3alpha, 7alpha-Dihydroxy-5beta-cholan-24-oic acid in acetic acid was treated with concentrated hydrochloric acid at room temperature. Two of the dehydration products thus obtained proved to correspond to the beta- and gamma-acids reported (5). One (gamma-acid) of these was identified as 3alpha-hydroxy-5beta, 14beta-chol-8-en-24-oic acid (IIa) by means of several spectral measurements of itself and its OsO4 oxidation products. Chemical structure of the other (beta-acid) remains undetermined.
在室温下，将3α, 7α - 二羟基 - 5β - 胆烷 - 24 - 酸在乙酸中用浓盐酸处理。由此得到的两种脱水产物被证明与已报道的β - 酸和γ - 酸相对应(5)。其中一种(γ - 酸)通过对其自身及其OsO₄氧化产物的几次光谱测量，被鉴定为3α - 羟基 - 5β, 14β - 胆 - 8 - 烯 - 24 - 酸(IIa)。另一种(β - 酸)的化学结构尚未确定。
