The occurrence of cumarins
and sterols in tissue-cultures of roots of Anethum graveolens and Pimpinella anisum (author's transl).
The phytochemical analysis of the dried seed extract of fenugreek has been reported to show the presence of proteins, vitamins, flavonoids, terpenoids, carotenoids, cumarins
, curcumins, lignin, saponin and plant sterol (Bukhari et al., 2008).
The presence of various secondary metabolites viz., alkaloids, quaternary alkaloids, cumarins
, flavanoids, steroids / terpenoids, phenolics etc with potential anti-fungal activity were reported in various plant extracts (Alice,1984; Aswal, et al.,1984; Abraham et al., 1986; Chopra et al., 1992).
Phytochemical tests were conducted to investigate the presence of alkaloids, saponins, tannins, quinones, flavonoids, triterpenes, steroids, heterosides and cumarins
. The specific qualitative tests were based on the visual observation of change in color or formation of precipitate after addition of specific reagents (MATOS, 2009).
2013), the occurrence of cumarins
content in Glucevia[R], including fraxin, fraxetin, esculin, esculetin, cichoriin, scopolin and fraxidin glucoside was quantified.
