Rosemary Leaves

Kinetic study of pilot-scale supercritical CO2 extraction of rosemary (Rosmarinus officinalis) leaves

Supercritical fluid extracts of rosemary leaves exhibit potent anti-inflammation and anti-tumor effects.

Supercritical fluid SF-CO2 treatment of Rosemarinus officinalis L. fresh leaves under optimum conditions (80 degrees C at 5,000 psi) yielded 5.3% of extract supercritical fluid extraction (SFE)-80, in which five major active principles were identified by liquid chromatography/mass spectrometry (LC/MS), viz., rosmarinic acid, carnosol, 12-methoxycarnosic acid, carnosic acid, and methyl carnosate...

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...

Subcellular compartmentation of the diterpene carnosic acid and its derivatives in the leaves of rosemary.

The potent antioxidant properties of rosemary (Rosmarinus officinalis) extracts have been attributed to its major diterpene, carnosic acid. Carnosic acid has received considerable attention in food science and biomedicine, but little is known about its function in the plant in vivo. We recently found that highly oxidized diterpenes increase in rosemary plants exposed to drought and high light s...

Rosemary and Peter Grant

of most families. The holistic approach taken by Marshall is a welcome addition to the field, where work of a synthetic nature has been rare. Having access to all information in one place makes it far easier to see parallels in lifestyles and morphology among the diverse groups that make up the order. Flies is not only for keen dipterists, but is also of relevance to experimental biologists as ...
