Conventional and Enzyme-Assisted Extraction of Rosemary Leaves (Rosmarinus officinalis L.): Toward a Greener Approach to High Added-Value Extracts
نویسندگان
چکیده
The effect of different extraction methods rosemary leaves on the total phenolic content (TPC), and antioxidant activity extracts was herein investigated. Firstly, solid-liquid conventional (CEM) microwave-assisted (MAE) were implemented in an effort to identify solvent microwave irradiation extract quality. obtained from CEM at room temperature, using ethanol/water 95:5 v/v, showed highest (IC50 = 12.1 ?g/mL). MAE 50:50 v/v provided with TPC DPPH radical scavenging ability a significantly shorter time (1 h for 24 CEM). Enzyme-assisted (EAE) five commercial enzyme formulations implemented, kinetic equation calculated. Finally, EAE as pretreatment method examined. Pretreatment plant material pectinolytic enzymes 1 prior 50% hydroethanolic found be optimum conditions leaves, providing higher 14.3 ± 0.8 ?g/mL) (15.2 0.3 mgGAE/grosemary) than corresponding without pretreatment.

Antioxidant and antimicrobial activity of extracts obtained from rosemary (Rosmarinus officinalis) and vine (Vitis vinifera) leaves
The antioxidant properties and antimicrobial activity of rosemary extracts were compared to those of vine leaf extracts. The phenolics were quantified by HPLC. Rosemary extracts were stronger in reducing power than vine leaf extracts but possessed weaker superoxide anion radical (O2 ) scavenging capability. The antimicrobial activity was confirmed by the broth microdilution test using minimal i...

Antimicrobial activity of rosemary extracts (Rosmarinus officinalis L.) against different species of Listeria
Reduction or elimination of chemically synthesized additives from foods is a current demand in food industry. A new approach to prevent the proliferation of microorganisms or protect food from oxidation is the use of essential oils or plant extracts as natural additives in foods. We have studied antimicrobial activity of rosemary extracts (Rosmarinus officinalis L.) against different species of...
متن کاملAnticancer Effects of Rosemary (Rosmarinus officinalis L.) Extract and Rosemary Extract Polyphenols
Cancer cells display enhanced growth rates and a resistance to apoptosis. The ability of cancer cells to evade homeostasis and proliferate uncontrollably while avoiding programmed cell death/apoptosis is acquired through mutations to key signaling molecules, which regulate pathways involved in cell proliferation and survival. Compounds of plant origin, including food components, have attracted ...
