In order to compare the variation of Korean native Yea plants, the botanical specimens of the two introduced varieties and the wild varieties collected from 49 places were made. The leaf and flower types from them were investigated. 1) About 78% of the wild tea `plants were existed in hamboo thicket or in forest, and 95% were grown in the southward inclined place. 2) The wild tea plants were distributed in the region from 34°27` north to 35°43` north of latitude, but most of them were grown in the region of 35 degree north of latitude. 3) The leaf types of wild tea plants were elliptical and oblong, but onr oval type of leaf was found in the Mando¨ksa, Kangjin. 4) The Leaf sizes of wild tea plants were 14.74 0.57 × 5.72 ± 0.24㎝ in the large leaf and 12.16 1.57 × 3.53 0.41㎝ in the small leaf. 5) There were two leaf types that one is acuminate, coriaceous, reticulate, dark green, and the other is obtuse, chartaceous, rugose, deep green. 6) There were not much difference between varieties in the flower types, only except the trait of Yongjang. 7) Among the wild tea plants, it was considered that Yongjang-type variety would he a variant or hybrid of bohea-variety (chinese-variety) and Waun-type variety would he a variant or hybrid of macrophylla variety and General-type variety would be a degenerated variant of Waun-type or another hybrid.
열풍건조와 동결건조에 따른 수창포(Acorous calamus L.) 분말의 부위별 이화학적 특성
은종방,범희주,강대진,이병두,손진한,임지순 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.11
The physical and chemical characteristics of powders from hot air and freeze dried leaves and roots of Acorous calamus L. were investigated. Two parts, upper and lower, of leaves, and two kinds of roots, 4 and 6 years old, were dried at 30 and 40oC, freezedried, and ground to make powder. Contents of moisture, ash, crude fat, and crude protein in freeze dried powder of upper leaf were 4.87%, 6.73%, 2.22%, and 3.57%, respectively. Water absorption index (WAI) and water solubility index (WSI) in freeze dried powder of lower and upper leaves were 8.476 and 0.077 g/mL. Contents of chlorophyll a, chlorophyll b and total chlorophyll in freeze dried powder of upper leaves were 12.18, 16.86, and 29.11 mg/100 g, respectively. Contents of total and reducing sugar in freeze dried powder of 4 and 6 years roots were 111.89~119.21 ppm and 5.02~5.22 ppm, 109.92~114.65 ppm and 5.21~5.32 ppm. Contents of total polyphenols and flavonoids in freeze dried powder of upper leaf were 125.02 and 21.02 μg/mg, respectively. 수창포의 부위별 건조조건을 달리한 분말의 일반성분, 당 및 클로로필 등을 분석 검토하였다. 각 부위별 수분의 함량은 모두 온도가 증가할수록 낮았고, 동결건조를 실시한 시료가 가장 낮았다. 회분함량은 온도가 증가할수록 같거나 높아졌으며 동결 건조한 시료의 함량이 가장 낮았다. 조지방과 조단백 함량은 각 부위별 건조방법에 따라 유의적 차이가 없었다. 색도 중 잎의 품질특성에 중요한 a*값은 잎상부가 하부에 비하여 a*값이 낮아 품질 면에서 우수하였다. 클로로필 함량 역시 잎상부가 하부에 비하여 함량이 높았다. 환원당함량은 뿌리에 높았으며, 특히 40oC 열풍 건조한 시료가 가장 높았으며, 총당 함량은 건조조건별로 차이가 없었으며 잎상부가 가장 높았다. 총 폴리페놀은 창포의 잎에서 상당히 높은 함량은 보였으며, 건조조건에 따라서 유의성 검정 결과 큰 차이는 없었지만 잎이 뿌리보다 상당히 높은 함량은 나타내었다. 총 플라보노이드는 뿌리와 잎에서 고른 분포를 나타내었으나 잎상부가 더 높은 함량을 나타내었다. 위의 결과로 시료의 품질저하를 막기 위해서는 동결건조를 실시하는 것이 유리할 것으로 생각된다.
