  • A comparative study of leaf anatomy in tribe Sorbarieae (Adenostoma, Chamaebatiaria, Sorbaria, Spiraeanthus) including one related genus Lyonothamnus was carried out using light microscopy. Anatomical characteristics of the leaf blade and midrib were described and taxonomically evaluated. The anatomical characters which described in this study are as follows: thickness of leaf midrib, blade in cross section, cuticle, epidermal cell, stoma, trichome, mesophyll, crystal, main vasculature type. All features were compared and the vascular patterns of midrib were distinguished two types. - Type 1: Trace tripartite (Adenostoma), Type 2: Trace continuous, subtype 2A: flat arc (Chamaebatiaria, Spiraeanthus), subtype 2B: U-shape arc (Lyonothamnus, Sorbaria). In conclusion, some of leaf anatomical characters (e.g., cuticle, epidermal cell, trichome, mesophyll, main vasculature type) can be useful for diagnostic features. Hypostomatic type, dorsiventral mesophyll, Ushape vasculature type would constitute a major characters for genus Sorbaria in Sorbarieae. The detailed anatomical description of studied taxa is provided, and its systematic importance is also briefly discussed.

  • 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.

  • We conducted principal component analyses using the quantitative characteristics of the genus Sorbaria to investigate and explore morphological variation and diagnostic characteristics. The genus Sorbaria was divided into two groups based on erect or pendulous inflorescence, the existence of hairs on the ovary and follicle surfaces, the number of stamens, and the shape of the sepal. As a result of our investigation and of a morphometric analysis, these two groups could be also classified using quantitative characteristics, in this case the number of leaflets, the size of the leaflets, the width of the inflorescence, the size of the sepal, the petal, and the follicles and seeds. In the Sorbifolia group (S. grandiflora and S. sorbifolia complex), the size of lateral leaflets, number of veins, gland and stellate density on the abaxial surface of leaflets, and the petal and follicle size were found to be useful identification characteristics. The terminal and lateral leaflet size and the gland and stellate density on the abaxial surface of the leaflets were found to be characters of taxonomic value for the Kirilowii group (S. arborea complex, S. kirilowii, and S. tomentosa complex). The results of the numerical analysis conducted here can provide valuable information to those reconsidering and delimiting a taxonomic revision of the genus Sorbaria.

  • A comparative petal micromorphology of 15 taxa of tribe Sorbarieae was carried out using scanning electron microscopy (SEM) in order to evaluate their taxonomic and systematic implication. The characteristics of both adaxial and abaxial side of petal epidermal cells such as shape, arrangement, anticlinal wall and cuticular sculpture were described in detail. The Sorbarieae petal epidermal cells were identified as papillate or conical papillate (PCS) and rectangular-rugose tabular (TRS). Three types of petal micromorphology were found within the tribe based on the cell patterns of adaxial and abaxial side. Type I. PCS-TRS, Type II. PCS-PCS, Type III. TRS-TRS (adaxial-abaxial side). The petal epidermal cell types, anticlinal cell wall, and cuticular sculpture represent not only taxonomical importance for identification between or within the genera but also systematic implication. Moreover, this study provides a relation between petal epidermal cell pattern and insect pollinator (entomophily; melittophily) as an additional case.

  • 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.

  • Cucurbitacin D and F, the protostane type triterpenoid of S. sorbifolia, were isolated with chromatograpic method and used as the standard substances for quantitative analysis. The compounds were identified with $^1H$-NMR, FAB-MS and UV spectrophotometer. They were separated on YMC-Pack ODS-AQ(303)[$250{\times}4.6mm$ I.D., $S-5{\mu}m$, 120A] column by HPLC. Cucurbitacin F was detected at 10.73mg/kg in cortex of S. sorbifolia, but cucurbitacin D was not. The compounds were shown to exihibit significant cytotoxicity($ED_{50}$<$0.1{\mu}g/mL$) against several tumor cell lines and acute toxicity(cucurbitacin D: 4.7mg/kg/day, cucurbitacin F: 2.5mg/kg/day) against BDF-1 mouse.

  • A comparative study of leaf epidermal microstructures in the tribe Sorbarieae (Adenostoma: 3 spp., Chamaebatiaria: 1 sp., Sorbaria: 11 spp., Spiraeanthus: 1 sp.) including related genera Gillenia (2 spp.) and Lyonothamnus (2 spp.) was carried out using scanning electron microscopy (SEM) in order to evaluate their significance in taxonomy. The leaves of Adenostoma, Chamaebatiaria, and Spiraeanthus were amphistomatic, whereas Gillenia, Lyonothamnus, and Sorbaria were hypostomatic. The size range of the guard cells is $7.84-48.7{\times}5.86-38.6{\mu}m$; the smallest one was found in Sorbaria tomentosa var. tomentosa ($7.84-11.8{\times}6.84-10.5{\mu}m$), while the largest measured example was Adenostoma fasciculatum var. obtusifolium ($30.3-48.7{\times}18.8-38.6{\mu}m$). Anomocytic stomata complex were the most frequent type (rarely cyclocytic), with usually both anomocytic and actinocytic types occurring in one leaf. On the surfaces, both the adaxial and abaxial anticlinal walls of the subsidiary cells vary (e.g., straight/curved, undulate, sinuate). Four types (unicellular non-glandular trichome, stellate, glandular trichome, pustular glandular trichome) of trichomes are found in the leaves. The epicuticular wax can be divided two types: membraneous platelets (Lyonothamnus) and platelets (Sorbaria arborea var. arborea, S. arborea var. subtomentosa, S. kirilowii, S. tomentosa var. tomentosa, Spiraeanthus schrenkianus). The trichome diversity (in particular, stellate, gland) and the existence of epicuticular wax may have taxonomic significance, although the leaf epidermal micromorphological characteristics do not provide synapomorphy in this tribe. These leaf micromorphological features are most likely better understood in the Sorbarieae when used in conjunction with external morphological characters.
