Studies on Inorganic Chinese Drugs in Korea (IV)

As a part of series of "Studies on Inorganic Chinese Drugs in Korea," four arsenic mineral Chinese drugs were analyzed by emission spectrographic method, and also were studied crystallographically by X-ray diffraction method. The following results were revealed: 1)Tang-shin-suk was not a Native arsenic but a Arsenolite which containing 94% of AS2O3, 2)Toh-shin-suk was Crade Aluminum silicate 3)Woong-whang was a Realgar AS2S2, 4)Yek-suk was a Ca-Al-Silicate which was mixed with alpha-quartz contaminated by Iron compound and trace amount of Arsenic. It was not verified that the presence of Arsenopyrite FeAsS which has been believed as a main component of Yeh-suk by a Japanese author Wakimizu, nor the presence of Arsenolite which was reported by Masutomi.
