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.

Two alkaloids were isolated from an ether-soluble alkaloidal fraction of Panax ginseng. They were identified as 1-carbobutoxy-$\beta$-carboline and 1-carbomethoxy-$\beta$-carboline.

Chemical constituents of fruits, leaves and barks of Acanthopanax senticosus forma inermis were studied. Their fruits have higher contents of crude ash, crude protein, crude fat, fructose and glucose than those of other Acanthopanax species, and contained larger amount of glutamic acid and malic acid among amino acid and organic acid, respectively. The compounds identified from their barks and leaves, were $\beta$-sitosterol and stigmasterol, sesamin, savinin, syringaresinol diglucoside, oleanolic acid, chiisanoside and polyacetytene ($C_9H_{10}O_2$, mp. 62~63).

A new dammarane glycoside named ginsenoside $Rf_{2}$ has been isolated from Korean red ginseng (Panax ginseng) and its chemical structure has been elucidated as $6-O-[{\alpha}-L-rham-nopyranosyl (1{\rightarrow}2){\beta}-D-glucopyranosyl]$$dammarane-3{\beta}, 6{\alpa}, 12{\beta}$, 20(R), 25-pentol by chemical and spectral methods.

Acanthopanax species (Araliaceae) has been traditionally used as analgesics, stimulants of immune system, and replenishment of body functions. Acanthopanax divaricatus var. albeofructus is a indigenous plant in Korea. The anti-lipid peroxidation activities of the loaves and root bark extracts of A divaricatus var. albeofructus were determined. Activities of MeOH extracts were examined in vitro and in vivo with control group intoxicated by carbon tetrachloride. Both extracts showed significant inhibitory effects on the lipid peroxidation.

This study investigated the effect that some polyacetylenes and protopanaxatriol, which were isolated from heated ginseng (family Araliaceae), have on inhibiting Helicobacter pylori (HP) growth. Among the compounds tested, panaxytriol was quite effective in inhibiting HP growth with an MIC of 50 ${\mu}g/ml$. Cinsenoside Rhl and protopanaxatriol weakly inhibited $H^{+}/K^{+}$-ATPase from a rat stomach.

Acanthopanax species (Araliaceae) has been traditionally used as tonic, analgesic, stimulant of immune system, and replenishment of body function. The antioxidant activities of leaf and root bark of Acanthopanax species were determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and thiobarbituric acid reactive substances (TBARS) assay and relative electrophoretic mobility (REM) on human plasma low density lipoproteins (LDL). Acanthopanax divaricatus var. albeofructus and Acanthopanax for. nambunensis showed potent antioxidant activities.
