Salt-tolerant plants grow in a wide variety of saline habitats, from coastal regions, salt marshes and mudflats to inland deserts, salt flats and steppes. Halophytes living in these extreme environments have to deal with frequent changes in salinity level. This can be done by developing adaptive responses including the synthesis of several bioactive molecules. Consequently, several salt marsh plants have traditionally been used for medical, nutritional, and even artisanal purposes. Currently, an increasing interest is granted to these species because of their high content in bioactive compounds (primary and secondary metabolites) such as polyunsaturated fatty acids, carotenoids, vitamins, sterols, essential oils (terpenes), polysaccharides, glycosides, and phenolic compounds. These bioactive substances display potent antioxidant, antimicrobial, anti-inflammatory, and anti-tumoral activities, and therefore represent key-compounds in preventing various diseases (e.g. cancer, chronic inflammation, atherosclerosis and cardiovascular disorder) and ageing processes. The ongoing research will lead to the utilisation of halophytes as a new source of healthy products as functional foods, nutraceuticals or active principles in several industries. This contribution focuses on the ethnopharmacological uses of halophytes in traditional medicine and reviews recent investigations on their biological activities and nutraceuticals. The work is distributed according to the different families of nutraceuticals (lipids, vitamins, proteins, glycosides, phenolic compounds, etc.) discussing the analytical techniques employed for their determination. Information about the claimed health promoting effects of the different families of nutraceuticals is also provided together with data on their application.

“…Following noteworthy attempts at screening endemics for their biological activity stand out: Antimicrobial and insecticidal activities of Sri Lankan plants were carried out by scientists from the University of Peradeniya; of particular importance are the work on endemics (Hewage et al, 1998;Kumar et al, 1989;;Bandara et al, 2015). In addition, biological activity of Sri Lankan lichens have also been determined (Thadhani et al, 2012).…”

Ethnomedicine evolved from the traditional use of plant parts for treating various ailments. Historically, most medical breakthroughs have arisen based on the plant sources showing potential for curing many diseases. Even so, the therapeutic power and scientific validation of their modes of action remains unexplored. Sri Lanka being a biodiversity hotspot due to its high endemism and diversity has inspired the search for ethnopharmacological values which may give rise to drug leads or to the discovery of new bioactive compounds. This brief review aims to highlight the global importance of the exploration of traditional medicinal plants, current status and the progress of the studies on Sri Lankan medicinal plants, and the necessity to discover the medicinal value of the Sri Lankan plants.

“…Among the lower plants such as lichens, the recent reports of new species being discovered frequently indicate that their diversity may be as high as the higher plants (Orange et al, 2001). Sri Lankan plants have been tested for biological activity with promising results (Hewage et al, 1998). In addition, the structural diversity among Sri Lankan higher and lower plants are typified by the discovery of, alkaloids, (Puvenendran et al, 2008), compounds with iron chelating function (Sahib et al, 2008;Kathirgmanathar et al, 2006;Karunaratne et al, 1992;Kumar et al, 1989), and phenolic acids and ketones (Kumar et al, 1990), all possessing a variety of bioactivities.…”
