Albino male wistar rats (120–150 g) were split into various groups, each of which had six individuals. Normal rats (group I) were received 0.3% carboxy methyl cellulose (CMC) with a standard laboratory diet, while hyperlipidemic rats (group II, III, IV, V, VI and VII) were fed high-fat diet for induction of hyperlipidemia. Hyperlipidaemic control group (group II) received 0.3% CMC (10 mL/kg/day), standard group (group III) received gemfibrozil (50 mg/kg/day, p.o.), HBAE groups (group IV and V) received aqueous extract of H. benghalensis (100 and 200 mg/kg/day, p.o.), and HBEE groups (group VI and VII) received an ethanolic extract of H. benghalensis (100 and 200 mg/kg/day, p.o.), concurrent with high fat diet for consecutive four weeks. The HBAE and HBEE treatments led to a significant (p < 0.05) reduction in serum lipids (TC, TG, LDL and VLDL) and elevation in cardioprotective HDL, when compared to hyperlipidaemic rats (group II). Phytochemical screening revealed the presence of phytoconstituents such as alkaloids, flavonoids, saponins, tannins, phenolic compounds and steroids, which may be attributed to observed hypolipidemic effects.

The evolution of multi-drug resistant bacteria shifted the focus of researchers towards traditional medicine involving bioactive compounds. Plants with bioactive compounds play a pivotal role in treating human diseases. Many of the plant-based bioactive compounds were proven to have the ability to inhibit bacterial growth through different modes of action. Thus, plant-based compounds have been focused on finding potential molecules with antibacterial efficiency to overcome bacterial infection problems. So, in the present study, phytocompounds of Sida acuta Burm F. leaf extract were identified using GC-MS technique and phytocompounds with antibacterial potential were identified through a molecular docking study. The qualitative test carried out indicated the presence of carbohydrates, alkaloids, phenols, terpenoids, flavonoids, amino acids, steroids, glycosides, saponins, quinones and coumarins in the extract. The GC-MS analysis showed the presence of 30 phytocompounds and molecular docking studies revealed the best binding affinity of the phytocompounds Pyrido[1,2-a]pyrimidine, Acetonitrile,2-(6-phenantridinyl), 5H-Imidazo(2,1-a)isoindole,2-phenyl and Pyrido[1,2-a]pyrimidine towards E. coli biomolecules- 1PHO, 5I5H, 5UW2 and 6NTW respectively.

In Ayurveda, these herbs have been known to be conducive to heart. The present study was designed to evaluate the cardioprotective action of two herbs of Hridya dashemani fruits of Karamarda (Carissa carandas L.) and fruits of Badara (Ziziphus jujuba Lam.)] on the basis of biochemical&histopathological parameters in isoprenaline (ISO) induced myocardial infarction (MI) in experimental rats and to compare with stem bark of Arjuna (Terminalia arjuna (Roxb.ex.DC.) Wight&Arn.), a well-known cardioprotective herb. Total 36 male wistar albino rats were randomly divided into six groups. Group I- normal control (NC), group II- ISO induced MI, group IIIpositive control with hesperidin (100 mg/kg b.w), group IV- Badara (Z. jujuba – 450 mg/kg b.w), group V- Karamarda (C. carandus – 450 mg/kg b.w), group VI- Arjuna (T. arjuna – 450 mg/kg b.w). After 21 days of pre-treatment, experimental MI was induced in all groups except NC by injecting ISO subcutaneously (85 mg/kg) on 19th&20th day at an interval of 24 hours. Serum biochemical parameters, including cardiac biomarkers and histopathological examination of heart tissues were evaluated. ISO treated rats had a significant (p < 0.05) elevation in serum levels of diagnostic marker enzymes (AST, ALT, CK-MB, LDH, ALP) when compared to NC. All the pre-treated groups had significantly (p < 0.05) reduced marker enzyme serum levels compared to the ISO treated control. The protective role of these herbs was further confirmed by histopathological examination. The comparison revealed that Karamarda (C. carandus) pre-treated had similar protective effect as Arjuna (T. arjuna) in various biochemical parameters (AST, ALT, ALP, LDH, CK-MB, HDL, cholesterol, creatinine). It may be concluded from the present study that 450 mg/kg b.w of water extract of the above herbs have cardioprotective action against isoprenaline induced MI, with Karamarda (C. carandus), Arjuna (T. arjuna) having almost similar effects.

It is also approved in many countries for multiple uses in solid tumors. The current marketed formulation lacks the tumortargeting ability, and its uneven distribution in the body causes toxicity to normal tissues. Further, it is a surfactant (polysorbate 80) based micellar formulation composed of ethanol as a co-solvent to improve the solubility of CTX, which causes severe and life-threatening side effects. Hence, to avoid the problem\u0000associated with this conventional CTX formulation, the nanoparticulate drug delivery system of CTX was\u0000developed by employing the Quality by Design (QbD) approach. The CTX nanoparticulate system was\u0000developed by employing a bottom-up followed by a top-down approach. The size reduction was obtained\u0000by High-Pressure Homogenizer (HPH). The formulation optimization was done using QbD approach. Design\u0000of experiments (DoE) was used to understand the effect of various formulation and process variables on\u0000a dependent variable like particle size distribution.\u0000The stabilizer concentration, concentration of solubilizer, HPH pressure, and passes were selected as\u0000independent factors while particle size distribution was selected as a dependent factor for evaluation.\u0000The nanoparticulate system was developed using PEG-400 as solubilizing agents, while Soya\u0000Phosphatidylcholine (SPC) was used as a surface stabilizer. Response surface plots revealed a decrease in\u0000particle size with increasing concentration of SPC and PEG 400. Similarly, a decrease in particle size with increased HPH passes and pressure was found. The optimum concentrations of SPC and PEG 400 were\u0000found to be 20% and 2.5%, respectively. 20 KPSI pressure and 5 HPH passes were derived as optimized\u0000processing parameters from DoE. The optimized formulation had a size of 43.5 nm, with PDI is less than 0.4. Due to its narrow particle size distribution, the formulation did not show any increase in particle size or aggregation up to 24 hours. The present research confirms the feasibility of developing the nanoparticulate system of CTX using the bottom-up followed by the top-down technique.

Total 12 marketed formulations were selected and analyzed in NABL (National Accreditation Board for Testing and Calibration Laboratories) accredited laboratory using High-performance liquid chromatography (HPLC) and inductively coupled plasma-mass-spectrometry (ICP-MS). The quantified values were compared with label-stated values and recommended values as per FSSAI. The quantified values in two lycopene samples varied significantly (-16 and +16%) from the label stated content and were found non-compliant with the regulatory recommendations. The measured intake values of calcium and vitamin D varied from 24 to 204% from the recommended daily allowances established by FSSAI. The quantified daily intake values varied from 4.2 to 58 mg and from 4 to 21.5 mg for lycopene and lutein, respectively. Heavy metal content determination resulted in two samples deviating from the tolerance limits of heavy metals for lead and arsenic. The mean values for lead and arsenic were found to be 2.482 ± 6.921 and 0.311 ± 0.655 ppm, respectively.
