  • A direct HPLC method was used to analyze determination of resveratrol in grapes and wines. Content of resveratrol in different parts of 13 grape cultivars and 13 wines were quantified. The average total resveratrol content was $143.5{\mu}g/g$. Resveratrol contents in the skin, fruit, seed and fruit stem were distributed range of $0.9{\sim}104.8{\mu}g/g,\;0.1{\sim}0.5{\mu}g/g\;1.7{\sim}173.9{\mu}g/g\;2.9{\sim}247.4{\mu}g/g$, respectively. Resveratrol contents in 13 wines were distributed range of $253.3{\sim}11,271.6{\mu}g/g$.

  • A simple method for identifying of ectomycorrhizal fungi was presented, using the polymerase chain reaction (PCR) to amplify the ITS (Internal transcribed spacer) regions of the nuclear ribosormal repeat. The sequences analyzed 6 species, Pisolithus tinctorius, Chroogomphus rutilus, Leucogyrophana pinastri, Suillus granulatus, Lactarius laeticolorus, and Suillus bovinus at hongreung forest, and analysed 10 species, Craterellus lutescens, Thelephoroid mycorrhizal, Lactarius quieticolor, Tricholoma matsutake, Lactarius chrysorrheus, Sarcodon aspratus, Russula versicolor, Suillus luteus, Tricholoma terreum, and Amanita vaginata at hongcheon forest. Finally, the amplification by PCR with ITS1-ITS4 primers offers good results over classical identification for ectomycorrhizal fungi species.
