Chemical compounds from Phoenician juniper berries (Juniperus phoenicea)

Abstract

Natural chemical compounds are a widely researched topic worldwide because of their potential activity against cerebrovascular diseases. Chemicals from Juniperus phoenicea berries are reported in this study. Lipids (11%) from seeds are mainly unsaturated (86%). Minerals are also quantified like Na (63.8 mg per 100 g DW) or K (373.9 mg per 100 g DW). Total reduced sugars are ca 192.6 mg g⁻¹ DW. Polyphenols and flavonoids from berries are highly present with an average of 1764 ± 174.3 mg gallic acid per 100 g DW and 890 ± 47.6 mg rutin per 100 g DW, respectively. Mean free radical scavenging activities, determined by DPPH and ABTS, are 1337 ± 126.2 mM TEAC per 100 g DW and 1105.7 ± 95.9 mM TEAC per 100 g DW, respectively. All findings improve the possible presence of biologically active fractions in phytocomplex that could be used as such and/or extracted for the formulation of supplements and/or ingredients for the pharmaceutical industry.
