  • Phytochemical investigation of the aerial parts of Lonicera etrusca resulted in the isolation of three iridoids including two aglycones, loganin aglycone (log-1) (1) and lonicerin (log-2) (2), and the known common glycoside loganin (4). The study also afforded a coumarin derivative, 7-hydroxycoumarin (3), and a flavonoid glycoside, luteolin-7-O-$\beta$-D-glucoside (5). The structures were determined utilizing physical, chemical and spectral methods.

  • An insecticidal isoflavon glycoside was isolated from the roots of Maakia ammurensis. Its structure was shown to be formononetin-7-O-$\beta$ glucosy [1-6] glucoside [1] by chemical and spectroscpic methods and to have insecticidal activities against Brown planthopper female adults by spray and topical applications.

  • A new flavonol glycoside, quercetin 3-rhamnosyl $(1{\rightarrow}3)$ galactoside [5] was isolated from the leaves of M. africana. The known compounds kaempferol 3-rutinoside [1], 3'-O-methylquercetin 3-rutinoside [2], quercetin 3-rutinoside [3], and quercetin 3-rhamnosyl $(1{\rightarrow}6)$ galactoside [4] were also isolated for the first time from this plant. Their structures were determined by chemical and spectroscopic methods.

  • From the leaves of Lindera sericea Bl., kaempferol-3,7-0-di-a-L-rhamnopyranoside was isolated and characterized by spectral data and acid hydrolysis. This compound is reported for the first time from this plant. The content of kaempferol glycoside was high in May and June, and low in the fall. And the methoanolic extract of title plant showed the inhibitory effect on carrageenin-induced edema.

  • The constituents of Ranunculaceae plants are summerized from more than one hundred of papers. Fifteen steroidal alkaloids, thirty two of terpenoids (diterpenes and triterpenes), fifty four isoquinoline alkaloids are recorded. Thirty three papaverines, eighteen berberines, and three hydrastines belong to isoquinoline group. Besides, of alkaloids a number of glycosides are also found. Adonis glycoside, famous cardiotonics, from Adonis and cyanogenin glycoside and calthoside D were identified from the leaves of Thalictrum aquilegifolium and Caltha silvestris. Anemonin, the irritating substance, found in Pulsatilla grandiz $W_{ENDER}$. Kaempf-erol and dihydrokaempferol were isolated and identified from the leaves of Clematis brachyura ^M_{AXIMOWICZ}$ by author in 1968.
