진달래 화분의 다양한 이용성과 기능성에 관한 연구를 위한 기초연구의 일환으로 추출조건별 이화학적 특성을 조사하였다. 페놀성 화합물과 DPPH에 의한 전자공여능은 물보다 80%에탄올이 우수하였으며, 용매비에 따른 페놀성 화합물과 전자공여능은 용매비가 20배에서 높은 것으로 나타났다. 추출온도에 따른 페놀성 화합물은 에서 347.60 mg%로 높게 나왔으며, 전자공여능은 에서 67.93%로 높게 나타났다. 추출시간에 따른 페놀성 화합물의 추출물은 6

The physiochemical properties of Rhododendron mucronulatum pollens were examined after the use of various extraction conditions. The levels of phenolic compounds and electron donating abilities (DPPH) were better after 80% (v/v) ethanol extraction than after water extraction. The content of phenolic compounds and the DPPH were high when the solvent ratio was 20X. The content of phenolic compounds was highest at (347.60 mg/100 g). The DPPH was highest, at 67.93%, when extraction was performed at . An extraction time of 6 hr yielded the highest content of phenolic compounds (312.63 mg/100 g). The DPPH did not vary with extraction time. Both the levels of phenolic compounds and DPPH values rose when extractions were performed twice. In summary, a solvent ratio of 20X, an extraction temperature of , double extraction and an extraction time of 6 hare optimal for extraction, with maximal DPPH and phenolic content, of Jindalrae pollens.
