The Zingiberacea or ginger family is a family of flowering plants comprising roughly 1,600 species of aromatic perennial herbs with creeping horizontal or tuberous rhizomes divided into about 50 genera. The Zingiberaceae are distributed throughout tropical Africa, Asia, and the Americas. Many members are economically important as spices, ornamentals, cosmetics, traditional medicines, and/or ingredients of religious rituals. One of the most prominent characteristics of this plant family is the presence of essential oils in particularly the rhizomes but in some cases also the leaves and other parts of the plant. The essential oils are in general made up of a variety of, among others, terpenoid and phenolic compounds with important biological activities. The Republic of Suriname (South America) is well-known for its ethnic and cultural diversity as well as its extensive ethnopharmacological knowledge and unique plant biodiversity. This paper first presents some general information on the Zingiberacea family, subsequently provides some background about Suriname and the Zingiberacea species in the country, then extensively addresses the traditional uses of one representative of the seven genera in the country and provides the phytochemical and pharmacological support for these uses, and concludes with a critical appraisal of the medicinal values of these plants.

Aim: Calendula suffruticosa ssp. suffruticosa Vahl, Medicinal and Aromatic plant, spontaneous and widespread in the Mediterranean region and in the Northeast of Algeria, is widely used by the local population for its medicinal properties. Methods: The chemical composition of the ethanolic extract of Calendula suffruticosa was established for the first time using GC / MS. The antioxidant activity of the ethanolic extract was evaluated in vitro by the DPPH (2,2-diphenyl-1-picrylhydrazyl) test, the FRAP assay and \β-carotene bleaching assay. Results: sixty-four compounds are identified by GC/MS analysis, six are predominant: \α-linoleic acid (24.20\%), linoleic acid (23.58\%), Stigmasterol (8.53\%), 2-Metyl-Z-4-tetradecene (6.62\%) And \α-Bisabolol (1.70\%). The free radical scavenging by DPPH method indicated that the ethanolic extract of C. suffruticosa showed a very high antioxydant activity with an IC50 = 0.017 \± 1.00 mg / ml. This extract also showed an ability to reduce very high iron with a maximum optical density of 1.157 at a concentration of 0.5 mg / ml and an antioxidant activity compared to the \β-carotene / linoleic acid test of order of 75 \± 1.02\%. Conclusion: These results show for the first time the richness of phytochemicals and the strong antioxidant activity of the species Calendula suffruticosa endemic to north-east of Algeria.
