  • Objective : For the purpose of developing Magnoliaceae plants recorded in Korean Herbology in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. Methods : Books and research papers about Herbology which published at Korea and other countries were examined. Results : A list was made about Magnoliaceae plant which were cultivated or grew naturally in Korea, after investigated the data on domestic and foreign Magnoliaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Magnoliaceae's properties flavor, channels they use, effects, and toxicity were also noted. Magnoliaceae(grew in Korea) were divided into 5 classes with 16 species. Out of those, 3 classes with 5 species were found serviceable which indicates 32% of all. Out of all 16 species of Magnoliaceae family, Magnolia genus were found 7 species, which were shown the most. Among 3 genus of Magnolia species, medicinal plants were all one species each. Out of all serviceable parts in Magnoliaceae, Flos parts took first place as 3 species. There are no toxic, the survey said. Conclusion : There were totaled to 5 genera and 16 species in Magnoliaceae in Korea and among them medicinal plants are 3 genera, 5 species, some 32% in total.

  • Anatomical characters of secondary xylem in the trunk of Magnoliaceae, Winteraceae and Schizandraceae, including six genera and eleven species grown naturally in Korea, were studied to elucidate the relationship between genera or families. It is considered that among these families specialization in the perforation plate, the angel of end wall to the vessel axis, and diameter of vessel element, is in the order of Winteracae, Magnoliaceae, and then Schizandraceae. In Winteraceae, vessel elements have wholly scalariform perforation plates with very numerous bars. Among Magnoliaceae the peroration plates are scalariform with very numerous bars in Michelia, with few bars in Liriodendron, and with few bars or simple in Magnolia. In Schizandraceae, Schizandra shows scalariform perforation plates with few bars or simple perforation plates, and Kadsura shows almost simple ones.

  • Floral morphology of Magnoliaceae and Illiciaceae in Korea is investigated. Magnoliaceae has long and elongate floral axis where numerous stamens and pistils are pistils are spirally arranged, whereas Illiciaceae has short floral axis and pistils are arranged in a single whorl on the axis. The stamens are basically similar in both families; winged and broad filament, prominant connective, long sporangium, and no clear limitation between fertile and sterile parts, which are primitive characters in stamen. The ovaries are the conduplicate type, in both, with decurrent stigma, stigmatic surface confined to stylar position, and no distinct style. Magnoliaceae has one locule and two ovules, whereas Illiciaceae has one locule and one ovule. The ovule is anatropous or hemianatropus, and has bitegmic integument and crassinucellate nucellus.

  • Two sesquiterpenes (1 - 2), a tetralone (3), and two phenylpropanoids (4 - 5) were isolated from the stem bark of Magnolia obovata Thunberg (Magnoliaceae) through repeated column chromatography. Their structures were identified as ${\beta}-eudesmol$ (1), cryptomeridiol (2), 4R-4,8-dihydroxy-${\beta}-tetralone$ (3), trans-pcoumaryl aldehyde (4), and p-coumaric acid (5) on the basis of spectroscopic analysis including two dimensional NMR and mass. Compounds 1 - 3 were tested in vitro for their cytotoxic activity against the K562, HeLa, A549, and HCT116 cancer cell lines. However, compounds 1 - 3 were inactive in this assay system.

  • Five neolignans (1 - 4, 8), two sesquiterpene-lignans (5 - 6), and two phenylpropanoids (7, 9) were isolated from the stem bark of Magnolia obovata Thunberg (Magnoliaceae) by repeated column chromatography. The structures of isolated compounds were identified as 4-methoxyhonokiol (1), obovatol (2), magnolol (3), honokiol (4), eudeshonokiol B (5), eudesobovatol B (6), coumaric acid (7), magnaldehyde B (8), and ${\rho}-coumaric$ acid (9) on the basis of spectroscopic analysis including 2D-NMR and MS data. Compounds 1 - 9 were evaluated for their anti-complement activities against the classical pathway of the complement system. Of them, compound 8 showed significant anti-complement activity on the classical pathway with $IC_{50}$ value of 102.7 ${\mu}M$, whereas compounds 1 - 7 and 9 were inactive. This result indicated that an aldehyde group in the neolignan is important for the anti-complement activity against the classical pathway.

  • Three lignans were isolated from the fruit of Magnolia denudata (Magnoliaceae) through repeated column chromatography. Their chemical structures were elucidated as sesamin, kobusin and eudesmin, respectively, by spectroscopic analysis. These compounds were isolated for the first time from the fruit of Magnolia denudata.

  • Liriodendron tulipifera, belonging to the family Magnoliaceae, is commonly called tulip tree. Four N-acetylated aporphine alkaloids, N-acetylnornuciferine (1), N-acetylanonaine (2), N-acetyl-3-methoxynornuciferine (3), and N-acetyl-3-methoxynornantenine (4) were isolated from the roots of L. tulipifera. Although the purity of each compound (1 - 4) was determined to be 97, 96, 99, and 98%, respectively, the 1H and 13C NMR spectroscopic data of the aporphine alkaloids 1 - 4 displayed all signals in duplicate, indicating the presence of two rotamers due to restricted rotation of N-COCH3 functionality in solution status. The absolute configurations of 1 - 4 w ere established by measuring specific rotation and comparison with the reported data. This is the first report on the 1H and 13C NMR assignments of N-acetyl-3-methoxynornuciferine (3) and N-acetyl-3-methoxynornantenine (4). This study provides advanced NMR spectroscopic data for the structure determination of rotameric aporphine alkaloids.

  • The 90% methanol extracts of eight magnoliaceae plants were collected and tested the cytotoxicity against SK-OV-3 and SiHa cells. Also six pure compounds such as magnonol, honokiol, dihydroxybiphenyl ether, linodenine, anonaine, asimilobine which were previously isolated from Magnolia obovata Thunb. were evaluated the cytotoxicities and their mechanism study using the Lactate dehydrogenase assay(LDH) and FACScan analysis system. Of the tested six compounds, magnonol, honokiol, dihydroxybiphenyl ether showed high cytotoxicities against human cancer cell lines, SK-OV-3 and SiHa cells. In addition, one of the plausible mechanisms of their antitumor activities suggested that they could induce the early stage of apoptosis. For the quantitative analysis, the methanol extractives were fractionated with chloroform, ethylacetate, $H_2O$ and then the ethylacetate fraction was chromatographed on silica gel using n-Hexane ; Acetone(4:1, v/v) as eluent. This fraction was subjected for the quantitative analysis in the HPLC system. The result suggested that the methanol extractives of Magnolia obovata Thunb. contained with magnonol, honokiol, dihydroxybiphenyl ether, 0.9%, 0.3% and 0.24%, respectively.
