Item A GLIMPSE ON Baccaurea accaurea ramiflora, ramiflora, A LESS APPEALING, UNDERUTILIZED MEDICINAL PLANT OF WEST WEST-BENGAL (AN EXTENSIVE REVIEW)(INTERNATIONAL JOURNAL OF CURRENT RESEARCH, 2025-01-04) Dey, Purnima; Pal, ImanaBaccaurea ramiflora Lour. syn. Baccaurea sapida (Roxb.) Muell. Arg locally known as Latkan or Anshfol is a versatile though underexploited plant with number of health benefits. In West Bengal the fruit plant is grown mainly in homestead condition. It is a mild acidic fruit and mainly consumed fresh. This extensive extensive review encompasses all the available literature with respect to habitat, physical characteristics, ethenomedicinal and traditional uses, physiochemi physiochemical and nutritional composition, active constituents ,therapeutic role which helps to put a glimpse on this underutilized less appealing medicinal plant of West-Bengal.Item A Review on Lotus (Nelumbo nucifera) Seed(International Journal of Science and Researc, 2025-01-04) Pal, Imana; Dey, PurnimaNelumbo nucifera or lotus seeds are edible and have been used as a traditional medicine since ages for curing various diseases. The longevity of lotus seed is unique. Researches revealed that it has hepatoprotective, hypoglycemic, immunomodulatory, antianalgesic, antiperkinsonian, antifertility, antidermatophytic, psychopharmacological properties. It can be used as low cost protein and energy supplement. Lotus seed oil is also useful. It is used in different cuisines. This review attempts to cover all the available literature on the seeds of Nelumbo nucifera with respect to its traditional uses, chemical constituents, physicochemical properties, phytoconstituents and summing up of its various physiological, psychological and therapeutic benefits.Item A stimuli-responsive L-DOPA-based supramolecular gel for the detection of fluoride ion(Royal society of chemistry, 2024) Mandal, Subhra Kanti; Seth, Piya; Kar, TanmoyItem Active components of tea (Camellia sinensis) extracts and their beneficial application on human health(2024-12-30) Seth, Piya; Mandal, Subhra KantiTea is one of the most frequently consumed beverages across the world and is popular for its classic brew, flavour and wide range of health benefits. The variation in aroma, taste and colour of different kind of teas are caused by the manufacturing process popularly known as fermentation and essentially determine the quality and acceptance of tea flushes. A variety of volatile components such as terpenoids, alcohols, carbonyl compounds, etc. are reported to contribute to the signature tea aromas whereas the non-volatile polyphenolic components (mainly catechins, flavonols, theaflavins, thearubigins), amino acids and xanthines are responsible for the characteristic taste and colour of tea infusions. The nutritional value of tea is mostly gained from the tea polyphenols and amino acids that are reported to possess a broad spectrum of bioactivities, including anti-oxidant properties, reduction of various cancers, inhibition of inflammation and protective effects against diabetes, hyperlipidemia and obesity. Global tea research has generated much in vitro and in vivo data rationally correlating tea polyphenols with their preventive and therapeutic properties against human diseases like cancer, metabolic and cardiovascular diseases etc. Recently, number of studies also suggests that tea polyphenols have the potential to treat or prevent COVID-19 disease. In the current review, we focus on the chemistry behind the signature fragrance, taste and colour of variety of tea and their beneficial account as antioxidant and therapeutic effectiveness against many diseases such as lowering of blood pressure, diabetes, inflammation, anticancer properties and most interestingly against COVID-19 pandemic. Keywords: Tea chemistry, polyphenols, catechins, theaflavins, health benefits, COVID-19.Item An Extensive Review on Allium ampeloprasum A Magical Herb(International Journal of Science and Research, 2025-01-04) Dey, Purnima; Khaled, Kazi LaylaAllium vegetable has been used as folk medicine since ancient times. Allium genus has over 600 members which differ in maturing, color and taste; however, they are similar in biochemical content. Allium ampeloprasum, is a monocotyledon plant of the lily family (Liliaceae) and belongs to the genus Allium. It has a characteristic taste and morphological features, making it to be considered as one of the popular herbal medicine. A scrutiny of literature revealed some notable pharmacological activities of the plant such as antidiabetic, hypolipidaemic, antimicrobial, free radical scavenging and anti-inflammatory role. This review attempts to encompass the available literature on Allium ampeloprasum with respect to its pharmacognostic characters, ethanobotanical and traditional uses, chemical constituents and summary of its various pharmacological activities and clinical effectsItem An overview of the effect of anionic coligand on structure and magnetic properties of some homometallic NiII and heterometallic NiII-MnII complexes of Schiff base ligands(ELSEVIER, 2024) Mandal, Subhra Kanti; Seth, PiyaHomometallic NiII-Schiff base complexes with various anionic coligands have been widely studied for their structural diversity, catalytic and magnetic properties. Introduction of MnII as heterometal in these complexes is very much challenging to the synthetic and magneto-chemist as MnII possesses higher number of unpaired electrons in high spin ground state. Thus in NiII-MnII heterometallic polynuclear complexes spin–spin interaction and easy axis type magnetic anisotropy can lead to ferromagnetism, antiferromagnetism, ferrimagnetism, etc. In this dissertation we have discussed the synthetic strategies, structural features and magnetic properties of 20 homometallic NiII complexes and 13 heterometallic NiII-MnII complexes derived from some tridentate (N2O), tetradentate (N2O2) and hexadentate (N3O3) Schiff base ligands and various terminally coordinating or bridging anionic coligands (carboxylate, nitrate, nitrite, azide, thiocyanate, dicyanamide etc.). The profound role of anionic coligand in mediating phenoxido bridging angles and hence magnetic behavior of these complexes is also been highlighted.
