Nineteen compounds, including one organic acid (1), one anthraquinone (2), one amide (3), and sixteen triterpenoid saponins (4 - 19) were isolated from the leaves of Acanthopanax henryi (Oliv.) Harms (Araliaceae). Their structures were determined on the basis of physicochemical properties and spectral analyses (HR-MS and NMR). Among them, compounds 2, 3, 7, 12 and 19 were new within Araliaceae. Compounds 4, 5, 9 - 11, 13, 14, 16 and 18 were reported for the first time from the Acanthopanax genus. Except for compounds 4 and 9, other compounds were isolated from A. henryi (Oliv.) Harms for the first time. The rare anthraquinone, compound 2, significantly decreased the production of NO and the levels of other inflammatory factors, such as TNF-alpha and IL-6, in lipopolysaccharide (LPS)-stimulated macrophages in a dose-dependent manner. This is the first time to report anti-inflammatory effect of this compound.

Acanthopanax divaricatus, a member of the Araliaceae family, has been used as an invigorant in traditional Korean medicine. During disease monitoring, a stem with small, irregular, brown lesions was sampled at a farm in Cheonan in 2011. The symptoms seen were sunken cankers and reddish-brown needles on the infected twig. The isolated fungal colonies were whitish, having crenated edges and aerial mycelium on the surface, and with black gregarious fruiting bodies. The reverse plate was creamy white. Conidia were 17~22 x 3.5~4.2 microm, fusiform, 4-septate, and straight to slightly curved. The nucleotide sequence of the partial translation elongation factor 1 alpha gene of the fungal isolate, shares 99% sequence identity with that of known Pestalotiopsis ellipsospora. Based on the results of the morphological and molecular analyses, the fungal isolate was identified as P. ellipsospora. In Korea, this is the first report of canker on A. divaricatus.

Among them, compounds 3-4 and 9-11 were firstly isolated from the genus Nothopanax, and compounds 5-8 were isolated from this plant for the first time.

The genus Schefflera (Araliaceae) consists of 1100 species, 35 of which can be found in China. Some species of the genus have been used in traditional medicine to treat rheumatalgia, trauma, fracture, headache, and so on. Phytochemical studies of the genus have demonstrated the presence of large number of triterpenoids and their saponins, along with some long-chain compounds, steroids and sesquiterpenes. Furthermore, many pharmacological activities of the genus such as anti-inflammatory, anticancer and antiviral activities have been reported. In this article, new development of constituents and biological activities of Schefflera genus is reviewed and summarized for its further development and utilization.

OBJECTIVETo study active constituents of Macropanax rosthornii in treating rheumatoid arthritis.

METHODSilica gel column chromatography, preparative HPLC and modern spectrum techniques were applied for a systematic study on chemical constituents contained in M. rosthornii.

RESULTTwelve compounds were separated from M. rosthornii and identified as serratagenic acid (1), serjanic acid (2), betulinic acid (3), 6beta-hydroxy-3-oxo-olean-12-en-28-oic acid (4), 3-O-alpha-L-arabinopyranosyl serratagenic acid (5), 3-O-alpha-L-arabinopyranosyl serratagenic acid-29-methyl ester (6) , 3-O-alpha-L-arabinopyranosyl serratagenic acid-28-O-beta-D-glucopyranosyl ester (7), scopoletin (8), beta-sitosterol (9), daucosterol (10), 3,4-dihydroxybenzoic acid (11), and stearic acid (12).

CONCLUSIONAbove compounds are separated from M. rosthornii for the first time.

The purpose of our research was to evaluate the protective effect of the effective part of Acanthopanacis senticosus (AS) on the damage of PC12 cells induced by MPP+, an in vitro cell model for Parkinson's disease. Cell viability and apoptosis of PC12 cells induced by MPP' were assayed by MTT and flow cytometry respectively in the presence or absence of the effective part of AS. The contents of lactate dehydrogenase (LDH), nitric oxide (NO), nitric oxide synthase (NOS) and malondialdehyde (MDA) were determined by UV spectrophotometer. Our study showed that the survival rate of PC12 cells was markedly increased while cell apoptosis was decreased in the range of 200 to 400 mg x L(-1) of the effective part of AS. The contents of LDH, NO, NOS, MDA were reduced. Our experimental results indicated that the effective part of AS had the protective effect on the damage of PC12 cells induced by MPP+. The underlying mechanisms might be the combination of reduction of LDH leakage and decreases in the contents of NO, NOS and MDA, and finally prevent the apoptosis in PC12 cells and increase the cell survival rate.

Leaf spot and blight disease was observed on two-year-old seedlings of Dendropanax morbifera (Korean name: Hwangchil tree) during July of 2008 in Jindo Island, Korea. Symptoms included yellow-brown to dark brown irregularly enlarged spots frequently located along the veins of leaves. The lesions were often surrounded by chlorotic haloes. Severe leaf blight and subsequent defoliation occurred when conditions favored disease outbreak. The causal organism of the disease was identified as Alternaria panax based on morphological characteristics and sequence analysis of the internal transcribed spacer region of rDNA. A. panax isolates induced leaf spots and blight symptoms not only on D. morbifera but also on the other members of Araliaceae tested. This is the first report of foliar blight caused by A. panax on D. morbifera.

This study was conducted to investigate the effects of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts on blood hemoglobin, HbA1c levels and biomarkers in the streptozotocin (STZ)-induced diabetic rats. Male Wistar rats divided into normal and diabetic groups. The diabetic groups subdivided into the control group (DM) and Araliaceae water extracts supplemented groups: Aralia elata (AE), Acanthopanacis cortex (AC) and Ulmus davidiana (UD). The extracts were supplemented in diet base on 11.42 g of raw Araliaceae/kg diet for 7 weeks. The diabetes was induced by injecting STZ (55 mg/kg B.W., i.p.) once 2 weeks before sacrifying. Relative weights of liver were significantly lowered in the DM group compared to the normal group, whereas those of kidney and heart were significantly increased in the DM group. Supplementation of the Araliaceae water extracts improved reduced liver weights in STZ-induced diabetic rats. Blood glucose level was significantly higher in the DM group than in the normal group, whereas insulin contents were significantly lowered in the DM groups. However, these parameters were normalized in the AE, AC and UD supplemented groups, respectively. Blood hemoglobin and HbA(1c) levels were significantly higher in the DM group than in the normal group. When all of Araliaceae water extracts were supplemented to the diabetic rats lowered hemoglobin and HbAI(1c) levels. Red blood cell, white blood cell and lymphocyte were significantly higher in the DM group than in the normal group. The supplementation of Araliaceae family water extracts significantly lowered these parameters compared to the DM group. MCV, MCH contents were declined in the DM group, while the supplementation of Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts elevated of these contents in STZ-induced diabetic rats. Accordingly, these results indicate that Aralia elata, Acanthopanacis cortex and Ulmus davidiana water extracts would seem to improve the blood biomarkers in STZ-induced diabetic rats.
