EDITORIAL

Addressing the challenges of feeding the increasing world population is the primary concern mankind faces. In the era of abrupt changes in climate and increasing environmental pollution, it has been difficult to sustain the production of safe and secure food crops. Therefore, the plant science community's intent demands a significant thrust to secure the future of the upcoming generation by devising strategies for improving plant growth and productivity. In this context, the journal strives to publish relevant works of high scientific merit and advances the knowledge of the growing scientific community.

The NBU Journal of Plant Sciences (NBUJPS) is an international peer-reviewed journal published by the Department of Botany, University of North Bengal, since 2007. It gives the platform for publishing top-notch research on various topics in plant science, animal-plant interactions, microbiology, food safety and security, plant disease management, plant breeding, environment and ecology, and many more.

The journal's editorial board publishes high-calibre articles in print and online (https://njps.nbu.ac.in/) in one volume each year. The NBUJPS has officially registered for membership in CrossRef. All the articles are assigned unique DOI numbers and include other CrossRef services like similarity checking and reference linking. It gives me extreme pleasure to inform you that the NBUJPS publishes all the articles free of charge. All the articles are published following the open-access policy and are completely free to read and download.

We are delighted to inform you that volume 15 has been published, including reviews and research papers. This volume includes articles on the effect of air pollution on plant growth, stress responses of plants, including local rice cultivars, effective use of plant growth promoting rhizobacteria and plant extracts in disease management, cultivation and utilization of exotic pumpkin and underutilized fruits for food security, exploration of the lichens of Himalaya, and so on. These articles were contributed by numerous senior professors, scientists, and junior researchers from various institutions. The articles in this issue cover a broad spectrum of recent advancements in both basic and applied fields of plant science research, and they are all very important. This volume will significantly benefit all scientists and researchers working in various plant science sectors regarding contemporary breakthroughs and need-based research.

    Assessment of Therapeutic Potential and Phytochemical Profiling in Different Solvent Extracts of Centella asiatica
    (University of North Bengal, 2023) Saran Kumar Gupta
    Centella asiatica (L.) Urban, commonly known as Indian pennywort, a small perennial herb from the Apiaceae family has been used in traditional medicine for thousands of years. This study aimed to evaluate the effect of different extraction solvents on the therapeutic and phytochemical profiles of various parts of Centella asiatica. Among the various plant parts assessed, the leaves exhibited the best antioxidant and in vitro antidiabetic activity and the highest amount of phytoconstituents compared to petiole and root. Methanol was identified as the most effective solvent, yielding optimal IC50 values for DPPH (30.65 μg/ml) and ABTS (45.23 μg/ml). Additionally, the methanolic extract of leaves exhibited highest content of phenolics (65.49 mg GAE/g DW) and flavonoids (12.56 mg QE/g DW). The methanolic leaf extract also demonstrated a promising inhibition potential against α-amylase and α-glucosidase enzymes and possessed elevated levels of alkaloids, glycosides, tannins and terpenoids. This study demonstrated significant variations in the therapeutic potential of Centella asiatica, attributed to differences in the nature of the extraction solvents.

    Underutilized Fruits of Northeast India and its Potential Benefits on Human Health - Review
    (University of North Bengal, 2023) Banerjee, Swarnendra; Sen, Arnab
    The Indian Himalayas, a global biodiversity hotspot, is home to 2532 species from temperate regions of Europe, China, Burma, the Sahara, and Africa. India's plant biodiversity includes 21 agroecosystems, including farmed fruit and wild, under-utilized fruit crops. These underutilized fruit crops have potential but are rarely planted, infrequently available on the market, or not farmed commercially. They are disease-resistant and adapted to heat and cold extremes, blessing tropical nations like India. Underutilized fruit crops have medicinal properties and are often used by Native Americans to heal ailments and for the financial well-being of tribal people in rural regions. The use of wild fruits as nutritional supplements or less expensive alternatives to commercial fruits is growing worldwide. Identifying and utilizing underutilized species is crucial for a diverse and nutritious diet, especially for rural poor and socially vulnerable populations in emerging countries. India's North-Eastern Hill region is an agrobiodiversity hub characterized by diverse ethnic and cultural backgrounds. It is rich in wild agricultural plant relatives, particularly underutilized fruit crops, and mixed temperate, tropical, and subtropical fruits from various genera. Fruits, vegetables, and other plants naturally produce important polyphenol metabolites that influence their sensory and nutritive qualities, potentially curing various conditions.
