포황을 기능성 식품의 소재로 이용하기 위한 가능성을 검토하기 위하여 일반 성분, 유리 당, 유리 아미노산, 지방산 조성, flavonoid 등을 분석하고 생리활성을 측정하였다. 포황의 일반성분은 수분 12.7-13.2%, 조단백질 15.7-17.8%, 조지방 1.3%, 유리당 7.5-7.7%, 조섬유 14.7-18.6%, 회분 3.4-4.9%, 가용성 무질소물 49.7-55.9%이었다. 유리아미노산 함량은 애기부들이 1.923 %, 좀 부들이 0.907 %, 큰 부들이 0.333 %로서 품종 간에 큰 차이를 나타내었고 그 조성은 모든 품종이 GABA alanine, glutamic acid, proline의 순이었다. 면역 활성을 높여주고 혈압강하 활성이 높다고 알려진 GABA함량이 50% 이상을 점하고 있어 매우 유용한 기능성 식품 소재로 판단된다. 지방산 조성은 linoleic, palmitic acid, oleic acid, linolenic acid 순으로서 품종 간에 큰 차이가 없었고 불포화 지방산의 비율이 67.2-76.0%로서 매우 높았다. 무기질 함량은 K이 0.354-0.492% 으로서 가장 높았으며 Mg 0.0516-0.0546 %, Ca 0.045-0.0486 %, Na 0.0101-0.0204 % 이었다. 항산화 물질로 알려진 포황 중의 flavonoid는 quercetin이 0.169-0.186 %로서 대부분을 차지하였고 rutin이 0.0094-0.0147 %이었다. SD계 rats에 4주간 포황과 그 추출물을 식이하면서 rats의 혈청에서 DPPH radical 소거활성을 알아 본 결과 소거활성 효과가 유의하게 나타났고, 혈중 cholesterol 함량을 낮추어 주는 효과와 혈중 glucose 함량을 낮추어 주는 결과로 보아 고지혈증의 예방과 당뇨병 치료에 효과가 있을 것으로 판단되었다.

For utilizing Cattail pollen as a raw material for functional foods, the nutrients such as free sugar, free amino acid, fatty acid composition, flavonoid content, and the biological activity within Cattail pollen were measured. The results of proximate analysis within Cattail pollen included the following readings: 12.7-13.2% of moisture, 15.7-17.8% of crude protein, 1.3% of crude fat, 7.5-7.7% of free sugar, 13.7-18.6% of crude fiber, 3.4-4.9% of ash, and 49.7-55.9% of nitrogen free extracts. The composition of free amino acids consisted of 1.923% of T. orientalis, 0.907% of T. angustata, and 0.333% of T. latifolia, which were measurements that varied significantly among different species. However, all species showed considerable portions of GABA alanine, glutamic acid, and proline. Specifically, it was shown that the GABA composition, which is known for increasing immunity while simultaneously lowering blood pressure, exceeded 50%. Therefore, this result implies that Cattail pollens have potential as a powerful utilization for functional foods. The composition of the fatty acids mainly consisted of linoeic, palmitic acid, oleic acid, and linolenic acid, and didn't show many variances across different species. Also, the total contents of unsaturated fatty acid were particularly high with a measured ratio of 67.2-76.0% value. Mineral in Cattail pollen was composed of 0.354-0.492% of K, 0.0516-0.0546% of Mg, 0.045-0.0486% of Ca, and 0.0101-0.0204% of Na. Among the Cattail pollens known as anti-oxidants, flavonoid contains 0.169-0.186% of quercetin, and therefore is the largest constituent followed by rutin making up a measurement of 0.0094-0.0147%. For the purpose of the study, the Cattail pollen and its extracts were fed to SC class rats for a span of 4 weeks. Then, the DPPH radical scavenging activity was measured from the tested rats'serums and the results showed significant variances. Also, the results indicated that the cholesterol and glucose levels in the blood were decreased which in turn led to the conclusion that the cattail pollen can help hyperlipidemia and diabetic treatments.
