Morus alba Linn. is a plant with varieties of phytochemicals and commonly known as Mulberry tree or Nuni (in Assamese). Mulberry is a perennial and woody plant, belongs to the family Moraceae consider as a native plant of China. In Assam, the leaves of mulberry tree are out most important in horticulture department for feeding purpose. A literature survey was done out by using key words such as Morus alba, or mulberry tree or phytoconstituents, or pharmacological activities, or ethnobotany on the search engine namely Scopus, Web of Science, Google Scholars, PubMed. The purpose of this article is to forward a solid review about the plant profile, method of extraction, phytochemicals constituents and pharmacological activities in reference to SARS-CoV-2. All the parts of Morus alba are phytochemically rich but highest number can be found in fruits and leaves. Fruits of Morus alba contains various class of phytochemicals such as alkaloids, anthocyanins, stillbenoids, flavones. Owing to presence of this compounds, it exhibits various pharmacological. Its leaves, fruits and root bark containing flavonoids, anthocyanins, alkaloids and stilbenoids, possess various pharmacological properties. Resveratrol is one of the most important compounds found in M. alba which possess SARS-CoV-2 inhibiting potential. Still there are some gaps remain in exploring whole plants parts and successive studies of toxicity.

Among all cereals, oat is considered to be one of the goods consumed in functional grain, nutraceutical, and pharmaceutical components. The review article aims to explore plant profile, phytochemical constituents present in different parts, and potential therapeutic agent which prevents people from different diseases with their respective mechanism of action it also includes toxicity studies, dosage form, marketed formulation, and industrial application. The information on Avena sativa is collected from the different databases available in Science Direct, PubMed, Scopus, and Google Scholar to search for research papers for literature and data. Reviewed information suggests that the A. Sativa is a good source of a range of phytochemicals including lignans, saponin, anthocyanidins, and avenanthramides, which might be directly and/or indirectly linked with beneficial nutraceutical and/or pharmacological effect(s). The review states, that A. sativa is a promising candidate as a functional and/or non-functional food because of various phytoconstituents. The clinical report has described that the utilization of oats can provide several health benefits. However, systematic rational investigations for such indications and safety profiles are yet to be explored.
