Quantitative determination of secondary compounds in populations of Eryngium foetidum L. from India

Eryngium foetidum L. belongs to the family Apiaceae is known as, cilantro or spiny coriander. It is an arom. herb contg. 0.1-​0.95 % of essential oil. The herb is used as a substitute to coriander and contains iron, carotene, riboflavin, calcium, vitamins and a peculiar saponin. It is widely used as food flavoring and seasoning herb for variety of dishes. The present study aims at quant. anal. of total phenols, flavonoids, tannin and vitamin C content present in different ecotypes of E. foetidum collected from Andaman, Darjeeling and Karnataka. The investigations showed that a significant variation in secondary compds. from the three different regions collected. The phenolic content was high in Darjeeling sample whereas, Andaman sample showed high amt. of flavonoids and tannins. The sample from Karnataka was rich in vitamin C content. The study shows that variation in ecotypic condition has lead to the difference in percentage of secondary compd. synthesis
