The activity-guided fractionation upon the MeOH extract of the aerial parts of Sorbaria sorbifolia var. stellipila led to the isolation of two cucurbitacin-compounds, cucurbitacin D and cucurbitacin F, as active principles. Two compounds were shown to exhibit significant cytotoxicity against cultured human tumor cell lines, A-549, SK-OV-3, SK-MEL-2, XF-498, and HCT 15.

The purpose of this study was to evaluated the antioxidative constituents and their activities of the 80% methanolic extracts from fruit of Sorbaria sorbifolia var. stellipila MAX. The isolation of active compound was performed in three steps: solvent partition, open column chromatography, and high-performance liquid chromatography (HPLC). The solvent fractions were tested for their antioxidant activities by oxygen radical absorbance capacity (ORAC). The antioxidant activity of 80% methanolic extracts by various solvent partitions was in the order of 80% MeOH (1.68 ${\pm}$ 0.027), n-hexane (1.02 ${\pm}$ 0.036), $CH_2Cl_2$ (0.95 ${\pm}$ 0.025), EtOAc (1.98 ${\pm}$ 0.065), n-BuOH (1.94 ${\pm}$ 0.054) and Water (1.28 ${\pm}$ 0.032). Therefore, the results indicated that the potential antioxidant activities and functional values were observed significantly at EtOAc fraction from fruit of S. sorbifolia, flavonoid compound isolated.

We report an unrecorded species of the genus Sorbaria (Rosaceae) in Korea, namely Sorbaria kirilowii (Regel & Tiling) Maxim. This plant was discovered both on Pocheon-si, Naecheon-myeon and Yeoju-gun, Buknae-myeon in Gyeonggi Province. It is distinguishable from Sorbaria sorbifolia (L.) A. Braun var. stellipila Maxim. by characteristics such as presence of hair on leaf and rachis, morphology of inflorescence, length and width of petal, shape of sepal, number and length of stamens, presence of hair upon and size of follicles. This taxon was given the Korean common name 'Jom-swi-ttang-na-mu' based on the small size of floral characters.

The antioxidant activities and total phenolics of four Rosaceae species Pourthiaea villosa (Thunb.) Decne, Sorbus commixta Hedlund, Sorbaria sorbifolia var. stellipila Maxim and Pyrus pyrifolia (Burm.f.) Nakai were determined. Phenolic content (polyphenol and flavonoid), radical scavenging activities [2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis (3-ethylnezthiazoline-6-sulfoic acid) (ABTS)] and ferrous ion chelating effect were evaluated. Total polyphenol and flavonoid contents were highest in Pourthiaea villosa (Thunb.) Decne and lowest in Pyrus pyrifolia (Burm.f.) Nakai. Phenolic contents of Pourthiaea villosa (Thunb.) Decne was $331.45{\pm}7.78$ and $90.4{\pm}3.5mg{\cdot}g^{-1}$. DPPH and ABTS radical scavenging activities were found to be lowest in Sorbus commixta Hedlund whereas Sorbaria sorbifolia var. stellipila Maxim and Pourthiaea villosa (Thunb.) Decne showed relatively good DPPH and ABTS radical scavenging activities. Ferrous ion chelating effect was highest in Pyrus pyrifolia (Burm.f.) Nakai ($1.05{\pm}0.04mg{\cdot}ml^{-1}$) and lowest in Sorbus commixta Hundlund ($4.22{\pm}0.71mg{\cdot}ml^{-1}$).

In the present study, the anti-oxidative properties of 80% ethanol extracts from 140 kinds of natural plants were investigated. Persicaria perfoliata had the highest anti-oxidative relative potency(VitaminE, $ORAC_{PE}$=1.0), followed by Sorbaria sorbifolia var. stellipila, Rosa multiflora, Lysimachia vulgaris var. davurica, Quercus aliena, Quercus mongolica and Lespedeza bicolor ($ORAC_{PE}$ ${\geq}$ 1.50). Among them, the anti-oxidative activity values of the n-hexane, $CH_2Cl_2$, EtOAc, n-BuOH, and water fractions of the 80% EtOH extracts of P. perfoliata and S. sorbifolia in the ORAC assay system were $1.13{\pm}0.002$, $1.10{\pm}0.004$, $3.67{\pm}0.232$, $1.62{\pm}0.049$ and $1.05{\pm}0.003$; $1.02{\pm}0.007$, $1.00{\pm}0.016$, $2.94{\pm}0.130$, $1.80{\pm}0.019$ and $1.04{\pm}0.012$, respectively, with marked anti-oxidative activity in the ethyl acetate fraction from selected the 2 plant extracts.

In this study, we analyzed 80%MeOH extract of fruits of sorbaria sorbifolia var. stellipila MAX. to measure the total antioxidant capacity by oxygen radical absorbance capacity (ORAC) assay, individual flavonoid content by high-performance liquid chromatography (HPLC). n-Hexane ($1.02{\pm}0.036$), $CH_2Cl_2$ ($0.95{\pm}0.025$), EtOAc ($1.94{\pm}0.065$), n-BuOH ($1.98{\pm}0.054$), D.W. ($1.2{\pm}0.032$) fractions were examined antioxidative activity by ORAC assay. It was revealed that EtOAc($1.94{\pm}0.065$), n-BuOH($1.98{\pm}0.054$) fractions had significant antioxidative activity. The isolation and separation were facilitated using open column chromatography, while separation, purification and identification were accomplished by using high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR).
