한국산 부자류 생약에 관한 연구 (Ⅲ). : 그늘돌쩌귀(Aconitum uchiyamai)의 diterpene alkaloid에 대하여
정보섭(Bo Sup Chung),이형규(Hyeong Kyu Lee),이현선(Hyun Sun Lee) 한국생약학회 1988 생약학회지 Vol.19 No.3
A diterpene alkaloid and a disaccharide were isolated from the root of Aconitum uchiyamai, and identified as mesaconitine and sucrose respectively by UV, IR, MS, and NMR data
자란초의 Iridoid glucoside에 대한 연구(1)
정보섭(Bo Sup Chung),이형규(Hyeong Kyu Lee),김진웅(Jin Woong Kim) 한국생약학회 1980 생약학회지 Vol.11 No.1
From the whole plant of Ajuga spectabilis Nakai (Labiatae) a iridoid glucoside was isolated. Its structure was assigned mainly on the PMR-data for the glucoside itself and its acetate. Proton coupling constantand and chemical shift are utilized for estimating the most favoured conformations of the compound. This compound was found that molecular formular was C_(17)H_(26)O_(12) and that acetylation gave heptaacetate derivative.
한국산 수유나무의 Triglyceride 조성에 관한 연구 (Ⅲ)
정보섭(Bo Sup Chung),고영수(Young Su Ko) 한국생약학회 1979 생약학회지 Vol.10 No.1
The Korean Euodia daniellii HEMSLEY seed oil of triglyceride composition were analysed by thinchrography. Responses of sterol, triglyceride, sterol ester and acetate on a thin layer chromatographic apparatus, which was equipped with a flame ionization detector were determined. It was found that thinchrography is very superior and convenient means for the estimation of seed oil triglyceride compositions. The triglyceride compositions were tripalmitin 7.3%, tristearin 1.8%, triolein 21.1%, trilinolein 32.9%, trilinolenin 33.4% and unknown 3.5% in the case of Euodia daniellii seed oil in Korea.
Iridoid Glycoside (Ⅰ) : Studies on the Iridodid Glycoside of Ajuga spectabilis Nakai
정보섭(Bo-Sup Chung),이형규(Hyung-Kyu Lee),김진웅(Jin-Woong Kim) 한국생약학회 1980 생약학회지 Vol.11 No.1
A new iridoid glucoside was isolated from the whole plant of Ajuga spectabilis Nakai (Jaran-cho; Labiatae). This compound was obtained as white plate-like crystal and named as Jaranidoside. It has a molecular formula C_(17)H_(26)O_(12) and mp 128∼130℃. The structure of the Jaranidoside was assumed from data of chemical reactions and PMR specturum of the compound. To determine the most favorable conformation, informations on the proton coupling and chemical shift were used. Jaranidoside exhibited a stimulating activity on smooth muscle and cardiac muscle. No antimicrobial activity on five microorganism strains was observed.
한국산 부자류 생약에 대한 연구 (Ⅰ) : 노랑투구꽃의 성분 연구 및 관련된 부자류의 독성 비교
정보섭(Bo Sup Chung),김신근(Sin Keun Kim),이형규(Hyung Kyu Lee),김승한(Seung Han Kim) 한국생약학회 1984 생약학회지 Vol.15 No.2
The structure of tuguaconitine, mp 196∼198℃, a new diterpene alkaloid isolated from the roots of Aconitum sibiricum P., was studied. Its empirical formula is C_(23)H_(35)NO<sub>7</sub> and spectroscopic evidence shows that the base contains three methoxyl, three hydroxyl and one N-ethyl groups. The acute toxicities of most of Aconitum species were strong and the acute toxicity of the alkaloid fraction of A. sibiricum was decreased by Glrcyrrhizae, black bean or Zingiberis extract.

Assarinin and N-isobutyl-2E, 4E, 9Z, 10E-do-decatetraenamide were isolated from the root of Asarum maculatum (Aristolochiaceae, Korean Asarum species) and their structures were elucidated on the basis of spectral data.
이리도이드 배당체(Ⅵ) : 조개나물의 이리도이드 배당체
정보섭(Bo Sup Chung),유완근(Woan Keun Yoo) 한국생약학회 1985 생약학회지 Vol.16 No.3
Ajuga multiflora Bunge is a perennial herb in the family of Labiatae. The iridoid glycoside was isolated from the ethylacetate fraction and the n-butanol fraction of the plant. The structure of the substance was identified as 8-O-acetylharpagide by UV, IR, NMR spectra and several chemical reactions.
정보섭(Bo Sup Chung),김하균(Ha Gyun Kim) 한국생약학회 1985 생약학회지 Vol.16 No.3
Isomotiol (fern-8-en-3β-o1) was isolated from the n-hexane fraction of Euphorbia supina Rafin. The structure of isomotiol was identified by IR, NMR, Mass spectra and compared with the authentic sample. Isomotiol was first isolated from the family of Euphorbiaceae.
한국산 인삼의 성분에 관한 연구(Ⅰ) : 인삼 Sterol의 구성 성분에 대하여
정보섭(Bo Sup Chung) 한국생약학회 1974 생약학회지 Vol.5 No.3
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 β-sitosterol were the major sterols in the ginseng. The results showed that contents of sterols were campesterol, 4.01∼5.82%, stigmasterol, 18.32∼19.12% and β-sitosterol, 75.11∼77.74%.

Two C<sub>19</sub>-diterpene alkaloids were isolated from the root of Aconitum pseudolaeve var. erectum Nakai, and indentified as lycoctonine and septentriodine by UV, IR, MS and NMR data.
