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.

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.

Aruncus aethusifolius (H. Lév.) Nakai is an endemic species in Korea and is economically important as an ornamental herb. The complete chloroplast genome of A. aethusifolius is 157,217 bp long with four subregions consisting of 85,207 bp of large singlecopy and 19,222 bp of small single-copy regions separated by 26,394 bp of inverted repeat regions. The genome includes 131 genes (86 protein-coding genes, eight rRNAs, and 37 tRNAs). Phylogenetic analyses demonstrates that the chloroplast genome of A. aethusifolius was sister to A. dioicus var. kamtschaticus, forming the strongly supported clade of Aruncus. This is the first report of the chloroplast genome of A. aethusifolius.

A new quercetin 3-O-trisaccharide was isolated from the leaves of Rubus crataegifolius (Rosaceae). The structure of this compound was determined as quercetin $3-O-{\alpha}-L-arabinofuranosyl-(1{\rightarrow}2)-{\beta}-D-xylopyranosyl-(1{\rightarrow}2)-{\beta}-D-galactopyranoside$ on the basis of 2D-NMR spectroscopic data. This flavonol glycoside was isolated for the first time from a natural source.

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.

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.

The chromatographic separation of a methanol extract of Prunus mume (Rosaceae) led to the isolation of 5-hydroxymethyl-2-furaldehyde (1), 4-O-caffeoylquinic acid methyl ester (2), prunasin (3), 5-O-caffeoylquinic acid methyl ester (4), benzyl-O-${\beta}$-D-glucopyranoside (5), and liquiritigenin-7-O-${\beta}$-D-glucopyranoside (6). Their structures were determined by 1D, 2D-NMR and MS data analysis as well as by comparison of their data with the published values.

Rubus nishimuranus Koidz. (Rosaceae), a species previously unrecorded for the Korean flora, was collected in the lowlands near a beach on Jeju Island. This species was known to be distributed only in Japan. R. nishimuranus differs from R. trifidus Thunb. ex Murray, by having leaves 3-foliate or sometimes the upper leaflets connate below and from R. hirustus Thunb. by having leaves ternate and the leaflets sessile or nearly so. The somatic chromosome number was 2n = 2x = 14 and the size of chromosomes ranged $1.2-2.5{\mu}m$. The chromosome complement of this species consisted of three pairs of metacentrics (chromosomes 1, 2 and 5), submetacentrics (chromosomes 3, 6 and 7) and a pair of subtelocentrics (chromosome 4).
