COMPARATIVE STUDY BETWEEN ANISE SEEDS AND MINT LEAVES (CHEMICAL COMPOSITION, PHENOLIC COMPOUNDS AND FLAVONOIDS)

Abstract

The objective of research was to study the chemical composition , phenolic compounds and flavonoids of powder from anise seeds and mint leaves. Anise seeds contains: total carbohydrates 51.4 %, crude protein 18.1 %, total lipids 13.7 % and total ash 14.9 % in dry sample. While mint leaves contains contains total carbohydrates 55.7 %, crude protein 19.8 %, total lipids 4.9 %, and total ash 18.6 % in dry sample. Total phenolic in anise seeds were 216.6-237.8 mg/100g in aqueous and ethanolic extracts, respectively and total flavonoids were 148.1-156.4 mg/100g in aqueous and ethanolic extracts, respectively comparing with 234.3-278.9 mg/100g in aqueous and ethanolic extracts, respectively and 157.5-186.3 mg/100g in aqueous and ethanolic extracts, respectively of total phenolic compounds and flavonoids in mint leaves. HPLC results showed that anise seeds were found to contain 19 of phenolic compounds, amoung them catechein, cinnamic, ellagic, gallic, chlorogenic, ferulic and catechol were the major active in anise seeds, while mint leaves contained rosmaric, cinnamic, gallic, ferulic, and savianolic as the major of phenolic compounds. In conclusion the obtained results found that, anise seeds and mint leaves extracts were rich in secondary metabolites (phenolic compounds and flavonoids) with high nutritional and health values.
