ABSTRACT
The present study aimed at exploring the therapeutic potential of standard extract of Bombax ceiba L. leaves (BCE) in type 2 diabetic mellitus (T2DM). Oral administration of BCE at doses of 70, 140, and 280 mg·kg, to the normal rats and the high-fat-diet- and streptozotocin-induced T2DM rats were carried out. Effects of BCE on blood glucose, body weight, and a range of serum biochemical parameters were tested, and histopathological observation of pancreatic tissues was also performed. HPLC-ESI-Q/TOF-MS/MS analysis indicated that the chemical composition of BCE mainly contained mangiferin, isoorientin, vitexin, isomangiferin, isovitexin, quercetin hexoside, 2'-trans-O-cumaroyl mangiferin, and nigricanside. BCE caused a significant decrease in the concentrations of fasting blood glucose, glycosylated hemoglobin, total cholesterol, triglyceride, low density lipoprotein-cholesterol, serum insulin, and malondialdehyde, and increases in oral glucose tolerance, high density lipoprotein-cholesterol, and superoxide dismutase in the T2DM model rats. Moreover, considerable pancreatic β-cells protection effect and stimulation of insulin secretion from the remaining pancreatic β-cells could be observed after BCE treatment. The results indicated that BCE exhibited an excellent hypoglycemic activity, and alleviated dyslipidemia which is associated with T2DM. Antioxidant activity and protecting pancreatic β-cells are the possible mechanisms involved in anti-diabetic activity of BCE.

The present study was designed to explore the mechanism by which ethanol extract of Bombax ceiba leaves (BCE) and its main constituent mangiferin (MGF) affect diabetic nephropathy by combating oxidative stress. Oral administration of BCE and MGF to normal and streptozotocin (STZ)-induced diabetic mice were carried out. Fasting blood glucose, 24-h urinary albumin, serum creatinine, and blood urea nitrogen were tested, histopathology, and immunohistochemical analysis of kidney tissues were performed. Moreover, mesangial cells were treated with BCE and MGF for 48 h with or without 25 mmol·L of glucose. Immunofluorescence, Western blot and apoptosis analyses were used to investigate their regulation of oxidative stress and mitochondrial function. BCE and MGF ameliorated biochemical parameters and restored STZ-induced renal injury in the model mice. In vitro study showed that high glucose stimulation increased oxidative stress and cell apoptosis in mesangial cells. BCE and MGF limited mitochondrial membrane potential (Δψm) collapse by inhibiting Nox4, mitochondrially bound hexokinase II dissociation, and subsequent ROS production, which effectively reduced oxidative stress, cleaved caspase-3 expression and cell apoptosis. Our work indicated that BCE and MGF had protective effects on diabetic caused kidney injury and prevented oxidative stress in mesangial cells by regulation of hexokinase II binding and Nox4 oxidase signaling.

ABSTRACT
Aims: The present work was decided to evaluate the in-vitro anti-inflammatory activity of crude extracts of Bombax ceiba in order to characterize the role of this extract in affecting the inflammatory process. Study Design: Extraction of B. ceiba bark, phytochemical screening, and evaluation of invitro anti-inflammatory activity. Methodology: Petroleum ether, ethanol and aqueous extracts of B. ceiba barks were prepared by maceration technique and subjected to preliminary phytochemical tests. The in-vitro anti-inflammatory activity of all extracts (1000 mcg/ml) was assessed by HRBC membrane stabilization method. Results: Ethanol extract showed significant (p<0.001) response followed by aqueous extract (p<0.01) when compared with standard, diclofenac potassium (50 mcg/ml). Conclusion: The study suggests that the extracts possess enough potential to reduce inflammation by in-vitro and directs the importance of further research and development of novel anti-inflammatory agents.
ABSTRACT
The present study was designed to evaluate the cardioprotective potential of aqueous flower extract of Bombax ceiba L., Malvaceae (BC), on the basis of biochemical and histopathological parameters in Adriamycin (Adr) induced myocardial infarction in rats and to compare with vitamin E, a known cardioprotective antioxidant. Male Wister rats were used as in vivo model for the study. BC was administered orally to Wister rats at different doses (150 mg/kg, 300 mg/kg and 450 mg/kg, b.w.) for six days/week for four weeks. Thereafter, all the groups except saline were administered Adr (20 mg/kg, i.p.). There was a significant decrease in myocardial superoxide dismutase, catalase and reduced glutathione in animals treated with Adr. Concurrently marked increase in extent of lipid peroxidation was reported. Co-treatment of BC/vitamin E and Adr resulted in an increase in the cardiac antioxidant enzymes and reduction in lipid peroxidation as compared to Adr-treated animals. Adr showed significant decrease (p<0.001) in the level of cardiac marker enzymes [Lactate dehydrogenase (LDH) and Serum glutamic oxaloacetic transaminase (SGOT)] in heart homogenate with corresponding increase in their level in serum. In BC/vitamin E treated groups significant increase (p<0.001) of LDH in heart homogenate and decrease of SGOT and LDH in serum were observed. Microscopic studies in Adr-treated animals revealed mitochondrial swelling, leukocyte infiltration, lipid inclusions and myofibrillar loss whereas the pre-treatment with BC/vitamin E led to a lesser degree of Adr-induced histological alterations. These findings suggest that aqueous flower extract of BC has protective effect against Adr-induced cardiotoxicity and may have potential as a cardioprotective agent.
ABSTRACT
<p><b>OBJECTIVE</b>To examine the anti-bacterial activity of leaf extracts of Morus alba L. (Moraceae) and Piper betel L. (Piperaceae), and seed extracts of Bombax ceiba L. (Borabacaceae).</p><p><b>METHODS</b>We have partially purified plant extracts by solvent extraction method, and evaluated the effect of individual fractions on bacterial growth using Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus) bacterial strains.</p><p><b>RESULTS</b>Compared with Morus and Bombax fractions, Piper fractions showed significant growth inhibition on all the three types of bacteria studied. The EtOAc-hexane fractions of Piper leaves exhibited significant anti-bacterial activity with minimum inhibitory concentrations (MIC) of 50 µg/mL culture against both gram-positive and gram-negative bacteria. The EtOAc-fractions I, II, and IV inhibited bacterial colony formation on soft agar in addition to growth inhibition. A combination treatment of piper fractions with ampicillin resulted in significant growth inhibition in E. coli and P. aeruginosa, and combination with anticancer drug geldanamycin (2µg/mL) showed selective growth inhibition against P. aeruginosa and S. aureus. Three major compounds, i.e., eugenol, 3-hexene-ol and stigmasterol, were primarily identified from Piper betel leaf extractions. Among the individual compounds, eugenol treatment showed improved growth inhibition compared with stigmasterol and 3-hexene-ol.</p><p><b>CONCLUSIONS</b>We are reporting potential anti-bacterial compounds from Piper betel against both gram-positive and gram-negative bacteria either alone or in combination with drug treatment.</p>
