Phytochemical studies on celery and garden rocket seeds [electronic resource].

Includes references.

From ancient time celery (Apium graveolens) and garden rocket (Eruca Sativa, Mill) are used in traditional medicine. The seeds of these plants were conducted to separate and qualitative identify their active components. (i.e., alkaloids, flavonoids, terpenes, saponins, polyphenols, ... etc.,). The seeds were extracted with methanol which considered the mother liquor. The later solvent extract was subjected to successive extraction with solvents increased in their polarity started with pet. Ether followed by chloroform and ethyl acetate. Effects of three celery seeds extracts as antimicrobial activity against different strains of pathogenic fungi were studied. The resulted rocket and celery seeds extracts were used also as natural antioxidants. The antioxidant power of these extracts was measured by different methods. The ethyl acetate extract of celery seed when used as antioxidant was more effective than ethyl acetate extract of rocket seed and artificial antioxidant BHT. The phenolic compounds were extracted and identified by HPLC in both rocket and celery seeds. The phenolic compounds in rocket were: phenol, gallic acid, dadzin, genstin and p-OH benzoic acid. Celery seed were distinguished with phenolic compounds of salicylic acid, phenol, quercetin, catechine and rutin. Caffeic acid, quercetin and vanillin disappeared in rocket seed, while cinnamic acid, euganol and pyrogallic disappeared in celery seed. Generally, these phenolic compounds in both two plants have important effects as natural antioxidants.
