Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Clerodendrum infortunatum L. is commonly distributed in tropical and subtropical countries and is widely used in the indigenous systems of medicine including Ayurveda, Unani, and Homeopathy. The plant has important uses in the treatment of various inflammatory disorders which includes asthma, cough, chest complaints, pain, rheumatism, osteoarthritis, gastric ulcer, cancer, diabetes, skin diseases etc. AIM OF THE STUDY: Regarding the extensive healing properties of C. infortunatum in folk medicine, we aimed to explore the anti-inflammatory activity of the plant and analyze its bioactive components. MATERIALS AND METHODS Sequential extracts were prepared from C. infortunatum leaves using n-hexane, dichloromethane, ethyl acetate, methanol, ethanol and water. In vitro anti-inflammatory activity of these extracts were evaluated using membrane stabilization and protein anti-denaturation assays. Toxicity of the extracts was tested using brine shrimp lethality assay. GC-MS analysis has been carried out to analyze and characterize various bioactive constituents present in the plant. RESULTS Each of the tested extracts showed significant (p < 0.05) in vitro anti-inflammatory activity. Sequential ethyl acetate extract demonstrated the strongest membrane stabilization and protein anti-denaturation activities with IC50 values of 331.3, 308.3 and 279.2 μg/mL for heat and hypotonicity induced membrane stabilization and protein anti-denaturation assays, respectively. Sequential methanol extract also exhibited strong activity in heat and hypotonicity induced membrane stabilization and protein anti-denaturation assays with IC50 values of 371.5, 331.6 and 284.6 μg/mL, respectively. The extracts demonstrated a range of toxicity in the brine shrimp lethality assay with LC50 values of 51.4, 59.7, 47.3, 37.1, 68.1 and 77.3 μg/mL for n-hexane, dichloromethane, ethyl acetate, methanol, ethanol and water extracts respectively. The GC-MS analysis of direct n-hexane, ethyl acetate and methanol extracts detected 32 different compounds. The major compounds (> 5%) were phenol, 3,5-bis(1,1-dimethylethyl)-, hexadecanoic acid methyl ester, estragole, methyl stearate, lanosterol, 9-methoxybicyclo[6.1.0]nona-2,4,6-triene, benzenepropanoic acid, 3,5-bis(1,1-dimethylethyl) 4 hydroxy methyl ester, 22,23-dibromostigmasterol acetate, 3-methyl-4-(phenylthio)-2-prop-2-enyl-2,5-dihydrothiophene 1,1-dioxide, benzenemethanol, α-methyl-α-propyl- and 9-octadecenoic acid (Z)- methyl ester. CONCLUSIONS The findings of our study revealed that C. infortunatum is rich with diverse bioactive phytoconstituents and the scientific evidences support the anti-inflammatory potential of the plant.

Abstract
The raising concern of drug resistance, having substantial impacts on public health, has instigated the search of new natural compounds with substantial medicinal activity. In order to find out a natural solution, the current study has utilized prodigiosin, a linear tripyrrole red pigment, as an active ingredient to control bacterial proliferation and prevent cellular oxidation caused by ROS (Reactive Oxygen Species). A prodigiosin-producing bacterium BRL41 was isolated from the ancient Barhind soil of BCSIR Rajshahi Laboratories, Bangladesh, and its morphological and biochemical characteristics were investigated. Whole genome sequencing data of the isolate revealed its identity as Serratia sp. and conferred the presence of prodigiosin gene cluster in the bacterial genome. "Prodigiosin NRPS", among the 10 analyzed gene clusters, showed 100% similarity with query sequences where pigC, pigH, pigI, and pigJ were identified as fundamental genes for prodigiosin biosynthesis. Some other prominent clusters for synthesis of ririwpeptides, yersinopine, trichrysobactin were also found in the chromosome of BRL41, whilst the rest displayed less similarity with query sequences. Except some first-generation beta-lactam resistance genes, no virulence and resistance genes were found in the genome of BRL41. Structural illumination of the extracted red pigment by spectrophotometric scanning, Thin-Layer Chromatography (TLC), Fourier Transform Infrared Spectroscopy (FTIR), and change of color at different pH solutions verified the identity of the isolated compound as prodigiosin. Serratia sp. BRL41 attained its maximum productivity 564.74 units/cell at temperature 30˚C and pH 7.5 in two-fold diluted nutrient broth medium. The compound exhibited promising antibacterial activity against Gram-positive and Gram-negative bacteria with MIC (Minimum Inhibitory Concentration) and MBC (Minimum Bactericidal Concentration) values ranged from 3.9 to15.62 μg/mL and 7.81 to 31.25 μg/mL respectively. At concentration 500 μg/mL, except in Salmonella enterica ATCC-10708, prodigiosin significantly diminished biofilm formed by Listeria monocytogens ATCC-3193, Pseudomonas aeruginosa ATCC-9027, Escherichia coli (environmental isolate), Staphylococcus aureus (environmental isolate). Cellular glutathione level (GSH) was elevated upon application of 250 and 500 μg/mL pigment where 125 μg/mL failed to show any free radical scavenging activity. Additionally, release of cellular components in growth media of both Gram-positive and Gram-negative bacteria were facilitated by the extract that might be associated with cell membrane destabilization. Therefore, the overall findings of antimicrobial, antibiofilm and antioxidant activities suggest that in time to come prodigiosin might be a potential natural source to treat various diseases and infections.

Abstract
Curcuma longa L. (turmeric), Beta vulgaris L. (beetroot), and Daucus carota L. (carrot) grown in Bangladesh were analyzed for nutritional and phytochemical contents to reveal their comparative nutritional compositions and antiradical properties. Ash, protein, and carbohydrate content were significantly preeminent in beetroot as compared to others. Whereas fat content was found to be high in turmeric, carrots contained a great percentage of crude fiber. Beetroot was shown to have much greater potassium, calcium, and iron levels than others. Regarding amino acids, glutamic acid was found to be greater in beetroot and carrot whereas turmeric had significantly high aspartic acid content. Leucine had the highest concentration among essential amino acids in these three samples. Total antioxidant activity, total flavonoids, and phenolic contents in the methanolic extract of turmeric were found to be substantially higher than in beetroot and carrot. Furthermore, the extract of turmeric (IC50 value: 13.46 μg/mL) scavenged 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) free radicals considerably to a greater extent than beetroot (IC50 value: 380.61 μg/mL) and carrot (IC50 value: 1252.85 μg/mL). A positive correlation was found between the phytochemical contents and antiradical activity. The information from this study will help to find the potential ingredients from these plants for functional food.

Abstract
Pumpkin (Cucurbita maxima) is a widely grown vegetable in Bangladesh and is known as the sole supplier of various nutrients. Many studies evidence the nutritional value of flesh and seed while peel, flower, and leaves were reported scarcely with limited information. Therefore, the study aimed to investigate the nutritional composition and antioxidant properties of flesh, peel, seed, leaves, and flowers of Cucurbita maxima. The seed had a remarkable composition of nutrients and amino acids. Flowers and leaves possessed higher content of minerals, phenols, flavonoids, carotenes, and total antioxidant activity. The order of IC50 value (peel > seed > leaves > flesh > flower) indicates higher DPPH radicals scavenging activity of the flower. Moreover, a significant positive relationship was observed among these phytochemical constituents (TPC, TFC, TCC, TAA) and DPPH radicals scavenging activity. It could be concluded that these five parts of the pumpkin plant have an intense potency to be an exigent component of functional food or medicinal herbs.
