Three diterpenes (1, 8, and 9), three triterpenes (3, 4, and 7), one saponin (11), four sterols (2, 5, 6, and 12), and one cerebroside (10) were isolated from the EtOH extract of the aerial parts of Aralia cordata by repeated silica gel column chromatography. Their chemical structures were identified by comparing their physicochemical and spectral data with those published in literatures. All isolated compounds were evaluated for their cytotoxicity against L1210, K562, and LLC tumor cell lines using MTT assay. Of which, $3{\beta},5{\alpha}-dihydroxy-6{\beta}-methoxyergosta-7,22-diene$ (6) showed a potent cytotoxicity against all cell lines with $IC_{50}$ values of 11.7, 11.9, and $15.1\;{\mu}M$, respectively, while compounds 1, 5, and 11 showed a moderate or weak cytotoxicity. These isolates were also examined for their inhibitory activity against COX-1 and COX-2. Although most compounds, except for 2, 10, and 12, showed a strong inhibitory activity against COX-1, they exhibited a moderate or weak inhibitory activity against COX-2.

An n-hexane extract of the roots of Aralia cordata Thunb. (Araliaceae) was found to show significant in vitro cytotoxic activity against P388D$_{1}$ lymphocytic leukemia cell in culture. Bioactivity-directed fractionation of this extract led to the isolation of four polyacetylenes, falcarindiol (1), dehydrofalcarindiol (2), falcarindiol-8-acetate (3) and dehydrofalcarindiol-8-acetate (4). Cytotoxicity of compounds 1 and 3 was found to be better than that of compounds 2 and 4 when these compounds were tested against eight in vitro tumor cell lines, namely, A549, HCT15, DLD1, MCF7, SKOV3, HL60, K562 and P388D$_{1}$. The fact that the cytotoxicity of compounds 1 and 3 against series of tumor cell lines was much stronger than that of compounds 2 and 4 suggested that the saturated carbon chain at the termial and the hydroxyl group at the C-3 are important for the activities. The requirement for the activity was further confirmed by synthesizing and assaying the acetate derivatives of compounds 1 and 2.

A simple and reliable reversed phase HPLC method was developed to determine pharmacologically active compounds ent-continentalic acid, kaurenoic acid, and continentalic acid from the roots of Aralia cordata. Quantitative analysis of diterpenoids of A. cordata were performed by reverse phase C-18 column using a isocratic of acetonitrile : 0.1% trifluoroacetic acid(70:30) with UV detection at 205 nm. The correlation coefficients of each calibration curve of ent-continentalic acid, kaurenoic acid, and continentalic acid were 0.9987, 0.9983, and 0.9986, respectively. The detection limit of ent-continentalic acid, kaurenoic acid, and continentalic acid were $0.5{\sim}1.0\;{\mu}g/mL$, respectively. The contents of ent-continentalic acid (1), kaurenoic acid (2), and continentalic acid (3) of the roots of A. cordata collected from seventeen district markets in Korea were $0.09{\sim}0.75\;mg/g$, $1.09{\sim}5.43\;mg/g$, and $2.69{\sim}9.08\;mg/g$, respectively.

This study was carried out to investigate the growth responses of medicinal plants such as Glehnia littoralis, Cryptotaenia japonica, Angelica gigas, Reynoutria japonica, Saururus chinensis, Houttuynia cordata, Ligularia fischeri, and Aralia cordata under 70%-shading and full sunlight conditions on a rooftop condition using artificial soil as a growth media. Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordata showed better growth on plant height, leaf length, leaf width, petiole length and leaf number under full sunlight conditions on a rooftop condition. Cryptotaenia japonica and Houttuynia cordata had high value of Hunter's a (red-green) under full sunlight, while had lower value of L(lightness) and b(blue-yellow) than those of 70% shading condition. As an index of plant stress response, Glehnia littoralis, Reynoutria japonica, Houttuynia cordata, Ligularia fischeri showed Fv/Fm values 0.79~0.84 under full sunlight in August, indicating low stress on plant growth. Therefore they seemed to be suitable medicinal plats for rooftop conditions. Ligularia fischeri and Reynoutria japonica showed better growth under 70% shading treatment in August, while showed high growth response under full sunlight conditions in September. The 70% shading treatment was effective for the growth of Angelica gigas, Reynoutria japonica, and Aralia cordata. Angelica gigas and Reynoutria japonica, however, showed better plant growth under full sunlight during summer. The results showed that Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordat seemed to be suitable medicinal plants for rooftop garden where there is a full sunlight condition.

Seven diterpenes, four polyacetylenes, a lipid glycerol, and two sterols were isolated from the methylene chloride fraction of the root of Aralia cordata. Their chemical structures were determined as (-)-pimara-8(14), 15-dien-19-oic acid (2), pimaric acid (3), (-)-kaur-16-en-19-oic acid (4), 17-hydroxy-ent-kaur-15-en-19-oic acid (9), $7{\alpha}$-hydroxy-(-)-pimara-8(14), 15-dien-19-oic acid (10), $16\alpha$, 17 -dihydroxy-(-)-kauran-19-oic acid (11), 16-hydroxy-17-isovaleroyloxy-ent-kauran-19­oic acid (12), falcarindiol (5), dehydrofalcarindiol (6), dehydrofalcarindiol-8-acetate (7), falcarin­diol-8-acetate (8), alpha-mono palmitin (13), stigmasterol (1), and daucosterol (14) by the spectral evidences. These compounds were tested with COX-1 and COX-2 inhibition assays. This study found that compounds 2, 4, 5, 6, 7, 8, and 10 inhibited COX-1 dependent conversion of the exogenous arachidonic acid to $PGE_2$ in a dose-dependent manner with $IC_{50}$ values of $134.2{\mu}M$, $121.6{\mu}M$, $170{\mu}M$, $50.4{\mu}M$, $11.7{\mu}M$, $99.6{\mu}M$, and $69.6{\mu}M$, respectively. But, most of these compounds weakly inhibited COX-2 dependent $PGE_2$ generation. Among them, only compound 4 showed relatively significant inhibitory activity $(IC_{50}\;:\;127.6{\mu}M)$.

The present study investigated an ethanol extract (SSB) of a mixture of three medicinal plants of Vitis amurensis, Aralia cordata, and Glycyrrhizae radix for possible neuroprotective effects on neurotoxicity induced by Amyloid ${\beta}$ protein ($A{\beta}$) (25-35) in cultured rat cortical neurons and antidementia activity in mice. Exposure of cultured cortical neurons to $15{\mu}M$ $A{\beta}$ (25-35) for 36 h induced neuronal apoptotic death. At $1-30{\mu}g/m{\ell}$, SSB inhibited neuronal death, elevation of intracellular calcium concentration ($[Ca^{2+}]_i$), and generation of reactive oxygen species (ROS) induced by $A{\beta}$ (25-35) in cultured cortical neurons. Memory impairment and increase of acetylcholinesterase activity induced by intracerebroventricular injection of mice with 16 nmol $A{\beta}$ (25-35) was inhibited by chronic treatment with SSB (25, 50 and 100 mg/kg, p.o., for 8 days). From these results, it is suggested that antidementia effect of SSB is due to its neuroprotective effect against $A{\beta}$ (25-35)-induced neurotoxicity and that SSB may have a therapeutic role in preventing the progression of Alzheimer's disease.
