Four steroids have been isolated from the subterranean parts of Smilax nipponica Miquel (Liliaceae). The structures of these compounds were characterized on the basis of chemical and speectral data. They were $\beta$-sitosterol, $\beta$-sitosterol-3-O-$\beta$-D-glucopyranoside, neotigogenin-3-O-$\beta$-D-glucopyranoside and a new steroidal saponin designated as smilanippin A which was elucidated as neotigogenin-3-O-$\beta$-D-fucopyranosyl(1$\rightarrow$6)-$\beta$-D-glucopyranos ide.

Chinese crude drug 'To Bog Ryung' has been to cure chronic aperient, syphilis cough and diabetes. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of To Bog Ryung, the morphological and anatomical characteristics of the rhizomes of Smilax species growing in Korea, i.e. S. china, S. riparia var. ussuriensis, S. nipponica, S. sieboldii were compared. As a result, it was determined that To Bog Ryung was the rhizome of Smilax china and Smilax sieboldii.

In order to find out the values of the steroid resources for the future use, the compositions and contents of steroidal sapogenins from 13 domestic plants have been investigated. As a result Dioscorea nipponica, D. quinqueloba and Smilax china were found to have large amount of diosgenin. And pennogenin in Trillium kamtschaticum and Paris verticillata, yuccagenin in Allium fistulosum, hecogenin in Agave americana and neochlorogenin in Solanum nigum were appeared to be major steroidal sapogenins.

We have investigated the vegetation in the peninsula located in Ongjeong-Li Seomyeon in Youngweol-gun. Since this is a limestone area, boxtrees, Abelia mosanensis T. H. Chung ex Nakai, and Selaginella stauntoniana Spring were abundant, as these are types of vegetation characteristic of limestone areas. Pinus densiflora S. et Z. was the most dominant woody plant, but vegetational changes, such as the dominance of Quercus variabilis Blume, Quercus dentata Thunb, and Quercus mongolica Fischer, were observed in spots. In particular, the growth of nursery plants of pinus densiflora S. et Z. was not observed, and young trees like Quercus mongolica Fischer grow as low vegetation of Pinus densiflora S. et Z.. Thus, the ecological succession of Quercus mongolica Fischer is predicted. Outside the investigation area, as herbaceous plants, various vegetations were observed, including Selaginella stauntoniana Spring, Thalictrum coreanum H. Lev., Mukdenia rossii(Oliv.) Koidz., Platanthera freynii Kraenzl., Cephalanthera longibracteata Blume, Potentilla dickinsii Franch., Patrinia rupestris(Pall.) Juss., Swertia pseudochinensis H. Hara, Vicia venosa(Willd.)

Hara, Isodon inflexus(Thunb.) Kudo, Gentiana scabra Bunge for. Scabra, Polygonatum odoratum var. pluriflorum(Miq.) Ohwi, Dioscorea quinqueloba Thunb., Syneilesis palmata(Thunb.) Maxim., Asparagus schoberioides Kunth, Eupatorium japonicum Thunb. ex Murray, Galium kinuta Nakai & Hara, Saxifraga fortunei var. incisolobata, Lilium amabile Palib., Siberian iris, Dictamnus dasycarpus Turcz., Atractylodes ovata(Thunb.) DC., and Lysimachia clethroides Duby.
