A sterol mixture, 3-O-glucosides of these sterols, 6'-O-fattyacyl ester of these sterol glucosides, kaempferol, quercetin and isoquercitrin were isolated from the whole plants of Hypericum ascyron L. The sterols were found to be a mixture of ${\beta}-sitosterol$, campesterol and stigmasterol by GC-MS. The kinds of fatty acids linked at 6'-OH of sterol glucoside ester mixture were shown to be palmitic acid, stearic acid, oleic acid and linoleic acid by GC-MS. Three flavonoids were identified by spectroscopic methods and comparisons of mixed mp and co-TLC with authentic specimens.

The contents of sterols in bean sprouts have been determined by mass spectrical analysis. From non-saponifiable fraction of n-Hexane extracts of the under ground parts sterol-like substance $(m.P.\;142-145^{\circ}C)$ was isolated. It was shown to be a sterol mixture on the basis of three peaks in gas liquid chromatogram. By mass spectrometrical analysis of the mixture, it was composed of 4.52mg% of Campesterol $(C_{28},\;{\Delta}^{5})$, 10.35mg% of ${\beta}-sitosterol\;(C_{29},\;{\Delta}^{5})$ and 7.75mg% of stigmasterol $(C_{29},\;{\Delta}^{5,\;22})$.

The carpophores of Phallus impudicus collected at Gal-mae-ri in Gyeong-gi Province were subjected to chemical analysis for sterol constituents. The dried carpophores were homogenized and extracted with chloroform-methanol(2 : 1). After saponification of the dried extract, unsaponified components were obtained by ether extraction of the reaction mixture. A sterol fraction was separated by preparative TLC and from this fraction, ergosterol was identified by gas­chromatographic analysis with authentic sterols.

A mixture of sterols containing ${\beta}-sitosterol$ and stigmasterol (1), and sterol glycosides containing $3-O-{\beta}-D-glucopyranosyl$ ${\beta}-sitosterol$ and $3-O-{\beta}-D-glucopyranosyl$ stigmasterol (2) were isolated from the leaves of Gynura procumbens. After acetylation of 2 with pyridine-acetic anhydride, $3-0-{\beta}-D-tetra-O-acetylglucopyranosyl$ ${\beta}>-sitosterol$ (3) was isolated.

From the legumes of Albizzia julibrissin Durazzini (Leguminosae), a mixture of long-chain alcohols, ${\alpha}-spinasterol$, a mixture of acylated sterol glycosides and ${\alpha}-spinasteryl$ $3-O-{\beta}-D-glucoside$ were isolated. Two mixtures of long-chain alcohols and acylated sterol glycosides were characterized as 1-hexacosanol (major) and 1-tetracosanol, and $3-O-[6'-O-palmitoyl-{\beta}-D-glucosyl]-{\alpha}-spinasterol$ (major) and its 6'-O-stearoyl ester. All compounds were identified on the basis of spectral data and chemical reactions.

From the dried roots of Caragana chamlagu Lamarck which have been known to be effective against neuralgia, arthritis, migraine, and sputum, etc. in the folk medicines of Korea, a colorless sterol-like substance, C$_{29}H_{50}O$, m.p. $115-117^{\circ}$, was isolated from the non-saponified fraction of methanolic extract. It was confirmed to be a mixture of four sterols, namely cholesterol, brassicasterol, campesterol, and $\beta$-sitosterol by physico-chemical properties, ir, nmr, mass spectra and gas liquid chromatographic method with the comparison of the authentic samples. In mass fragments of four sterols, furthermore, the same ions of m/e 273, 255, 229 and 213 were assigned to fragments of stigmastane skeletons of the unsaturated phytosterol, and the characteristic ions of each sterol were observed 386, 371, 368, 353 in cholesterol, 398, 383, 380, 365, 355, 337 in brassicasterol, 400, 385, 382, 367 in campesterol and 414, 399, 396, 381 in $\beta$-sitosterol, respectively.

Pericarp of Zanthoxylum coreanum Nakai have been used as a crude medicine for the treatment of ozena, rheumatoid, nasal sinusitis, meno-xenia, dyspepsia, toothache, sore throat, pains in the limbs, etc. in Korea. A sterol fraction and two compounds, compound I and II were isolated from the roots, stems, leaves of Zanthoxylum coreanum Nakai. The sterol fraction was identified as a mixture of ${\beta}-sitosterol$ and campesterol. Compound I, colorless prismatic crystals, $C_{13]H_{13}NO_4$, mp. $175{\sim}177^{\circ}$, was proved to be skimmianine which is one of the alkaloids and compound II, $C_{14}H_{28}O_2$, mp. $53{\sim}55^{\circ}$, white powdered crystals was identified as myristic acid.
