1-Isonicotnyl-2-furfurylidene Hydrazine-Cd(II) 착화합물에 관한 분석화학적연구
백남호(Nam Ho Pack),박만기(Man Ki Park) 대한약학회 1969 약학회지 Vol.13 No.1
A new organic reagent, 1-isonicotynyl-2-furfurylidene hydrazine synthesized from isonicotinic acid hydrazid and furfural, gives yellow liquid with cadmium (II). Cadmium complex of the reagent is soluble in water with yellow coloratiop. The complex has a maximum absorption at 363mmc and molar ratio of cadmium to reagent was estimated as 1 : 1 by continuous variation method and slope method. Molecular extinction coefficient and apparent formation constant of this complex was spectrophotometrically determined. K=4.48 X 103 (Babko''s method) K=1.33 X 103 (Anderson''s method)
녹용에 관한 연구(제 1 보) 녹용수침액의 유리아미노산에 대하여

Six kinds of free amino acids, leucine, methionine, threonine, lysine, histidine and aspartic acid were found by using partition paper chromatography from water extract of deer horn which is widely used as tonic drug. The results shows that deer horn does not contain any specific free amino acid.
