Antidiabetic properties of Linum usitatissimum L. seed: A promising medicinal plant
(Academic Press, 2023) Sarfraz, Haram; Ahmad, Iffat Zareen
Herbal medicine has grown exponentially in popularity over the last several years, garnering favor in both developed and developing countries due to its natural origin and absence of negative effects. Medicinal herbs have been existing as a rich yet untapped source of antidiabetic agents, despite the fact that they have been used to cure diabetes mellitus since early times. Linum usitatissimum L., or flaxseed, is a rich source of antioxidant and antidiabetic phytochemical compounds such as lignans, phenolic acids, and flavonoids and hence has a significant potential for lowering the incidence and delaying the development of diabetes in humans.
Linum usitatissimum L.: Rich Storehouse of Pharmacologically Active Metabolites in Indian Traditional Medicine
(Springer, 2023) Sarfraz, Haram; Ahmad, Iffat Zareen
Indigenous traditional medicines in India use a lot of plant ingredients and their derivatives. Linum usitatissimum L. commonly known as ‘Alsi’ or ‘Tisi’, in India or ‘Flax’ in English, is one such pharmacologically rich plants. Phytochemicals (e.g.: phenolic acids, lignans, and flavonoids) are found naturally in Linum usitatissimum. While scientific data support flaxseed eating, a sizable portion of the public remains uninformed of the advantages and potential uses. The present chapter summarizes the available information on the traditional uses of Linum usitatissimum L. and its pharmacologically active natural constituents.
Regulation of Photosynthetic and Respiratory Cycles and Nitrogen Assimilation in Higher Plants and Microalgae by Melatonin
(CRC Press, Taylor & Francis Group, 2023) Sarfraz, Haram; Ahmad, Iffat Zareen
Melatonin is assumed to have originated in bacteria, as it has been discovered in both proteobacteria and photosynthetic cyanobacteria. Melatonin promotes the immune system in plants, altering circadian cycles and leaf stomatal closure. Melatonin is a multifunctional chemical found in plants and microalgae. It primarily functions as an antioxidant. Melatonin scavenges reactive oxygen species and reactive nitrogen in plants and microalgae, protecting them from cellular damages. Melatonin is also involved in the germination, growth, rooting, photosynthesis, respiration, and nitrogen assimilation of plant seeds. Melatonin influences lipid synthesis in microalgae under nitrogen stress. Abiotic stress produced by the activation of antioxidant enzymes has been overcome by the exogenous melatonin treatment in microalgae, which eradicates the reactive oxygen species produced, thus playing a role as an effector molecule. Due to the presence of circadian rhythms endogenously in some species of plants, melatonin played a central role in the regulation of the day-night cycle. This chapter deals with understanding the regulatory role of melatonin in photosynthesis, respiration, and nitrogen assimilation in plants and microalgae in detail. More specifically, our knowledge escalates towards the role of melatonin in physiological studies in plants and microalgae and their future prospects.
