stems of Acer tegmentosum Max were extracted with MeOH and then partitioned with CH2Cl2, n-BuOH, andH2O, successively. Three compounds were isolated from the CH2Cl2 fraction through repeated column chromatographic sep-aration. Their chemical structures were elucidated as β-sitosterol, β-sitosterol-3-O-β-D-glucoside, and epifriedelinol by com-parison of spectral data with those in references. These three compounds were firstly isolated from this plant.Acer tegmentosum, sterol, epifriedelinol .. , .... .... ... ... ..... ... ... (Acer ginnala), ..... (A. mono), ..... (A. trncatum), .....

Breast edema is defined as a mammographic pattern of skin thickening, increased parenchymal density, and interstitial marking. It can be caused by benign or malignant diseases, as a result of a tumor in the dermal lymphatics of the breast, lymphatic congestion caused by breast, lymphatic drainage obstruction, or by congestive heart failure. Here we describe several conditions, that cause unilateral breast edema with the aim of familiarizing radiologists with these disease entities.

Regarding chemical changes in oriental drugs after food processing such as roasting, fermentation, and extrusion, fifty commonly-used medicinal plants were investigated. As a result, Aurantii nobilis Pericarpium (a tangerine peel from Citrus unshu Markovich) showed remarkably different HPLC profiles after being roasted. An increased peak was isolated by repeated chromatography and identified as 5-hydroxymethyl furfral (5-HMF) by means of instrumental analyses. The 5-HMF content of Aurantii nobilis Pericarpoum reached its maximum level after being roasted for 30 min at 225$^{\circ}C$ (49.2 mg/g extract, ca 42 times of increase over untreated control). Although there were no significant changes in in vitro biological activity such as antioxidative, anti-dementia, anti-hypertension, anti-coagulation, or cytotoxicity, before and after roasting process, our results suggested that simple heat treatment might improve the value of the above oriental drug since 5-HMF has been known to possess inhibitory activities toward nitric oxide formation, tyrosinase, and sickling of red blood cells.
