Three sterol fractions; 4-desmethyl-, 4-monomethyl-, and 4,4-dimethylsterol, separated by thin layer chromatography from the unsaponifiables of five Cucurbitaceae (cucumber, watermelon, sponge cucumber, gourd and snake gourd) seed oils were analyzed by gas liquid chromatography and combined gas liquid chromatography-mass spectrometry. ${\alpha}$-Spinasterol, ${\Delta}^{7,22,25}$-stigmastatrienol and ${\Delta}^{7,25}$-stigmastadienol isolated from the 4-desmethylsterol fraction were identified by IR, NMR and mass spectrometry.

Five steroids $(campesterol,\;stigmasterol,\;{\beta}-sitosterol,\;{\alpha}-spinasterol\;and\;stigmast-7-enol)$ were isolated as mixture from $Siegesbeckia\;pubescens\;M_{AKINO}$ and analyzed by mass spectrometry.

A glucoside mixture of ${\alpha}$-spinasterol and ${\delta}^7$-stigmastenol was isoated from the roots of Phytolacca esculenta $_{VAN}$ H$_{OUTTE}4. This the first reported occurrence of these glucosides in Phytolaccaceae family.

Phytolaccagenin, as a minor free terpenoid, was isolated from the roots of phytolacca esculenta van Houtte. A mixture of sterols was also isolated and identified as ${\alpha}$-spinasterol and ${\delta}^7$-stigmastenol, which never seemed to have been found in phytolaccaceae.

From the roots of Codonopsis pilosula (Franch.) Nannfeldt (Campanulaceae), ${\alpha}$-spinasterol, mp $165{\sim}7^{\circ}$ and alpha-spinasteryl D-glucoside, mp $283{\sim}5^{\circ}$, were isolated and identified on the basis of chemical and spectral data. Spectral data showed that $\Delta^7-stigmasterol$ and its glucoside were contained as minor components.

An acylated steryl glucoside preparation has been isolated from Phytolacca esculenta $_{VAN}H_{OUTTE}$. Two componentsof the vsterol moiety are ${\alpha}$-spinasterol and ${\delta}^7$-stigmastenol. Fatty acids are palmitic, stearic and myristic acids, and are located on C-6 of the glucose portion. 6'-Palmityl-${\alpha}$-spinasteryl-${\beta}$-glucoside is the main component.

The chromatographic separation of MeOH extract of the aerial parts of Aster glehni (Compositae) led to the isolation of three sesquiterpenes, two sterols and four terpenes. Their structures were determined to be $\beta$-amyrin acetate (1), phytol (2), alismol (3), $\alpha$-tocopheryl quinone (4), $\alpha$-spinasterol (5), 10-O-methyl alismoxide (6), alismoxide (7), and 3-O-(6'-O-palmitoyl-$\beta$-D-glucosyl)-spinasta 7,22-diene (8) by physicochemical and spectroscopic methods . These compounds (1-8) were first isolated from the Aster glehni.

From the herbs of this plant, six compounds were isolated and their structures were characterized as dieicosyl ether (1), scopoletin (2), ${\alpha}-spinasterol-3-O-{\beta}-D-glucopyranoside$ (3), kaempferol (4), quercetin (5), and quercetin 7, 3', 4'-trimethylether-3-O-rutinoside (6) by chemical and spectroscopic evidences. These compounds were isolated for the first time from this plant and compound 6 was first isolated from nature.

In the previous paper the isolation of .alpha.-spinasterol and its glucoside from ether fraction of Codonopsis pilosula was reported. In continuation of earlier work, further component was investigated and led to isolation three tirterpenoids. Repeated column chromatography on silica gel of the ether extract resulted in the isolation of taraxeryl acetate, mp $298~301^{\circ}$, friedelin, mp $263~265^{\circ}$, and taraxerol, mp $289~8^{\circ}$. All the compounds were identified on the basis of spectral data and chemical reactions.

The roots of Codonopsis lanceolata contained ${\alpha}$-spinasterol. ${\delta}^7$-stigmastenol, oleanolic acid, echinocystic acid, and an unidentified triterpene acid, mp $249{\circ}$.
