In the current study, five different plants, Syzygium Cumini, Fagonia cretica, Acacia modesta, Withania coagulans, and Olea europaea aqueous extracts were prepared and applied against the anticancer and antibacterial activities. It was observed that O. Europaea extract shows the highest anticancer activity with cell viability of 21.5%. All the five plants extract was also used against the inhibition of Bacillus subtilis where O. Europaea extract shows a promising inhibitory activity of 3.2 cm followed by W. coagulans. Furthermore, W. coagulans was subjected to the process of column chromatography as a result a withanolide was isolated. The fast atom bombardment mass spectrometry (FAB-MS) and high resolution fast atom bombardment (HRFAB-MS) [M + 1] indicated molecular weight at m/z 453 and molecular formula C28H37O5. The UV–Vis. spectrum shows absorbance at 210 nm suggesting the presence of conjugated system, and Fourier-transform infrared spectroscopy (FTIR) was recorded to explore the functional groups. Similarly, 1D and 2D NMR spectroscopy techniques such as 1H, 13C NMR, correlation spectroscopy (COSY-45°), heteronuclear single quantum correlation (HSQC), heteronuclear multiple bond correlation (HMBC) and Nuclear Overhauser effect Spectroscopy (NOESY) techniques was carried out to determine the unknown natural product. The collective data of all these techniques established the structure of the unknown compound and recognized as a withanolide.

This review provides critical insight regarding the phytochemistry, biological activities, and pharmacognostic properties of W. coagulans. It has been known to possess diuretic, anti-inflammatory, anti-bacterial, anti-fungal, cardio-protective, hepato-protective, hypoglycemic, anti-oxidative, and anti-mutagenic properties owing to the existence of withanolides, an active compound present in it. Apart from withanolides, W. coagulans also contains many phytochemicals such as flavonoids, tannins, and β-sterols. Several studies indicate that various parts of W. coagulans and their active constituents have numerous pharmacological and therapeutic properties and thus can be considered as a new drug therapy against multiple diseases.

An efficient protocol for in vitro regeneration from the nodal explants of Withania coagulans (Stocks) Dunal: a valuable medicinal herb

<p>In order to develop a protocol for the effective micropropagation of the important medicinal plant Withania coagulans (Stocks) Dunal, the effects of different concentrations and combinations of growth regulators on the nodal explants in two independent experiments were investigated. For shooting, a MS medium fortified with different concentrations and combinations of IBA (0.01, 0.1 and 0.5 mg l-1), BA (0.5, 1 and 2 mg l-1), Kin (0.5 and 1 mg l-1), PG (0.5 mg l-1) and GA (0.5 mg l-1) was used and the highest shooting response, shoot number and shoot length were obtained in the MS + IBA (0.01 mg l-1) + BA (0.5 mg l-1) + PG (0.5 mg l-1) + GA (0.5 mg l-1) treatment. In the second experiment, the effect of MS supplemented with different combinations and concentrations of IBA (0.1, 0.5, 1 and 2 mg l-1), NAA (0.1 and 1 mg l-1) and PG (1 mg l-1) on rooting of the nodal explants was investigated, which showed that the highest rooting response (%) was observed in the MS fortified with NAA (0.1 mg l-1), NAA (1 mg l-1), NAA (0.1 mg l-1) + PG (1 mg l-1), and NAA (1 mg l-1) + PG (1 mg l-1) treatments, as well as the highest number of roots at NAA (0.1 mg l-1) and the highest root length at IBA (1 mg l-1). Our findings highlight a complete micropropagation method for W. coagulans from the nodal explant that can make a significant contribution to the development of W. coagulans material for medical applications.</p>

Effect of Combined Extracts of Mummy, Withania Coagulans, and Turmeric on the Repair and Treatment of Bone Fractures in Rats

Background: Repair of broken bones due to physiological or pathological factors has always been important for researchers. In this regard, this study aimed to evaluate the effect of a combined extract on the osteogenic process in the experimental fracture created in the femoral of rats as laboratory models. Materials and Methods: This experimental study was performed on 21 rats. After induction of general anesthesia to each mouse, a 3-cm incision was made in the femoral bone and it was broken with a special hammer. After surgery, the control group did not receive any extract, while the three experimental groups received 200, 500, and 1000 mg/kg PO, respectively. In the next step, 21 days after surgery, euthanasia was performed and bone sections were prepared and stained in the fracture site. Next, histopathological and histomorphometric studies were carried out for the evaluation of bone healing in rats. The collected data were analyzed in SPSS software (version 21). Results: According to the pairwise comparison test, the mean difference of variables, namely bone marrow, woven bone, and lamellar bone of the third group of the test was significantly different from those of the other groups (P<0.05). This indicated that receiving the extract in the experimental groups with an increased dose led to a decrease in the mean bone marrow and woven bone which, in turn, increased the mean lamellar bone. Conclusion: The results showed that the combined extracts of mummy, Withania coagulans, and turmeric can stimulate osteogenesis in rats and be considered as a candidate for fracture treatment.

The effects of camel chymosin and Withania coagulans extract on camel and bovine milk cheeses

Withania coagulans (W. coagulans) extract and camel chymosin have aspartic protease capable of coagulating milk for cheese production. This study investigated the quality of camel and bovine milk cheeses coagulated using Withania extracts, came chymosin, and their mixture in two experiments. In Experiment (1), a factorial design with four factors (W. coagulans, camel chymosin, incubation time, and incubation temperature) was performed. The effect of these factors on cheese’s yield and hardness were assessed. An enzyme concentration corresponding to a 36 µg/L of milk of W. coagulans, 50 IMCU/L of camel chymosin, holding time of 4 h, and incubation temperature of 60 °C provided the optimal textural hardness for both camel and bovine milk cheeses. Seven treatments were analyzed in experiment (2) were analyzed for physicochemical properties, yield, and sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGEitation). The results showed that pure Withania extract exhibited the lower coagulating effect resulting in cheeses with low yield, hardness, fat, protein, and total solids. The SDS-PAGE electropherograms of camel cheese showed several low molecular weight bands as compared to bovine cheese. This phenomenon is due to excessive proteolysis in camel cheese, which we believed is caused by the presence of endogenous enzymes.
