From the BuOH Fr. of the roots of Acanthopanax koreanum $N_{AKAI}$, we have isolated a lignan glucoside, mp $257{\sim}259^{\circ}$, $C_{34}H_{46}O_{18}$ and it was identified to be (-) syringaresinol diglucoside by spectral data and comparing with authentic samples.

치면세균막내의 미생물 중 Streptococcus mutans $N_{AKAI}$는 치면세균막형성에 가장 중요한 역할을 하는 원인균으로 알려져 있으며, Streptococcus mutans $N_{AKAI}$는 치아우식을 일으키는 주요 원인균으로 주목을 받고 있다. Streptococcus mutans $N_{AKAI}$균에 항균효과를 나타내는 화합물 acanthoic acid (AA, $C_{20}H_{30}O_2$)을 Acanthopanax koreanum $N_{AKAI}$의 클로로포롬 추출물에서 각종 컬럼크로마토그래피법으로 추출분리하여 ms, 1H-NMR 그리고 13C-NMR 등을 이용하여 구조를 동정하였다. AA의 Streptococcus mutans $N_{AKAI}$에 대한 최소억제농도(MIC)와 최소살균농도(MBC)를 조사하였으며, 이 때 각각 2와 $4\:{\mu}g/mL$을 나타냈었다. 또한 다른 천연물에서 분리된 화합물인 tanshinone IIA는 8/16\;${\mu}g/mL$, 녹차의 추출물과 eucalyptoi은 $250/500\;{\mu}g/mL$이었다. 그리고 또 다른 치주질환의 원균인 Streptococcus sobrinus $N_{AKAI}$, Streptococcus sanguis $N_{AKAI}$ 및 Streptococcus gordonii $N_{AKAI}$의 최소억제 농도의 범위는 $4{\sim}32\;{\mu}g/mL$이었다. 우리의 연구결과에서 Acanthopanax koreanum $N_{AKAI}$에서 분리한 acanthoic acid 치주질환 원인균들을 억제하는 항균제로의 가능성을 확인하였다.

1. The Korean Acanthopanax genus includes 12 kinds consisting of 9 species and 3 forma. 2. The Korean Oga-pi which is on market sale has been used as bark for the medicinal purpose, and Oga-pi shall use Radicis Cortex. That is why it is basic rule that herbalogy shall use Radicis Cortex. 3. The origin of Oga-pi on sale is Acanthopanax sessiliflorum forma chungbunensis C.S. Yook. 4. $C_{HUNG}\;and\;N_AKAI'S}$ report on A. koreanum told us that there are brown hair on the mid-leaf junction, but in addition to it, our investigation was resulted in the fact that there are thorn along mid-rib sometimes. 5. 2 kinds of new forma are similar to A. sessiliflorum, but are different in the view-point of chemotaxonomy, compared with A. sessiliflorum. In its morphology, we can find some difference between 2 kinds of new forma and A. sessiliflorum. Our effort of examination on documents tell us that the all plants growing in the central part of our country is A. sessiliflorum forma chungbunensis C.S. Yook. The one which has thorn on both side among the plants collected in Mt. Dukyu, is called A. sessiliflorum forma nambunensis C.S. Yook. 6. A. sessiliflorum is growing in the southern part in Korea, and most Chungbu Oga-pi A. sessiliflorum forma chungbunensis in the central part of our country. For the convenience of our study, the key of Korean Acanthopanax plant is classified into, I-IV, as shown on the following items: I. No hair on both side of leaf A. Flower stalk is longer than petiole, and there are thorn under the petiole (5-7 stigma).${\cdots}A.\;sieboldianum$. B. Flower stalk is longer than petiole, or same length. The serration lie down, and the stem has short thorn (stigma is divided into 3 part).${\cdots\;\cdots}A.\;seoulense$ II. There are a lot of thorn or hair on back of leaf. A. A lot of thorn and hair on the vein of leaf back, and a number of small thorn on petiole.${\cdots}A.\;chiisanensis$. B. There are thorn on the vein of leaf back.${\cdots\;\cdots}A.\;sessiliflorum\;forma\;chungbunensis.$ III. There are hairs on both side of leaf. A. There are small hairs on the back of leaf.${\cdots\;\cdots}A.\;sessiliflorum.$ B. There are small hairs on both side of leaf.${\cdots\;\cdots}A.\;sessiliflorum\;f.\;nambunensis.$ C. There are thick hairs on junction of main vein on back of leaf.${\cdots\;\cdots}A.\;koreanum.$ D. There are brown hairs on vein of leaf back, and brown hairs on small petiole.${\cdots\;\cdots}A.\;rufinerve.$ E. There are shrunk hairs in grey-brown on back of leaf, and tense hairs on new branch (one stigma).${\cdots\;\cdots}A.\;divaricatum.$ IV. There are long thorn, just like needles, on the stem and petiole. A. Long needle grows on whole stem tensely, and long needles on petiole.${\cdots\;\cdots}A.\;senticosus.$ B. There are no needles, just like needles aid hairs on petiole, and needles grow on the stem thinly.${\cdots\;\cdots}A.\;asperatus.$ C. There are no needle on small brarch, leaf and inflorescence are larger than A. senticosus. ${\cdots\;\cdots}A.\;senticosus\;forma\;inermis.$.
