Determination of Phenolic Compounds in Pinus eldarica by HPLC
Authors
Abstract:
Background: The antioxidant components have been identified in some pine species. Antioxidant properties of proantocyanidins reduce free radicals induced by DNA fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. Objective: In this study, we analyzed different parts of Pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. Methods: Pine specimens were collected from four different geographic locations in Tehran. The HPLC method (UV detector, C18 reverse phase column, 4.6 mm (25 cm, and water/ H3PO4/ methanol/ acetonitril as eluant) were employed for evaluating total polyphenols. The wavelength for detection of polyphenolic compounds was 280 nm in this study. Results: The highest range of total polyphenols was detected in the bark of this pine, specially reported a considerable amount of tyrosol in Pinus eldarica. Tyrosol stimulated resistance to oxidative stress and also has anti aging effect. Conclusion: The high amount of total phenolic compounds in P. eldarica bark might be attractive for future research considering its health benefits.

full textPhytochemical analysis of Pinus eldarica bark
Bark extract of Pinus pinaster contains numerous phenolic compounds such as catechins, taxifolin, and phenolic acids. These compounds have received considerable attentions because of their anti-inflammatory, antimutagenic, anticarcinogenic, antimetastatic and high antioxidant activities. Although P. pinaster bark has been intensely investigated in the past; there is comparably less information ...

Three spectrophotometric methods were evaluated in order to determine total phenolic compounds content in propolis from Tucumán, Argentina; applying the Folin-Ciocalteau, Prussian blue and ophenanthroline methods. The Prussian blue method was the most sensitive one although it was also unstable. The o-phenanthroline method may be more reliable and proved to be quite sensitive and stable. FolinC...

full textFingerprint analysis and simultaneous determination of phenolic compounds in extracts of Curculiginis Rhizoma by HPLC-diode array detector.
Curculiginis Rhizoma (Curculigo orchioides GAERTN.) is a well-known Chinese herbal medicine, as well as an important Rasayana drug in India. Current criteria of quality control on this herb are to quantitatively analyze single compound curculigoside, which fail to comprehensively evaluate quality of this herb. In this paper, a simple and reliable HPLC coupled with diode array detector (DAD) met...
