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.

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.

Neurological disorders represent a substantial healthcare burden worldwide due to population aging. Acorus gramineus Solander (AG) and Acorus tatarinowii Schott (AT), whose major component is asarone, have been shown to be effective in neurological disorders. This review summarized current information from preclinical and clinical studies regarding the effects of extracts and active components of AG and AT (e.g., α-asarone and β-asarone) on neurological disorders and biomedical targets, as well as the mechanisms involved. Databases, including PubMed, Embase, and RISS, were searched using the following keywords: asarone, AG, AT, and neurological disorders, including Alzheimer's disease, Parkinson's disease, depression and anxiety, epilepsy, and stroke. Meta-analyses and reviews were excluded. A total of 873 studies were collected. A total of 89 studies were selected after eliminating studies that did not meet the inclusion criteria. Research on neurological disorders widely reported that extracts or active components of AG and AT showed therapeutic efficacy in treating neurological disorders. These components also possessed a wide array of neuroprotective effects, including reduction of pathogenic protein aggregates, antiapoptotic activity, modulation of autophagy, anti-inflammatory and antioxidant activities, regulation of neurotransmitters, activation of neurogenesis, and stimulation of neurotrophic factors. Most of the included studies were preclinical studies that used in vitro and in vivo models, and only a few clinical studies have been performed. Therefore, this review summarizes the current knowledge on AG and AT therapeutic effects as a basis for further clinical studies, and clinical trials are required before these findings can be applied to human neurological disorders.

The purpose of this study was to introduce the differential standard of the types of Acori Graminei Rhizoma. We established the classificatory standard according to the external and internal morphology for the several types of Acori Graminei Rhizoma. 1. External shape: Acorus gramineus has smaller size and fibroidal section. A. calamus has bigger size and cancellate section. A. tatarinowii has middle size and fibroidal section. Anemone altaica has very small long-spindle shape and flat section that has 6-12 row of vascular bundle. 2. Internal shape: Acorus gramineus has some bundle sheath fiber, but A. calamus has not. A. tatarinowii has many calcium oxalate crystalloid around bundle sheath. Anemone altaica has obscure cambium. All sample except A. altaica, in the mass, has scattered bundle, thin cell wall, broad cortex and well-developed endodermis. For the future, such results will be used as the basic source of additional research, and a far-reaching comparative study is needed to distinguish between many kinds of same genus-degree of relatedness.

Objective : This study was to compare antioxidant activity and HPLC pattern analysis from 4 species of changpo(ch$\={a}$ngp$\'{u}$). Methods : To compare the antioxidant activity and HPLC pattern analysis from the 4 species of changpo, we performed the in vitro anti-oxidative activity assays and HPLC analysis from 70% ethanol extracts of Acorus gramineus Sol. (=AG), A. tatarinowii Schott (=AT), A. calamus L. (=AC) and Anemone altaica Fisch. ex C.A.Mey (=AA) taken in the herbal medicine market of Korea. Results : AG has the most effective anti-oxidative activity among 4 species of changpo. As the HPLC pattern analysis, AT was detected the unknown peak at retention time 14.9 min whereas AG was not showed any peak at the same retention time. These results suggest that AG could be used rather than AT when it need to be prescribed as anti-oxidative medicine. Conclusions : This result can be used as the basic data contributing to the stability of AG according to an appropriate clinical application.

An effective analytical method of gas chromatography/mass spectrometry (GC/MS) was developed for the rapid determination of essential oils in the crude extract of Acorus species (Acorus gramineus, Acorus tatarinowii, and Acorus calamus). Major phenypropanoids (${\beta}$,${\alpha}$-asarone isomers, euasarone, and methyleugenol) and ${\beta}$-caryophyllene in Acorus species were used as marker compounds and determined for the quality control of herbal medicines. To extract marker compounds, various extraction techniques such as solvent immersion, mechanical shaking, and sonication were compared, and the greatest efficiency was observed with sonication extraction using petroleum ether. The dynamic range of the GC/MS method depended on the specific analyte; acceptable quantification was obtained between 10 and 2000 ${\mu}g/mL$ for ${\beta}$-asarone, 10 and 500 ${\mu}g/mL$ for ${\alpha}$-asarone, 10 and 200 ${\mu}g/mL$ for methyleugenol, and between 5 and 100 ${\mu}g/mL$ for ${\beta}$-caryophyllene. The method was deemed satisfactory by inter- and intra-day validation and exhibited both high accuracy and precision, with a relative standard deviation < 10%. Overall limits of detection were approximately 0.34-0.83 ${\mu}g/mL$, with a standard deviation (${\sigma}$)-to-calibration slope (s) ratio (${\sigma}$/s) of 3. The limit of quantitation in our experiments was approximately 1.13-3.20 ${\mu}g/mL$ at a ${\sigma}$/s of 10. On the basement of method validation, 20 samples of Acorus species collected from markets in Korea were monitored for the quality control. In addition, principal component analysis (PCA) and hierarchical cluster analysis (HCA) were performed on the analytical data of 20 different Acorus species samples in order to classify samples that were collected from different regions.

The rhizomes and herbal medicines originating from Acorus gramineus, A. calamus, A. tatarinowii, and A. gramineus var. pusilus, show significant similarity, and the correct identification of species is very difficult. Random Amplified Polymorphic DNA (RAPD) and Sequence Characterized Amplified Region (SCAR) were used to develop a reliable method for identification of these four species. Several distinct SCAR markers were developed from species-specific RAPD amplicons for each species. Furthermore, a useful molecular marker was established for multiplex-PCR, in order to the four species could be distinguished concurrently. These markers allow efficient and rapid identification of closely-related Acorus species and will be useful for standardization of herbal medicines.
