  • Acanthopanax species are well known medicinal plants in Korea for their adaptogenic efficacy. Regarding to the botanical classification of Acanthopanax koreanum, an indigenous species in Jeju island of Korea, it has been classified as different species of Acanthopanax genus. However, the morphological characteristics of A. koreanum are very similar with other Acanthopanax species, especially with A. gracilistylus. In order to provide further classification information among these botanically related species, microscopic and morphological studies on these Acanthopanax species were performed. In this result, it has been found that A. koreanum is similar to A. gracilistylus in terms of anatomical observation and was distinguished from A. sieboldianus by their morphological and anatomical differences.

  • A new and two known lupane-triterpene glycosides were isolated from the hot MeOH fraction of the leaves of Acanthopanax gracilistylus W. W. Smith. Based on the physical properties and spectroscopic data, their chemical structures were determined as acankoreoside A (1), acankoreoside D (2), and $3{\alpha}-hydroxy-lup-23-al-20(29)-en-28-oic$ acid $28-O-{\alpha}-L-rhamnopyranosyl-(1{\rightarrow}4)-{$beta}-D-glucopyranosyl-(1{\rightarrow}6)-{\beta}-D-glucopyranosyl$ ester (3), respectively. To our best knowledge, compand 3 appears to be novel, which was named as wujiapioside A.

  • Ten compounds were isolated from the stem barks of Acanthopanax gracilistylus WW Smith (AGS) by steam distillation, they were p-menta-1,5,8-triene, n-butyl isobutylphthalate, p-mentha-1,5-diene-8-ol, 8-hydroxy-p-cymene, myrtenol, trans-(+)-carveol, 1,3-di-tert-butylbenzene, 4-methyl-2,6-di-butylphenol, valencene and verbenone, respectively, characterized by GS-Mass spectra. And we have also extracted and isolated from the MeOH extracts of the stem barks of AGS, two compounds were obtained. On the basis of chemical and spectral evidence, they were syringin(l), ${\beta}-sitosterol(2)$.

  • The activities on the inhibition of NO on LPS-induced RAW 264.7 macrophages were investigated in this work. A simple and sensitive method has been developed and validated for fingerprinting analysis of leaves of Acanthopanax gracilistylus W.W. Smith (AGS). The cytotoxicity and inhibition of NO on LPS-induced RAW 264.7 cells of the extract and triterpenoids were determined. Optimal conditions of HPLC analysis were established as follows. The separation was performed with an ODS-C18 column at $30^{\circ}C$, the detected wavelength was 210 nm, the flow rate was 1 mL/min, and the mobile phase consisted of acetonitrile (0.05% phosphoric acid)-0.05% phosphoric acid solution with gradient elution. Our results showed that impressic acid and acankoreaogenin was more effective on the inhibition of NO than the methanol extract and other compounds. There were seventeen peaks coexisted with similarities above 0.95 and nine lupane-triterpenoids including acankoreaogenin and impressic acid detected and identified. The result of anti-inflammatory activities provides a potential explanation for the use of AGS leaves as a herbal medicine in the treatment of inflammatory diseases. Our results also show that acankoreanogenin and impressic acid may be potentially useful in developing new anti-inflammatory agents. In addition, the fingerprint chromatography clearly illustrated and confirmed the material basis for the anti-inflammatory activities of this plant.

  • Inhibitory effects of 130 medicinal plants on hyaluronidase activity were analyzed. The medicinal plants are clinically used as herbal medicines for korean traditional prescriptions. Six out of the 130 herbal medicines exhibited more than 50% of inhibition on hyaluronidase activity by their total methanol extracts with 5mg/ml as a final concentration. The active total methanol extracts were prepared from cortex of Acantbopanax gracilistylus, lignum of Caesalpinia sappan, radix of Glycyrrhiza uralensis, radicis cortex of Morus alba, herba of Prunella vulgaris, and radix of Sanguisorba officinalis. These active total methanol extracts were sequentially fractionated with dichloromethane, ethyl acetate, n-butanol, and then water. Among the solvent-fractionated extracts, the butanol fractions of Acantbopanax gracilistylus and Glycyrrhiza uralensis with 1 mg/ml as the final concentration exhibited more than 50% of inhibition on hyaluronidase activity, and the other fractions with the same concentration did less than 20% of inhibition.

  • Thirty-two methanol extracts of thirty-one Vietnamese medicinal plants were evaluated for the cytotoxic activity against five human cancer cell lines, including A549, MCF-7, HT 1080, Huh-7, and HepG2. Of these, the nine extracts of Acanthopanax trifoliatus (4), Acanthopanax gracilistylus (5), Siegesbeckia orientalis (10), Betula alnoides (11), Passiflora edulis (18), Zanthoxylum simulans (leaf, 23), Adenosma caeruleum (26), Solanum verbascifolium (29), and Alpinia malaccensis (31), exhibited high potent cytotoxic activity showing a certain degree of selectivity against the different cell types, with $IC_{50}$ values ranging from 2.1 to $3.8\;{\mu}g/mL$.

  • Hypoglycemic effect through activity inhibition of $\alpha$-glucosidase and $\alpha$-amylase was evaluated using leaves of Eleutherococcus senticosu, Eleutherococcus gracilistylus, Eleutherococcus sieboldianus and Eleutherococcus sessiliflorus which belong to Acanthopanax sessiliflorus genus. As a result of measuring $\alpha$-glucosidase activity inhibition, extract of Eleutherococcus gracilistylus showed around 43.38% of activity inhibition compared with acarbose and extract of Eleutherococcus senticosu showed 41.24% inhibitory effect. As a result of measuring $\alpha$-amylase activity inhibition, acarbose showed 73.25% of activity inhibition in 10 mg/mL concentration, and the extract of Eleutherococcus senticosu leaves showed 91.90% higher activity inhibition compared with acarbose. Also, after subjects in a model were induced diabetes with streptozotocin (STZ) intake plant extract from Acanthopanax sessiliflorus for 2 weeks, effect of improving blood glucose level and fat was examined. In all groups with specimen, Eleutherococcus senticosu (T1), Eleutherococcus gracilistylus (T2), Eleutherococcus sieboldianus (T3) and Eleutherococcus sessiliflorus (T4), blood glucose level was significantly decreased compared with that in control group (C). In an experiment of examining changes in fat concentration in blood, total cholesterol content increased in a control group compared with a normal, while in T1, T3 and T4, it decreased significantly compared with the control group. As for HDL-cholesterol, it significantly increased in all diabetes induced groups compared with the normal group, and in T3, it increased the most significantly by 55.61% compared with the control group. In case of LDL-cholesterol, specific difference between the normal group and the control group was not found; however, significant increase was detected in T2 and T3, whereas in T1 and T4, it decreased significantly compared with the control group. As for triglyceride, its concentration increased in the control group like total cholesterol. It decreased 60.16% in T3, 60.80% in T4 and 50.16% in T1 compared with the control group. As a result of measuring the concentration of triglyceride in extracted liver, the control group showed significant increase compared with the normal group, whereas T1 and T2 showed significant decrease compared with the normal group. The above results show that extracts from Acanthopanax sessiliflorus genus are effective for hypoglycemic and improving fat metabolism due to diabetes.
