In terms of pharmacognosy, asafoetida is comprised of a number of active chemicals, the most notable of which are coumarins, volatile oils (17%), and ferulic acid (60%). Ferulic acid and coumarins (40%) are two of the components that contribute to the medicinal value of this plant. The volatile oils are responsible for the strong odour and flavour of this plant. It is used for a variety of applications in the medical field. It is not only used as spices and condiments for the goal of imparting taste in curries, but it is also utilised in the treatment of gastrointestinal tract diseases, asthma, whooping cough, hypertension, and a variety of other conditions. The herb has been used to extract a variety of phytochemical components, including sesquiterpene coumarins, coumarins, diterpene coumarins, and chemicals containing sulphur.

As a result, there is a tremendous need to seek out new means of producing reliable medications to meet the rising demand of a global populace suffering from a wide range of health problems. Various resources are available in marine habitats for the development of novel medications. Their life circumstances are radically different from those found in a terrestrial setting. In order for marine animals to thrive in the ocean, they produce a variety of secondary metabolites, which can possibly be life-saving bioactive compounds that come from an increasing variety of marine microorganisms. These metabolites have pharmacological properties that make them intriguing as a potential for human medications. Therefore, there has recently been a rise in interest in marine-derived biomolecules as potential treatments. Utilizing a wide range of screening methods, we can investigate the effects of these extracts and purified compounds from marine organisms in the medicinal industry, such as cancer prevention, inflammation reduction, virus and bacteria inhibition, ion channel/receptor modulation, and plant growth stimulation. The structures of bioactive substances will be determined after they have been isolated chromatographically. Marine-based bioactive compounds can be (semi) synthesized to make new derivatives, structural analogues, and copies that can be used to build new marine-based chemical catalogs and contribute as lead or hit molecules.
