A triterpene glycoside was first isolated from berries of Rubus coreanus Miquel in the family of Rosaceae, which have been used as a tonic in chinese drug. The compound was identified as $28-{\beta}-D-glycopyranosyl$ ester of $2{\alpha},3{\beta},19{\alpha},23-tetrahydroxyurs-12-en-28-oic$ acid by IR, MS, $^{1}H-NMR$, $^{13}C-NMR$ spectra.

Three compounds (1-3) were isolated from the roots of Potentilla discolor (Rosaceae). The structure of compounds 1-3 were elucidated as stigmast-5-en-3-ol $({\beta}-sitosterol,\;1),\;2,19{\alpha}-dihydroxy$-2-oxo-urs-1,12-dien-28-oic acid (fupenjic acid, 2), 3-O-${\beta}$-D-glucopyranosylstigmast-5-en-3-ol (${\beta}-sitosterol\;{\beta}-D-glucopyranoside, 3) based on physical and spectroscopic data. $^{13}C-NMR$ assignments were completed by 2D-NMR technique. The three compounds were firstly isolated from Potentilla discolor.

Phytochemical investigation of the aqueous extract of ~he roots of Agrimania pilosa Ledeb. (Rosaceae), as guided by hepatoprotective activity in vitro, furnished two isocoumarins, agri-monolide (1) and agrimonolide 6-O-$\beta$-D-glucoside (3), and (＋)-catechin (2). Compound 1 showed hepatoprotective effects on both tacrine-induced cytotoxicity in human liver-derived Hep G2 cells and tert-butyl hydroperoxide-induced cytotoxicity in rat primary hepatocytes with EC$_{50}$ values of 88.2$\pm$2.8 and 37.7$\pm$1.6 $\mu$M, respectively.y.

The chromatographic separation of n-BuOH extract of the aerial parts of Prunus padus (Rosaceae) led to the isolation of two cerebrosides, and six phenolic compounds. Their structure were identified to be pinelloside (1), soyacebroside I (2), $quercetin-3-O-{\beta}-D-galactopyranoside$ (3), nudiposide (4), (+)-isolarisiresinol $9'-O-{\beta}-D-xylopyroanoside$ (5), khaephuoside A (6) and icariside F2(7) by physicochemical and spectroscopic methods. The compounds $1,5{\sim}7$ are first isolated from the genus Prunus.

Antidepressant miquelianin (quercetin 3-O-glucuronide) was isolated from the leaves of Rubus craetaegifolius (Rosaceae) and identified by physical and spectroscopic data. Miquelianin was quantitatively analyzed in the leaves, mature and premature fruits of Korean wild R. craetagifolius, R. pungens var. oldhami, R. coreanus, and R. parvifolius by HPLC. The contents of miquelianin was highest in the mature fruit of R. crataegifolius ($16.29{\pm}0.79mg/g$); however, the content of kaempferol 3-O-glucuronide was $33.88{\pm}7.68mg/g$. These results suggest that the mature fruit of R. crataegifolius would be beneficial for treating depression or stress as a functional food with its sweet taste.

The studies were camied out to evaluate the constituents in the leaves of Crataegus pinnatifida var. psilosa (Rosaceae) continuously. From the BuOH fraction of the MeOH extract, four flavonoid compounds, hyperoside (1), vitexin (2), 3"-O-rhamnosylvitexin (3) and $quercetin-3-O-{\alpha}-L-rhamnopyranoslyl-(1{\rightarrow}6)-{\beta}$-D-galactopyranoside (4) were isolated and identified on the basis of their physico-chemical properties and spectroscopic evidences by comparison with authentic samples.

The MeOH extract of Sorbus commixta (Rosaceae) exhibited strong DPPH radical scavenging activity, and through activity-guided fractionation two antioxidant compounds were isolated and identified as $catechin-7-O-{\beta}-D-xylopyranoside$ (1) and $catechin-7-O-\;{\beta}-D-apiofuranoside$ (2) by physicochemical and spectrometric methods. To evaluate the antioxidant effect of these compounds, some in vitro tests, such as the DPPH radical scavenging activity test, the superoxide radical scavenging activity test and the lipid peroxidation inhibitory activity test, were performed. Compounds 1 and 2 showed stronger activities than both a-tocopherol and butylated hydroxy anisole (BHA) in each assay.

Korean folk medicine 'O-I-Pul' has been used to cure arthritis, neuralgia, leucorrhea, snake-bite, vomiting and diarrhea. With regard to the botanical origin of O-I-Pul, it has been considered to be Sanguisorba species of Rosaceae, but there has no pharmacognostical confirmation on it. Morphological and anatomical examination of Sanguisorba leaves show that 'O-I-Pul' was the leaves of S. Officinalis and S. tenuifolia var. alba.

Korean folk medicine 'JoPabNaMu' has been mainly used to cure removal of fever and neuralgia. With regard to the botanical origin of 'JoPabNaMu', it has been considered to designate the stem of Spiraea species (Rosaceae), but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'JoPabNaMu', the anatomical characteristics of the branch of Spiraea species growing wild in Korea were studied. As a result, 'JoPabNaMu' was proved to be the branch of Spiraea prunifolia var. simpliciflora.

Two lupane-type triterpenes, lupenone (1) and lupeol (2), a phytosterol, ${\beta}-sitosterol$ (3), two ursane-type triterpenes, $3{\beta}-acetoxy$ ursolic acid (4) and ursolic acid (5), a lignan, (-)-lyoniresinol $3a-O-{\beta}-D-xylopyranoside$ (6), and two flavanol glycosides, $catechin-7-O-{\beta}-D-xylopyranoside$ (7) and $catechin-7-O-{\beta}-D-apiofuranoside$ (8) were isolated from the stem bark of Sorbus commixta (Rosaceae). Their chemical structures were identified by physicochemical and spectroscopic methods.
