Plumeria alba Linn. belonging to the family Apocynaceae (Dogbane family) is the flowering plant. P. alba is used as a purgative, rubefacient in rheumatism, asthma, piles, gonorrhea, blood disorders and tumors, mentioned in the traditional system of medicine. The present study was carried out to establish the pharmacognostic studies, physicochemical parameters along with a preliminary phytochemical screening of various extracts of P. alba leaves. The methanolic extract of the leaves of the plant was screened for anti-diarrheal potentiality. The macroscopical and microscopical characteristics of powdered drug were studied. The transverse section of leaf indicated the arrangement of various cells in epidermal, lamina, and midrib regions. The preliminary phytochemical screening of various extracts revealed the presence of phytoconstituents, including alkaloid, glycosides, phenolic and tannins, flavonoids, and sterols. The physicochemical parameters such as total ash and acid insoluble ash (9.5 and 7.3% w/w respectively), loss on drying (0.5% w/w), and extractive values water-soluble and alcohol-soluble (10.0 and 4.2% respectively) of powder drug were studied. These studies will be helpful to establish...

Bastar is endowed with a unique blend of traditional knowledge and rich floral diversity. The region is known as the island of Shorea robusta, which is a key source for white and black truffle called Boda. It is also known as the black gold of the sal forest. It sets underground with the onset of early monsoon and is an edible mushroom with high protein, vitamin, and fiber with the low calorific value used by the local inhabitants as delicious food and in the amelioration of heart disease, blood pressure, and stomach disorder. Owing to its tremendous health benefits, the present study deals with the assessment of the protein content, isolation, and identification of fungi associated with boda. The qualitative analysis revealed that black boda contains more protein content than white boda. The quantitative estimation revealed the presence of 0.97 mg/ml and 0.33 mg/ml of protein for 0.2 mg weight of black and white boda, respectively. Further, the boda sample were inoculated on potato dextrose agar and incubated at...

Medicinal plants abound with many phytochemicals that are effective in representing lots of pharmacological activities. The current study aimed at investigating the phytochemical and pharmaco-logical activity of crude methanol extract of Calamus rotang L. (CRME) leaves. The analgesic activity and thrombolytic activity were examined by the acetic acid-induced writhing method, while the clot lysis effect was evaluated by an in-vitro thrombolytic method. From this study, it is stated that the extract (400, 200 mg/kg) reduced abdominal writhing by 31.06% and 44.33% for 200 mg/kg and 400 mg/kg respectively while the standard showed 58.57% of inhibition and increased the pain reaction time in mice when compared to that of the negative control group in tail-immersion test. The extract presented 16.2 ± 1.75% of human blood clot lysis in the thrombolytic experiment. The presence of steroids, saponins, glycosides, cardenolides, flavonoids, carbohydrates, and reducing sugars might have an influence on the pharmacological activity of...

The new asymmetrical tetradentate (ONNO) Schiff base (L) 4-chloro- 2- ((E)- (4- ((E)-((2-hydroxy-5-nitrophenyl)imino)methyl)benzylidene) amino)phenol was prepared by the condensation of terephthalaldehyde with 2-amino 4-chlorophenol and 2-amino 4-nitrophenol in 1:1:1 molar ratio in methanol. The homo binuclear metal(II) complexes were synthesized in ligand to metal ratio 2:2 from the template method. The composition, geometry and binding sites of ligand and its complexes were determined by various studies like Elemental, molar conductance, electronic, magnetic moment, FT-IR, 1H and 13C-NMR, ESI-Mass, EPR, Thermal, and PXRD. The above spectral studies show that the Schiff is a dibasic tetradentate (ONNO), and its metal complexes possess a square planar structure. The biological applications of all compounds were tested for antibacterial, antioxidant, and DNA cleavage, and the final reports reveal high inhibition activity for metal(II) complexes compared to the ligand. The DNA binding activities of Cu(II) complex was observed by electronic absorption method. Antitumor activity of Cu(II) complex was screened for their cancer-inhibiting ability against MCF-7 human breast cancer cells by using the MTT...

Amongst the known coronaviruses, many were responsible for causing disease in humans knowingly from the common cold to acute severe respiratory syndrome. The novel coronavirus, nCoV-2 has been implied to cause increasingly severe damage to public health besides demolishing the global economy with a staggering figure of continuous rise in mortality within the afflicted cases in almost every country on this planet. Owing to the perplexed scenario there are growing challenges involved in the containment of the spread of this novel coronavirus, which is mounting to be numerous and continuous. The battle is still on with this nCoV-2 since it has evolved, presenting with initial flu symptoms in patients affected to atypical pneumonia mimicking a catastrophic disseminated intravascular coagulation stage leading to cardio-respiratory abnormalities thus assuming proportions of mysterious illness to very unusual symptoms encountered in different age groups. The genomic analysis of the nCoV-2 has revealed constant potential mutations with the evolution of different strains, thereby posing numerous challenges to develop an effective vaccine that will hold a...
