of guggulipid were headache, mild nausea, eructation, and hiccup in a few patients.

Minor components with smooth muscle relaxing properties from scented myrrh (Commiphora guidotti).

All sesquiterpenes present in a sample of scented myrrh were isolated and characterised. Seven compounds, with cadinane, guaiane, oplopane, and eudesmane skeletons, were obtained, of which two are new and two are reported from a natural source for the first time. The major component, T-cadinol, has previously been shown to possess smooth muscle-relaxing properties, and the major purpose of the investigation was to compare the effects of the minor and more polar sesquiterpenes with that of T-cadinol in the rat aorta. Like T-cadinol, the minor sesquiterpenes are more efficient in reducing K(+)-induced contractions than those induced by the alpha-adrenoceptor agonist phenylephrine, however, they were all less potent than T-cadinol.
