Nyctanthes arbor-tristis Linn. (Night Jasmine): extraction techniques, phytochemical constituents, and biological impacts of extracts and essential oil

Abstract

Abstract Background Nyctanthes arbor-tristis Linn. is a small, sacred ornamental tree used in prayer. It is renowned throughout India for its aromatic white blossoms. The entire plant was widely used for several health applications particularly root and bark were used to treat fever and cough, respectively. Also, the leaf was used for managing fever and diabetes, and its cholagogue, diaphoretic, and anthelmintic properties. Main text The current review aimed to comprehensively analyze the botanical characteristics, phytochemistry, and pharmacology of N. arbor-tristis essential oil (NAEO) and extracts. Additionally, it wants to emphasize the latest advancements in phytochemistry and pharmacology related to this aromatic plant. Depending on the variety, origin, and plant parts used, the NAEO yield ranged from 0.002 to 0.10% on a dry basis. The NAEO has been investigated in only a few research studies and resulted, in the predominant levels of phytol and methyl palmitate chemical compounds. Furthermore, the NAEO was found to have significant volatile chemical constituents, including geranylgeraniol, phytoene, nonadecane, linalool, and various other miscellaneous chemical components. The plant extracts and NAEO have numerous biological properties, including antioxidant, antimicrobial, anticancer, anti-inflammatory, analgesic, larvicidal, and other miscellaneous activities. Conclusion This paper analyzes and summarizes the diverse research potential associated with N. arbor-tristis. The results of the present study suggested that most of the biological and pharmacological investigations were carried out without including dosage, positive controls, and negative controls. Furthermore, several pharmacological investigations were exclusively carried out using cell lines and animal models. Hence, the following research endeavors aimed at assessing the medicinal properties of NAEO and extracts in human subjects would broaden the scope of its utilization. Graphical abstract
