Phytochemical analysis and thrombolytic profiling of Costus afer stem fractions

Background The most commonly occurring mechanism driving ischemic heart disease, ischemic stroke, and myocardial infarction is thrombosis. It is normally characterized by platelet activation and aggregation. Thrombolytics have been used in the treatment of several forms of thrombosis, but their adverse effects have limited their usefulness. Thus, there is a need to develop alternatives from medicinal plants known to possess antithrombotic activity such as Costus afer. Results The phytochemical evaluations indicated the presence of flavonoids, alkaloids, cardiac glycosides, tannins, terpenoids, and saponins. The antithrombotic profiling showed that streptokinase had the highest percentage clot lysis, followed by ethylacetate fraction of the extract, which was higher than aspirin and other fractions of the extract. Conclusion The present findings show that C. afer stem extract and various fractions possess antithrombotic activities. However, further studies are needed to characterize the antithrombotic bioactive compounds present in the different fractions that are responsible for the activities.

Standardization of zygotic embryo culture from Nerium oleander L. and comparative analysis of biosynthesized cardiac glycosides within in vitro and acclimatized plants

The primary result of our experiment revealed that the germination percentage of N. oleander mature seeds is only 30%. From this observation, the concept of protocol standardization for zygotic embryo culture of this plant was originated. Zygotic embryo culture was proved an efficient in vitro multiplication system of N. oleander. The maximum germination percentage (96%) of zygotic embryos was observed on ¼ MS medium with 15 gm/L sucrose, whereas the best growth medium was optimized as ½ B5 with same sucrose concentration. The second part of this study was aimed to find out the cardiac glycoside accumulation pattern in both in vitro and acclimatized plants. For this purpose, one-month-old in vitro plantlets and acclimatized plants were subjected to LC-MS analysis and 09 cardiac glycosides were detected and quantified in both the systems. Most of the cardiac glycosides including odoroside A (32.71 mg/gm DW), odoroside H (4.69 mg/gm DW) and oleandrin (0.52 mg/gm DW) were found to be accumulated at maximum level within in vitro plantlets. CG 840b (1.89 mg/gm DW) is the only cardiac glycoside, which was maximally accumulated in acclimatized plants. From this study, it can be concluded that, zygotic embryo culture is a better choice for in vitro multiplication of N. oleander when compared to matured seeds and in vitro grown plantlets of this species favor cardiac glycosides biosynthesis in comparison to acclimatized plants. Therefore, all future research on the enrichment of cardiac glycosides from this plant may be conducted on zygotic embryos derived in vitro grown plantlets or cultures.

Cardiac Glycosides – The Review of Remedies in congestive heart Failure

Congestive heart failure, occurs when our heart muscle doesn't pump blood as well as it must. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently. Herbal drugs like digitalis, squill, and stropanthus commonly find the treatment of heart diseases. Caridio active glycosides like having the purpurea glycosides A and B present in the herb of digitalis, glucoscillaren A and scillarenase having the squill and strophanthus having strophanthoside.

Efficacy of Herbal Medicine Administration using Neem (Azadirchta indica L) Leaves as Case Study

Plants used for treatment of diverse ailments primitively are concocted and used indiscriminately. The efficacy of "Herbal medicine" which is an ancient tradition, used in some parts of Nigeria was investigated to establish herbal applications of Neem (Azadirachta indica) leaves. Neem leaves (Azadirachta indica) was popularly recognised for the treatment of malaria fever. The leaves were plucked at appropriate peak period of the day when oil and moisture contents were recorded maximum. The peak period of contents was found to occurred between 8am-10am on a very sunny days, 10am to 12 on cool days, and 3:00pm to 5:00pm on cloudy days. Aqueous extract from macerated Neem leaves was subjected to qualitative and quantitative analysis. Available phytochemicals evaluated include; saponin (34.89mg/g), tannin (31.715mg/g), flavonoid (31.835mg/g), phenol (43.59mg/g), terpernoid (14.585mg/g), cardiac glycosides (39.335mg/g), steroid (16.185mg/g) and alkaloid (28.76mg/g). These values differ significantly to recommended oral dosage formulation for human consumption: Saponin (1.433ml), Tannin (1.418ml), Flavonoid (13.91ml), Phenol (2.29ml), Terpernoid (8.23ml), Cardiac Glycosides (0.003177ml), Steroid (0.62mg/g). Consequently, local consumption of herbal resources should be regulated to avoid abuse and long or short-term effects of drug contents as proven in the neem leaves as local herbs.

A Review on Cardioprotective Mechanism of Chemical Constituents of Medicinal Plants

Plants are the major source of human living. Since the beginning of the era, plants have been used for medicinal purposes. There is dire to explore the mechanism of chemical constituents in plants and particularly saponins, cardiac glycosides, and flavonoids due to their mechanism to save damaged cells in cardiac muscle. Databases like Google Scholar, Medline, PubMed, and the Directory of Open Access Journals were searched to find the articles describing the cardioprotective mechanism of medicinal plants. Saponin, flavonoids, glycoside, steroid, alkaloids, tannin, phenol, phlorotannin, terpenoids, and anthraquinone are chemical constituents in plants that enhance cardioprotection activity and decreases cardiac abnormalities. The current review article provides data on the use of medicinal plants, specifically against cardiac diseases, as well as an investigation of molecules/phytoconstituents as plant secondary metabolites for their cardioprotective potential.

Monovalent Ions and Stress-Induced Senescence in Human Mesenchymal Endometrial Stem Cells

Monovalent ions are involved in growth, proliferation, differentiation of cells as well as in their death. This work concerns the ion homeostasis during senescence induction in human mesenchymal endometrium stem cells (hMESC): hMESCs subjected to oxidative stress (pulse H2O2 treatment) enter the premature senescence accompanied by persistent DNA damage, irreversible cell cycle arrest, cell hypertrophy, lipofuscin accumulation, enhanced β-galactosidase activity. Using flame photometry to estimate K+, Na+ content and Rb+ (K+) fluxes we found that during the senescence development in stress-induced hMESCs, Na+/K+pump-mediated K+ fluxes are enhanced due to the increased Na+ content in senescent cells, while ouabain-resistant K+ fluxes remain unchanged. Senescence progression is accompanied by a peculiar decrease in the K+ content in cells from 800-900 µmol/g to 500-600 µmol/g. Since cardiac glycosides are offered as selective agents for eliminating senescent cells, we investigated the effect of ouabain on ion homeostasis and viability of hMESCs and found that in both proliferating and senescent hMESCs, ouabain (1 nM-1 µM, 24-48 h) inhibited pump-mediated K+ transport (ID50 5x10-8 M), decreased cell K+/Na+ ratio to 0,1-0,2, however did not induce apoptosis. Comparison of the effect of ouabain on hMESCs with the literature data on the selective cytotoxic effect of cardiac glycosides on senescent or cancer cells suggests the ion pump blockade and intracellular K+ depletion should be synergized with target apoptotic signal to induce the cell death.
