To develop an optimal storage method of root of Angelica acutiloba Radix, which has been grown as major herbal medicine material to be cultivated, root of Angelica acutiloba Radix, was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. In conclusion, vacuum packing and complete sealing with polyethylene film appears to be most optimal for storage of Angelica acutiloba Radix.

1. Ge는 명일엽(明日葉)이 일당귀에 비하여 2.1배 함유량이 더 높았다. 2. 분해 온도를 높이면 분해를 단시간에 할 수 있었으나 Ge 함량에 있어서는 낮은 온도로 분해할 때보다 낮았다 3. Ge 처리시 callus 형성은 일당귀가 명일엽(明日葉)보다 좋았으나 두 식물 모두 pH 5.7, 5.4, 6.0 순으로 좋았다. 명일엽(明日葉)에서는 일당귀와는 달리 pH 5.7에서 callus증식 중 신초형성이 많았다. 4. Callus형성에는 명일엽(明日葉)과 일당귀 모두 무기 Ge의 5 ppm까지 대체로 좋았으나 10 ppm부터 저해되다가 100 ppm에서는 거의 형성되지 않았고 유기Ge의 처리에서는 10 ppm까지 양호했고, 50 ppm부터 저해하지만 100 ppm에서도 다소 형성되었다.

The effects of various kind and amount of nitrogen fertilizers on the plant grorth. physiological , yield and extracts. ligustilide, butylidene phthalide contents of curdsdrug "Tou-ki" (AnTelica acutiloba Kitagawa) were investigated in 1989. Five plots variouskind of nitrogen fertilizers. Namely, no nitrogen, urea. ammonium nitrate, ammoniumchloride and control plot of ammonium sulfate. The other, by providing five plotsdifferent composed ratio of nitrogenous fertilizers. containing no nitrogen (No. o) .0.5-fold nitrogen (No s), control plot of 1.0-fold nitrogen(Nl.o). 1.5-fold nitrogen(Nl s)and 2.0-fold nitrogen Na. o), but nitogen was used the ammonium sulfate. The results showedthat the crude drug "Tou-ki" can ammonium chloride be produced in good yield, displayingboth good plant growth and remarkable physiologically-active conditions, and it can beproduced such that the extracts is maximized. Additionally, using methods of gaschromatography (GC) , it was established that ligustilide and butylidene phthalide, majorcomponents in the crude drug was recovered in a good yield from the fully grown plants.The other, the plant growth, the physiologically-active, the weight of whole plant, theyield of extracts and ligustilide, butylidene phthalide were seen to be best at the plotof 2.0-fold nitrogen and according to the increase or decrease of nitrogen decreasedgradually. Therefore. about 2 fold of standard quantity seems to be the most suitablequantity of nitrogen for "Tou-ki" cultivation .uot;Tou-ki" cultivation .ion .
