This study investigated the effects of four weeks of intake of a supplement containing dehydroepiandrosterone DHEA , androstenedione and herbal extracts on immune function in middle-aged men.
Subjects consumed either an oral placebo or an oral supplement for four weeks. The supplement contained a total daily dose of mg DHEA, mg androstenedione, mg Tribulus terrestris, mg chrysin, mg indolecarbinol and mg saw palmetto The preventive and therapeutic effects of saponin from Tribulus terrestris L. Study of antihypertensive mechanism of Tribulus terrestris in 2K1C hypertensive rats: Tribulus terrestris is a natural herb used for treating many diseases including hypertension.
According to previous reports, aqueous extract of tribulus fruits may have some antihypertensive effect with an unknown mechanism. The present study investigated the antihypertensive mechanism of tribulus in 2K1C hypertensive rats by measurement of circulatory and local ACE activity in aorta, heart, kidney and lung.
Four groups of rats were selected; control, sham, operated or hypertensive and tribulus treated hypertensive group Some aspects of chemical and pharmacological studies of Tribulus terrestris.
Furostanol saponins from Tribulus terrestris. Protodioscin, a new saponin 5,6-dihydroprotodioscin, neoprotodioscin and their respective sulfates were detected. A review of plant-derived and herbal approaches to the treatment of sexual dysfunctions.
Despite the increasing availability of effective conventional medical treatments, plant-derived and herbal remedies continue to provide a popular alternative for men and women seeking to improve their sex life.
Nevertheless, the efficacy of most herbal agents in treating sexual problems remains uncertain. Therapists and consumers alike would benefit from an increased understanding of commonly used herbal agents on the market, their purported or supported effects, and their potential side effects. To this end, we cataloged the major prosexual herbal agents currently sold in several representative health food stores Sexual effects of puncturevine Tribulus terrestris extract protodioscin: Apart from its claims for improvement of sexual functions in men, the puncturevine plant Tribulus terrestris: TT has long been considered as an energizer and vitalizer in the indigenous system of medicine.
Sexual behavior and intracavernous pressure ICP measurements were taken in rats to scientifically validate the claim of TT [containing protodioscin PTN ] as an aphrodisiac.
Forty sexually mature male Sprague-Dawley rats were randomly divided into four groups of 10 each Journal of Alternative and Complementary Medicine: Research on Paradigm, Practice, and Policy. The inhibitory effect of saponins from Tribulus terrestris STT on Bcap37 breast cancer cell line were determined by cell growth curve, MTT assay, protein content assay and morphological observation.
The results showed that STT had potent inhibitory effect on Bcap cell line in a concentration-dependent manner. Bcap cell exhibited morphological alteration, namely, cells got round and shrunk, nuclei contracted after treating with STT.
Zygophyllaceae which is called Al-Gutub in Iraqi dialect or Quti;ba in classical Arabic medicine , and Zea mays were both used alone or in combination by Iraqi herbalists to propel urinary stones. We studied the aqueous extract of the leaves and fruits of T. The aqueous extract was filtered and the solvent was evaporated to produce a dry crude extract Experimental Tribulus terrestris poisoning in sheep: Eleven native sheep, years old, of both sexes were randomly divided into two groups, 6 sheep being allocated to the experimental group and 5 serving as controls.
Clinical signs of hepatogenous photosensitivity were observed from day 11, including reddening and crust formation on the muzzle, nose, ears and eyelids, depression, weight loss, icterus, conjunctivitis, and yellow discoloration of the urine Tribulosin and beta-sitosterol-D-glucoside, the anthelmintic principles of Tribulus terrestris.
Both the compounds exhibited anthelmintic activity with ED50 of International Journal of Phytotherapy and Phytopharmacology. To study the hypoglycemic effect of saponin from Tribulus terrestris L. Alloxan was used to establish the diabetic model in mice. Phenformin Hydrochlride Tables was used as the positive control.
The level of glucose, triglyceride, cholesterol and SOD in serum were determined. The level of serum glucose could be significantly reduced by saponin from Tribulus terrestris, which was the rate of To investigate the chemical constituents of the fruit of Tribulus terrestris J..
Various chromatographic techniques were used to separate the chemical constituents. Two new compounds were isolated from the fruits of Tribulus terrestris J. It provided evidences for the identification of Tribulus terrestris L. To study the effects of the decoction of Tribulus terrestris L on tyrosinase activity and melanogenesis.
MTT was employed to study the proliferation of human melanocytes cultured in vitro, and tyrosinase activity was estimated by measuring the rate of oxidation of DL-dopa, after the cells were treated with different concentrations of decoction of Tribulus terrestris L. The treatment with the decoction increased the amount of melanin at higher concentrations but act to the reverse effect at lower concentrations, with the best concentrations for promoting and inhibiting the cell growth being Evaluation of natural products on inhibition of inducible cyclooxygenase COX-2 and nitric oxide synthase iNOS in cultured mouse macrophage cells.
The inhibitors of prostaglandin biosynthesis and nitric oxide production have been considered as potential anti-inflammatory and cancer chemopreventive agents.
In this study, we evaluated approximately methanol extracts of natural products including Korean herbal medicines for the inhibition of prostaglandin E 2 production for COX-2 inhibitors and nitric oxide formation for iNOS inhibitors in lipopolysaccharide LPS -induced mouse macrophages RAW To make clear the current situation of application of the Chinese medicinal herbs of Jili.
The medicinal resources and commodities of the berbs in some provinces and cities in China were investigated. The fruit of T. A new steroidal saponin from Tribulus terrestris Linn. Biologically active steroidal glycosides from Tribulus terrestris. The steroidal saponin constituents obtained from Tribulus terrestris were tested for their antimicrobial and cytotoxic effects.
The spirostanol-based steroidal saponins exhibited remarkable activity against fungal organisms Candida albicans and Cryptococcus neoformans and cancer cell lines [human malignant melanoma SK-MEL , human oral epidermoid carcinoma KB , human breast ductal carcinoma BT , and human ovary carcinoma SK-OV-3 ], while none of the compounds possessing the furostanol framework showed activity Sign in or create an account to discover new knowledge that matter to you.
