nmr metabolic profiling of greek propolis samples,the present study aimed to investigate the metabolic profile, as well as the antioxidant and anti-ageing activities of twenty propolis samples from different regions of greece. chemical profiling of methanolic extracts was investigated using hptlc and 1 h-nmr techniques. their antioxidant activity was evaluated by free radical scavenging.
chemical characterization and antioxidant activity of nine
the importance of antioxidants is an issue intensely discussed due to their multiple health benefits. their use is not restricted only to the pharmaceutical industry, but antioxidants are also added in several food and cosmetic products [49,50]. the study of the antioxidant activity of plant extracts has become routine in laboratory testing.

- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
