Four essential oils from the leaf (P23) and rhizomes (P19, P22, P24) of Acorus calamus L., collected from various parts of Nepal, were obtained by hydrodistillation and analyzed by GC-MS. From a total of 61 peaks, 57 compounds were identified among the four essential oils accounting for 94.3%, 96.2%, 97.6%, and 94.1% of the oils, respectively. All of the essential oils were dominated by (Z)-asarone (78.1%-86.9%). The essential oils also contained (E)-asarone (1.9%-9.9%) and small amounts of gamma-asarone (2.0-2.3%), (Z)-methyl isoeugenol (1.5-2.0%), and linalool (0.2-4.3%). Allelopathic testing of the rhizome oil showed inhibition of seed germination of Lactuca sativa and Lolium perenne with IC50 values of 450 and 737 microg/mL, respectively. The rhizome essential oil demonstrated stronger seedling growth inhibition of L. perenne than of L. sativa, however. The rhizome oil also showed notable brine shrimp lethality (LC50 = 9.48 microg/mL), cytotoxic activity (92.2% kill on MCF-7 cells at 100 microg/mL), and antifungal activity against Aspergillus niger (MIC = 19.5 microg/mL).
从尼泊尔各地采集的菖蒲叶(P23)和根茎(P19、P22、P24)中提取了四种精油,通过水蒸馏法获得,并采用气相色谱 - 质谱联用仪进行分析。在总共61个峰中,四种精油中共鉴定出57种化合物,分别占精油的94.3%、96.2%、97.6%和94.1%。所有精油均以(Z)-细辛脑为主(78.1%-86.9%)。精油中还含有(E)-细辛脑(1.9%-9.9%)以及少量的γ-细辛脑(2.0 - 2.3%)、(Z)-甲基异丁香酚(1.5 - 2.0%)和芳樟醇(0.2 - 4.3%)。根茎精油的化感测试表明,它对莴苣和黑麦草种子萌发有抑制作用,IC50值分别为450和737μg/mL。然而,根茎精油对黑麦草幼苗生长的抑制作用比对莴苣更强。根茎精油还表现出显著的卤虫致死性(LC50 = 9.48μg/mL)、细胞毒性活性(在100μg/mL时对MCF - 7细胞的杀伤率为92.2%)以及对黑曲霉的抗真菌活性(MIC = 19.5μg/mL)。
