The cell components of an iron-oxidizing F.ferrooxidans were analyzed with heterotrophic E.coli as a control group. The large amounts of total carbohydrate and lipids were represented in F.ferrooxidans and especially the total lipids including total sterol, glyceride, and phospholipid possessed about 4.6% of total dry cell. In amino acids analysis, an unknown metrial was detected in F.ferrooxidans nad it is assumed that material is a ninhydrin-positive and have an association with lipid.

Spiraea prunifolia Sieb. et. Zucc. var. simpliciflora Nakai (Rosaceae) is distributed in Korea, and used as a folk medicine for antipyretic, antimalarial and emetic. Sterols were obtained from the methanolic extract of the root of above plant. The composition of sterols are campesterol and ${\beta}-sitosterol$ which has been determined by gaschromatographic analysis.

Sterols were obtained from the non-saponifiable matters of ethereal and methanolic extracts of the root of Panax ginseng. The composition of sterols has been determined by gas chromatographic analysis. It was noted that campesterol, stigmastrol and ${\beta}-sitosterol$ were the major sterols in the ginseng. The results showed that contents of sterols were campesterol, $4.01{\sim}5.82%,\;stigmasterol,\;18.32{\sim}19.12%\;{\beta}-sitosterol,\;and\;75.11{\sim}77.74%$.

From the roots of Pandia siamensis, D-mannitol, a mixture of .betha.-sitosterol and campesterol, oleanolic acid acetate, oleanolic acid-3-.alpha.-L-arabino side and mesembryanthemoidigenic acid as a sapogenin were isolated and characterized.

Sal, typhi, Ty 2 菌體에 電離放射線을 照射하여 放射線 照射時 隋半되는 菌體의 化學的 性狀을 比較 分析하였다. 放射線 2.5 Mrad, 5.0 Mrad 照射로서 酸性 Amino acid는 增加하였으나 中性 및 鹽基性 Amino acid는 若干 減少하였다. 5.0 Mrad 照射로서 菌體의 總 Carbohydrate 量은 49.7%, 總 Nitrogen 量은 44.6%, Lipid 에 있어서는 Sterol 40%, Glyceride 30%, Phospholipid 14%의 減少를 各各 나타내었다. Polyacrylamide gel 電基泳動結果 放射線 照射群에서는 對照群에 比하여 Cell membrane protein의 變性을 認知할 수 있었다.
