The rhizomes of the Acorus gramineus Soland have been used as sedatives, analgesics, stomachics and anthelmintics in chinese medicine. It is known that the rhizomes of the Acorus gramineus Soland contains the essential oil about 0.5~0.8% and this essential oil contains asarone about 86%. The asarone possess many pharmacological properties similar to those of reserpine and chlorpromazine. Sedative and analgesic effects of essential oil of Acorus gramineus Solaad in mouse was observed. The essential oil of Acorus gramineus Soland decreased the frequency of ambulation on mouse in proportion of concentration. ${\alpha}_2$ receptor antagonist(yohimbine hydrochloride) and opioids receptor antagonist(naloxone hydrochloride) were markedly decreased in frequency of ambulation. The essential oil of Acorus gramineus Soland decreased writhing syndrome in mouse and ${\alpha}_2$ receptor antagonist(yohimbine hydrochloride), opioids receptor antagonist(naloxone hydrochloride) were not increased above effects. In conclusion, these experimental results show that the essential oil of Acorus gramineus Soland have sedative and analgesic effects, but it did not antagonized ${\alpha}_2$ receptor antagonist(yohimbine hydrochloride) and opioids receptor antagonist(naloxone hydrochloride).

We investigated the antithrombotic effect of Acorus gramineus Soland (A. gramineus) from Korea and Acorus tatarinowii Schott (A. tatarinowii) from China in a rat model of arterial thrombosis induced by ferric chloride ($FeCl_3$). Thirty minutes prior to a 35% $FeCl_3$ application, Sprague Dawley rats were intraperitoneally injected with saline, A. gramineus and A. tatarinowii (100 mg/kg), respectively. Occlusion time of rats injected with A. gramineus was delayed significantly compared to that of the vehicle and A. tatarinowii. Thrombus weight was meaningfully decreased in rats injected with A. gramineus compared to the vehicle. Additionally, A. gramineus inhibited collagen fiber damage in vessel compared to the vehicle, but A. tatarinowii did not show a significant effect. Our results show that A. gramineus and A. tatarinowii from the same genus have different antithrombotic effects, and especially A. gramineus has a better antithrombotic effect than A. tatarinowii.

Background & Objectives : Rhinitis is an inflammation of nasal mucosa. The major symtoms are watery rhinorrhea, sneezing, itchy nose, and nasal obstruction. Allergic rhinitis is an immune reaction by allergen. So, we aimed to determine therapeutic effects of Acorus gramineus by observing changes in IL-4, $IFN-{\gamma}$ and the nasal mucosal tissue. Materials and Methods : Fifteen BALC/c mice were divided into three groups : m group(which ate low concentrated herbal medicine ), M group(which ate high concentrated herbal medicine) and control group. Control and experimental group were induced allergic rhinitis by Ovalbumin as the method of Levin and Vaz. Experimental group was orally administered the Acorus gramineus extract for 28days. We observed changes in IL-4, $IFN-{\gamma}$ and trans aminase(AST, ALT) in blood and nasal mucosa and submucosa. Results : There were no significant changes statistically in IL-4 and $IFN-{\gamma}$ in blood(p<0.05). And there were no hepatotoxicity with Acorus gramineus extract. Histologically, almost no inflammatory response in treatment group(m,M) against that there were inflammatory response(increased goblet cells, dilated vessels, edema of bowman's glands and injured olfactory hairs) in control group. Conclusion : According to above results, it is supposed that Acorus gramineus has no immunological effects on allergic rhinitis.

This paper was investigated to know that the effect and mode of action of essential oil of Acorus calamus L. and Acours gramineus Soland on motility of isolated rabbit jejunum segment. The results were as follows : 1. Both essential oil of Acorus calamus L. and Acorus gramineus Soland were showed relaxant effect on motility of isolated rabbit jejunum segment and this relaxant effect was augmentated in proportion to increase of concentration of essential oil. 2. ED 50 of essential oil of Acorus calamus L. and Acorus gramineus Soland were 0.0045%, 0.0035%, respectively. 3. The relaxed rabbit jejunum segments by eseential oil of Acorus calamus L. and Acorus gramineus Soland were recovered by carbachol, pilocarpine, and barium chloride but partially recovered by histamine. 4. The contracted rabbit jejunum segmants by carbachol, pilocarpine, histamine and barium chloride were relaxed by essential oil of Acorus calamus L. and Acorus gramineus Soland. In conclusion, it is thought that essential oil of Acorus calamus L. and Acorus gramineus Soland were relaxed the motility of isolated rabbit jejunum segment by neurotropic and musculotropic action.

The genus Acorus is known as an indigenous medicinal plant. Genetic diversity of thirteen accessions of A. calamus and eight of A. gramineus, with an accession of Colocasia antiquorum and two of Iris pseudacorus as outgroups, were evaluated using RAPD markers for cluster analysis and principal coordinate analysis, and NIR spectroscopic profiles for principal component analysis.A total of 371 polymorphic bands were obtained by using the selected 12 random primers. The genetic distances were estimated from 0.03 to 0.31 within A. calamus and from 0.03 to 0.51 within A. gramineus. The dendrogram and three-dimensional plot separated the accessions into four distinct groups (A. calamus, A. gramineus, C. antiquorum, and I. pseudacorus). Moreover, for the diversity among genus Acorus, eleven A. calamus accessions, one A. gramineus accession, and two I. pseudacorus accessions were non-destructively analyzed from their leaves by NIR spectroscopy, which discriminated Acorus accessions like the RAPD analysis. Interestingly, thirteen accessions of A. calamus were clustered into two groups based on RAPD and NIR analyses, which indicates that there are two ecotypes of A. calamus in Korea. An accession (CZ) of A. calamus with yellow stripe on leaves was closely grouped with another (CX) at a genetic distance (GD) of 0.03, which shows that the stripe trait might be generated by chimeric mutation. The genetic distance between A. calamus and A. gramineus was revealed to be farthest from 0.80 to 0.88 GD. In genus Acorus the genetic diversity and genetic variation were identified by using RAPD marker technique and non-destructive NIRs.

Objectives : Acori Rhizoma is one of the common widely used herbal medicines with diverse bioactive effects. However, little evidence has been reported about the potential anti-platelet activity of Acori Rhizoma. The present study examined the effects on platelet aggregation by Acori Rhizoma. Methods : In this study, we tested the in vitro effect of 16 kinds of Acori Rhizoma extracts by hot water or 70% ethanol on collagen-induced platelet aggregation in human whole blood using the impedance method of aggregometry. Results : Among them, 2 kinds of 70% ethanol extract and 1 kind of hot water extract showed the significant inhibiting effect on whole blood aggregation. In particular, Acorus gramineus extracts were selected as the most effective candidate. Conclusiions : The results from this experiment provide pharmacological evidence for the traditional medicine, suggesting that Acorus gramineus could be help problems of blood circulation more than Acorus tatarinowii.

The rhizomes of Acorus gramineus have frequently been used in traditional medicine mainly for sedation as well as enhancing brain function. In this study, the anti-allergic activity of A. gramineus was investigated. The 70% ethanol extract of the rhizomes of A. gramineus was found to inhibit the allergic response against 5-lipoxygenase (5-LOX)-catalyzed leukotriene (LT) production from rat basophilic leukemia (RBL)-1 cells and ${\beta}$-hexosaminidase release from RBL-2H3 cells with $IC_{50}$'s of 48.9 and > $200{\mu}g/ml$, respectively. Among the 9 major constituents isolated, ${\beta}$-asarone, (2R,3R,4S,5S)-2,4-dimethyl-1,3-bis (2',4',5'-trimethoxyphenyl)tetrahydrofuran (AF) and 2,3-dihydro-4,5,7-trimethoxy-1-ethyl-2-methyl-3-(2,4,5-trimethoxyphenyl)indene (AI) strongly inhibited 5-LOX-catalyzed LT production in A23187-treated RBL-1 cells, AI being the most potent ($IC_{50}=6.7{\mu}M$). Against ${\beta}$-hexosaminidase release by antigen-stimulated RBL-2H3 cells, only AI exhibited strong inhibition ($IC_{50}=7.3{\mu}M$) while ${\beta}$-asarone and AF showed 26.0% and 39.9% inhibition at $50{\mu}M$, respectively. In addition, the ethanol extract of A. gramineus showed significant inhibitory action against the hapten-induced delayed hypersensitivity reaction in mice by oral administration at 200 mg/kg. Therefore, it is suggested that A. gramineus possesses anti-allergic activity and the constituents including ${\beta}$-asarone and AI certainly contribute to the anti-allergic activity of the rhizomes of A. gramineus.
