Objective: The present study was designed to study and compare the antibacterial and antioxidant activity of methanol extracts of Amomum subulatum Roxb. seeds collected from two different regions of Nepal.Methods: Antioxidant activity was determined by 1, 1-diphenyl-2-picrylhydrazyl assay and Antibacterial activity was measured by agar well-diffusion method. Results:Results showed that both sample extracts had interesting antibacterial activity against all test microorganisms and had remarkable radical scavenging potential to be used as an antioxidant. Sample B (i.e., collected from high altitude Taplejung district) exerted comparative quit higher antimicrobial and antioxidant activity than the Sample A (i.e., is collected from low altitude Panchthar district). However, the standard antibacterial drug Tetracycline exhibits superior activity than the extracts. Conclusions:The results suggest that both samples (i.e., seed extract of A. subulatum Roxb.) possess almost similar moderate antibacterial and antioxidant activity in comparison to standards which justifies the traditional use of this plant.

“…It has been reported that in the chemical composition of different species of cardamoms, monoterpenes are the main compounds [ 14 , 17 , 20 , 21 , 22 ]. Also, antimicrobial activity of the cardamoms is reported [ 23 , 24 ]. On black cardamom, 1,8-cineole is the main component [ 15 , 25 ].…”

To highlight the importance of the spices in the Mediterranean diet, the aim of the paper was to study the essential oil compositions and to clarify the potential differences in the biological activities of the three cardamom species. In the study, we compared the phytochemical profiles and biological activities of essential oils from Elettaria cardamomum, Aframomum corrorima and Amomum subulatum. The oils were analyzed using the GC and GC/MS techniques and were mainly constituted of the oxygenated monoterpenes which represents 71.4%, 63.0%, and 51.0% of all compounds detected in E. cardamomum, A. corrorima and A. subulatum essential oils, respectively, 1,8-cineole was the main common compound between the tree tested volatile oil. The essential oils showed significant antimicrobial activity against Gram-positive and Gram-negative microorganisms tested especially the fungal strains. The Ethiopian cardamom was the most active essential oil with fungal growth inhibition zone ranging from 12.67 to 34.33 mm, MICs values ranging from 0.048 to 0.19 mg/mL, and MBCs values from 0.19 to 1.75 mg/mL. The three tested essential oils and their main component (1,8-cineole) significantly increased the production of elastase and protease production, and motility in P. aeruginosa PAO1 in a dose dependent manner. In fact, at 10 mg/mL concentration, the three essential oils showed more than 50% of inhibition of elastolytic and proteolytic activities in P. aeruginosa PAO1. The same oils inhibited also the violacein production in C. violaceum strain. It was also noticed that at high concentrations, the A. corrorima essential oil significantly inhibited the germination of radish. A thorough knowledge of the biological and safety profiles of essential oils can produce applications of economic importance.

“…Due to lack of technological errors, the essential oil of the plant or bioactive compound of the particular cultivars (Seremna, Sawney, and Varlangy) has not been tested earlier. Several authors considered, the environmental conditions, e.g., type and composition of the soil (edaphic), geographic and genetic variations are the determinant factors influence the secondary metabolites of the essential oils [12][13][14]. Keeping the view in mind for cardamom pharmacological properties, we have studied the Seremna, Sawney, and Varlangy essential oils by gas chromatography-mass spectrometry (GC-MS) and also observed the effect of their essential oils for antifungal and antibacterial activities collected from Sikkim.…”

Objective: In Sikkim (India), Seremna is a highly growing cultivar of Amomum subulatum at lower altitudes. Other popular cultivated varieties are Varlangy and Sawney in the same state but at different altitude. In this study, we evaluate the variation in essential oils, metabolites and antimicrobial activities among A. subulatum selected cultivars. Methods: The composition of essential oil of Varlangy, Seremna, and Sawney was analyzed using gas chromatography–mass spectrometry and comparative antimicrobial activity of oils was explored using agar well diffusion and agar dilution method. Results: The Seremna cultivar oil was shown the high content of major constituents (1,8-cineole) in comparison to others. Comparative minimum inhibitory concentrations and minimal bactericidal concentration (MBC) or minimal fungicidal concentration against two Gram-positive (Staphylococcus aureus and Bacillus subtilis), two Gram-negative (Klebsiella pneumoniae and Escherichia coli) bacteria, and two (Candida albicans and Aspergillus niger) fungi were determined. The oil of Seremna showed distinct antibacterial and antifungal activity against all the microorganisms except B. subtilis which showed resistance. Conclusion: The present findings concluded that the high content of the principal compound accelerates the antimicrobial activity of essential oils. The essential oil of Seremna could be a good antimicrobial agent and recommended in the case of infections.
