  • The stem barks, heartwoods, and leaves of Acer tegmentosum (Aceraceae) are widely used in Korea to treat hepatic or cerebral disorders mainly due to alcohol poisoning. This study was aimed to analyze phenolic substances in A. tegmentosum. Quantitative analysis of the three phenolic substances (salidroside, (+)-catechin and scopoletin) was performed by HPLC and the identification of volatile phenolic substances were done by GC-MS. The contents of the three compounds in the three MeOH extracts were higher in the stem bark (salidroside: 80.22 mg/g, (+)-catechin: 23.31 mg/g, and scopoletin: 9.45 mg/g) compared to the heartwoods and leaves. And GC-MS analysis of the stem bark extract demonstrated that p-tyrosol is a main substance of twenty-one compounds identified.

  • Sequences from the internal transcribed spacer (ITS) regions of nuclear ribosomal DNA were determined to assess their potential as a phylogenetic tool for Korean Acer species, including A. okamotoannum and A. takesimense which are endemic on Ullung Island of volcanic origin. Although the genus Acer has been studied by various authors, different infrageneric dispositions have been suggested, and the phylogeny of the genus has been in dispute. The variation of ITS sequences from seven species of Acer was very low among species within the same section, but comparative analysesof the molecular data obtained suggest that ITS sequences may provide enough phylogenetic resolution for sectional relationships in the genus.

  • Two phenolcarboxylic acids. five flavonoids and one hydrolysable tannin were isolated from the leaves of Acer ginnala Maxim. On the basis of chemical and spectroscopic evidence, the strutures of these compounds were established as gallic acid, ethylgallate, acertannin, quercetin, quercitrin, isoquercitrin, rutin, $quercetin-3-O-{\alpha}-_L-rhamnopyranosyl-2'-gallate$.

  • In our present investigations, distributions of Korean Aceraceae with single genus composed of 16 species, 14 varieties and 1 form were studied. Distributional atlases were made by UTM grid map and drawing methods have been previously described (Distribution Atlas of Plants of Korea I, II, and III). Acer okamotoanum and A. takesimense of Korean endemic species are commonly distributed in Dagelet Island but the latter also in such islands as Quelpart, Wan-Do and Heucksan-Do. A. palmatum var. nakaii is found in the middle and the northern parts of the subtropics, and A. micro-sieboldianum and A. nudricarpum restricted to the middle part of the country are endemic species of Korea. A. barbinerve and A. tegmentosum as species from the north are distributed to the top of Mt. Chiri in the south and are also found in Mt. Nangrim and Baiktu in the north. A. ginnala and A. mono are commonly distributed in Liaotung-Pantao and Shantung-Pantao, or Chinese peninsulas, and South Manchuria with Korean Peninsula. A. barbinerve, A. tegmentosum, A. triflorum, A. tschonoskii and A. ukurunduense in south Manchuria, north Manchuria and Korea are florae derived from Manchuria, and A. japonicum, A. momo var. ambiguum, A. mono var. savatieri, A. palmatum var. matsumurae and A. ukurunduense var. pilosum appear in Korea and Japan.

  • Two triterpenoid saponine were isolated from the stems of Acer ginnala Maxim. The structures of triterpenoid saponins were established as ilexoside O, $3-O-{\alpha}-L- rhamnopyranosyl(1{\rightarrow}2)-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-xylopyranosyl-pubescenolic$ acid 28-{\beta}-D-glucopyranosyl$ ester(1) and ilexoside K, $3-O-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-xylopyranosyl-pubes-cenolic$ acid $28-{\beta}-D-glucopyranosyl$ ester(2). Their chemical structures have been elucidated on the basis of spectral methods.

  • The chemical constituents of Acer komarovii Pojark. which belongs to Aceraceae has never been reported. The bark of A. komarovii was extracted with 70% aqueous acetone, and the concentrated extract was successively partitioned with n-hexane, dichloromethane, ethyl acetate and $H_2O$. From the ethyl acetate soluble fraction, four compounds were isolated by the repeated Sephadex LH-20 and RP C-18 column chromatography. From the results of spectroscopic methods including FAB-MS, 1D and 2D NMR, the structures of the compounds were determined as quercetin (1), guaijaverin (2), hirsutrin (3) and hyperin (4). These compounds (1-4) have not been reported in this tree yet.

  • In the course of screening anti-adipogenic activity of natural products employing the preadipocyte cell line, 3T3-L1 as an in vitro assay system, the EtOAc fraction of the stem barks of Acer tegmentosum Maxim (Aceraceae) showed significant inhibitory activity on adipocyte differentiation as assessed by measuring fat accumulation using Oil Red O staining. Activity-guided fractionation led to the isolation of active constituent, (+)-catechin. (+)-Catechin showed inhibitory activity on adipocyte differentiation in dose-dependent manner. Further studies with interval treatment demonstrated that (+)-catechin exerted inhibitory activity on adipocyte differentiation via acting on early stage of adipogenesis. Our present study also showed that (+)-catechin significantly inhibited the preadipocyte proliferation. Taken together, these results suggest that (+)-catechin, a constituent of A. tegmentosum might contribute the anti-adipogenic activity of A. tegmentosum.

  • Taxa of the herbivorus insect larvae and their foodplant species were surveyed in a temperate forest of Namhansansung Area, Sungnam City, Kyonggi Province, in 1994-1996 growing season, Sixty two taxa of insect larvae fed on leaves of 18 woody species in 11 families during three growing season. Larvae began to be detected from the mid-April when the leafing time began. The number of larvae taxa reached to the maximum value(32 taxa) early in May, 1994. It was the time that the value of specific leaf area reached to the maximum. It decreased up to 3-4 taxa in the mid-June. Taxa of insect larvae were different year by year even in the same season. Most of larvae fed on various plant species, suggesting that they were generalist or polyphagous species. Fagaceae, Betulaceae, Ulmaceae, Rosaceae. Aceraceae, Ericaceae, Oleaceae and Styracaceae were fed on by many taxa of insect larvae, while Euonymus spp. (Celastraceae). Lindera obtusiloba(Lauraceae) and Symplocos chinensis for. pilosa(Symplocaceae) were mainly fed on by a few taxon.. Erannis, Calospilos and Phigalia were observed to feed on various species, but Illiberis, Pryeria and Chalocosia fed on only Rosaceae, Euonymus spp.(Cerastraceae) and Symplocos chinensis for. pilosa(Symplocaceae), respectively. An unidentified larva was observed only on Lindera obtusiloba (Lauraceae).
