The content of luteolin in the different parts of Lithospermum erythrorhizon was determined by high performance liquid chromatography (HPLC). Luteolin was quantified by a reverse-phase column with gradient solvent program (water : ACN = 90 : 10 to 77 : 23 for 60 min). UV detection was conducted at 330 nm. The content of luteolin was measured in the seeds (0.28 mg/g), stems (0.30 mg/g), and roots (0.16 mg/g) of L. erythrorhizon. The presence of luteolin in Lithospermum species is important in agricultural crop production for increasing the amounts of clinically available medicine and health supplements.

The concentrations of HCHO(formaldehyde), PM10(particulate matter), CO₂(carbon dioxide) and TBC(total bacteria counter) distribution in schools(Chung-Nam Area) were examined, and the results were compared with the recommended criterion of the administration law of indoor air. The subjects were an elementary school, a middle school and a high school in Chung-Nam area, and the concentration of TBC was examined by Single Stage Air Cascade Sampler, which applied the inertia collision catching method of 28.29L/min(flux) during 5 months from March, 2007 to July, 2007. The instrument(LD-3B, SIBATA Company)was used to examine PM10, by a light scattering method and a light transmission method. The instrument(Airboxx(KD Engineering) was used to examine CO₂. The instument(Z300XP(Environmental sensor)was used to examine HCHO. The result indicated that the PM10 average concentrations of the surveyed classrooms were 49 μg/m3 in Spring and 59 μg/m3 in Summer. The CO₂ average concentration of the surveyed schools were 576 ppm in the classroom and 527 ppm in the stateroom. The average concentration of TBC were 729 CFU/m3 in an elementary school, 401 CFU/m3 in a middle school, 381 CFU/m3 in a high school. The HCHO average concentration of the surveyed schools were 0.03 ppm in the classroom, 0.02 ppm in the stateroom.

비타민 E를 구성하는 토코페롤(Tocopherol, T)과 토코트리에놀(Tocotrienol, T3)은 각각 alpha(a)-, beta(b)-, gamma(g)-, delta(a)- 의 이성질체가 존재하며 항산화, 항암 및 고지혈증 개선 등 효과가 뛰어난 물질로 알려져 있다. 국내에서 수집된 재래종 수도 유전자원을 대상으로 이들 성분의 함량 분포를 조사코자2 20개 품종을 선발하여 현미를 분석한 결과 평균적인 aT, bT, gT 및 총T 함량은 각각 8.3, 0.5, 1.2, 및 10.0 ug/g 이었으며, aT3, gT3, dT3 및 총 T3 함량의 평균치는 각각 6.7, 17.5, 0.7 및 24.7 ug/g이었다. 8종의 vit E 이성질체의 총 합으로 나타낸 총 vit E 함량의 최소, 평균 및 최대값은 각각 9.9, 60.3 및 34.6 ug/g 이었다. 변이계수를 기준으로 평가할 때, gT (CV=79%)의 함량 분포가 품종간 변이가 심한 것으로 나타났으며 aT 함량(CV=79%)은 가장 변이가 작은 것으로 나타났다. 분석된 220개 품종 중에서 가장 높은 aT, aT3, gT3 및 총 vit E 함량을 나타낸 품종은 각각 화성밭찰, 재래륙도, 조석조, 산도이었다.
