Chemical Composition and Antimicrobial Activities of Iranian Propolis
Background: With considering the importance of natural products for their remedial and therapeutic value, this research was aimed to analyze the chemical compositions and antimicrobial activity of four propolis samples from different areas of Iran (Chenaran, Taleghan, Morad Beyg, and Kalaleh) with various climates and flora. Methods: Ethanolic (70% EtOH) and dichlromethane (DCM) extracts of Ira...
متن کاملDetermination of chemical composition of Turkish propolis.
The aim of the present work is to study the chemical composition of Turkish propolis. Propolis samples were collected from different regions of Turkey (Bursa, Erzurum-Askale, Gumushane-Sogutagil and Trabzon-Caglayan) in 1999. Ethanol extracts of propolis (EEP) were prepared for chemical analysis, using gas chromatograph coupled with mass spectrometry (GC-MS). Our findings show that propolis sam...
متن کاملThe chemical composition of pneumococcal C-polysaccharide.
The species-specific C-polysaccharide of the pneumococcus was first described by Tillett, Goebel, and Avery in 1930 (1). The chemical composition was examined by Heidelberger and Kendall (2) and by Goebel et al. (3) ; the latter study showed that the C-polysaccharide contained 4.47% phosphorus, 5.91% nitrogen, 50.6% reducing sugar, 21.8 % hexosamine, and 13.08% acetyl. Detailed information as t...
متن کاملChemical composition and biological activity of a new type of Brazilian propolis: red propolis.
Propolis has been used as a medicinal agent to treat infections and promote wound healing for centuries. The aim of the present study was to test the antimicrobial, antioxidant, and cytotoxic activities of a new type of Brazilian propolis, popularly called red propolis, as well as to analyze its chemical composition. The antimicrobial activity against Staphylococcus aureus ATCC 25923 and Staphy...
متن کاملChemical Composition and Botanical Origin of Red Propolis, a New Type of Brazilian Propolis
Red propolis is a new type of Brazilian propolis. This material, as well as the secretions of 20 plant species that are often mentioned as its probable botanical source, have been investigated by RP-HPTLC. Phytochemical evidence based on UV-VIS spectra, RP-HPLC and GC-MS, showed Dalbergia ecastophyllum (L.) Taub. to be the main source of red propolis in Alagoas state. The propolis and plant res...
