GC-MS Analysis of Aroma of Medemia argun (Mama-n-Khanen or Mama-n-Xanin), an Ancient Egyptian Fruit Palm
No full textThe fruits of the edible and medicinal Egyptian palm, Medemia argon, were collected from Aswan in Egypt and the essential oil (EO) from fruits and headspace (HS) of the seeds and fleshy mesocarps were analyzed by GC and GC-MS. Results obtained by GC-MS analysis indicated a high variability in the oil and in the headspace from seeds and mesocarps. Sesquiterpene derivatives were the main group of volatiles in the EO from fruits and in the HS from seeds (45.0 and 64.0%, respectively), while oxygenated hydrocarbon derivatives were the main constituents in the HS obtained from fleshy mesocarps (96.5%). The different chemical composition of the headspace obtained from the seeds and mesocarps of M argon can be correlated with the different roles that the different constituents play in the prevention of dehydration of the fruits in the desert region from where the plant was collected

Establishment of in vitro salvia cell biomass for the controlled production of antioxidant metabolites
No full textDietary consumption of foods rich in antioxidants has been gathering increasing support in recent years. The project NUTRASNACK (E.C. F.P.6 contract No FOOD-CT-2005-023044), was developed to increase the antioxidant potential of food snacks. Several Salvia species and genotypes were tested for their total antioxidant content. Three genotypes with the highest antioxidant values were selected (S. officinalis ‘SOF1’, S. officinalis ‘SOF2’, and S. officinalis ‘SOF3’) and leaf explants of in vivo grown plants were cultured on modified MS media supplemented with 2,4-D, Kinetin and NAA in several combinations in order to induce friable callus. Friable green callus developed after five weeks in the presence of medium containing 0.5 mg L-1 2,4-D and 0.5 mg L-1 Kinetin. Callus was transferred several times to the same medium, and after three months, liquid primary cultures were established. After filtration, the synchronized cells grew rapidly and the growth parameters such as viability and growth curve in dry and fresh weight gave the essential information for the management of the cultures. The EC 50 of total antioxidant capacity was evaluated during all the growth phases of calli and suspension cultures
