Abstract

Curcuma amada Roxb. (Zingiberacae) is a highly valued rhizomatous perennial herb widely recognized for its culinary and medicinal properties. However, the anti-tyrosinase and anti-proliferative properties of C. amada leaf essential oil (CALEO) remain unexplored Therefore, the present study aimed to characterize the chemical composition and bioactivities of CALEO with an in silico analysis of its major constituents. A total of 46 compounds, accounting for 90.56% of the total oil, were identified by gas chromatography-mass spectrometry (GC-MS) analysis. CALEO was characterized by a high content of monoterpene hydrocarbons with camphor (13.48%) being the predominant constituent. CALEO showed significant antiproliferative activity against PC3, A375 and HepG2 cell lines with IC50 values of 26.67, 39.14 and 30.89 μg/mL, respectively. Additionally, CALEO exhibited potent tyrosinase inhibitory activity (IC50: 95.05 μg/mL) when compared to kojic acid (IC50: 82.84 μg/mL). Curdione, β-caryophyllene, germacrone and ar-turmerone showed strong binding affinities (< −5.5 kcal/mol) against mushroom tyrosinase, Bcl-2 and EGFR proteins. PASS prediction results highlighted the dermatological, antimetastatic and antineoplastic potential of spathulenol and β-caryophyllene. The cell-line cytotoxicity predictor (CLC) results predicted that all the major constituents have strong anticancer activity against various cancerous cell lines. The present results suggest that CALEO could be used as a biologically active natural product with promising antiproliferative and dermatoprotective effects. [ABSTRACT FROM AUTHOR]

Abstract

Piper nigrum (Black pepper), popularly called the "King of Spices" is one of nature's most ancient and miraculous traditional plants to treat several deadly maladies. The essential oil of P. nigrum is highly considered to have illustrious therapeutic significance in domestic and industrial applications. To validate the traditional claim of its essential oil's efficacy, the proposed study was designed to analyze the volatile profile and assess the antimicrobial and antiproliferative effect of P. nigrum fruit essential oil. This is the first study on the analysis of essential oil of P. nigrum collected from Eastern India. The Gas chromatography-mass spectrometry analysis of P. nigrum essential oil revealed β-caryophyllene (25.6%), limonene (15.7%), sabinene (11.6%), β-pinene (11.1%) and δ-carene (8.6%) as its major constituents. In antibacterial assays, P. nigrum essential exhibited significant activity against multiple microbial pathogens like Salmonella enterica serovar Typhi (ZOI-19±0.4 mm; MIC-0.781 μg/ml), Escherichia coli (ZOI-18±0.4 mm; MIC-1.562 μg/ml) and Staphylococcus saprophyticus (ZOI-18±0.4 mm; MIC-1.562μg/ml). MTT assay demonstrated selective cytotoxicity against cancerous cells such as HepG-2 (IC50-71.2±1.3 μg/ml); PC-3 (IC50-68.38±1.2 μg/ml) as compared to noncancerous 3T3L-1 cells (IC50- 235.77±1.6 μg/ml).To the best of our knowledge, this is the first-ever study from India on the cytotoxic potential of P. nigrum essential oil against the above two robust cancerous cell lines. The present findings revealed that P. nigrum essential oil exhibited remarkable therapeutic potential, which could enhance its medicinal worth and commercial significance in current scenario and in future perspectives for designing antimicrobial and anticancer drugs.

Abstract

Melaleuca polandii, commonly known as "Gold-tipped Bottlebrush", is widely grown in Indian gardens and parks as an ornamental plant. In the present study, the chemical composition, antioxidant, antimicrobial and cytotoxic activities of M. polandii leaf essential oil (MPLEO) have been investigated. GC-MS analysis of MPLEO isolated from plants grown along the coastal plains of Eastern India revealed the presence of 50 constituents with α-pinene (46.17%), 3Z-hexenyl acetate (10.10 %), α-terpineol (5.43%), limonene (3.63%) and ρ-cymene (2.44 %) as the major constituents. MPLEO exhibited moderate antioxidant capacity in DPPH, ABTS and Reducing ability assays with IC50 values of 7.94 ± 0.34 μg/mL, 5.71 ± 0.21 μg/mL and EC50 7.09 ± 0.35 μg/mL, respectively. Of the 5 bacterial strains tested, the EO exhibited highest sensitivity against Bacillus subtilis with the ZOI of 12.66 ± 0.57 mm and strong antimicrobial activity against Staphylococcus saprophyticus with MIC value of 6.25 μg/mL. MPLEO exhibited significant cytotoxic effects against Human alveolar lung adenocarcinoma (A549), Human hepato-cellular carcinoma (HepG2), Human cervix adenocarcinoma (HeLa) and normal Human Embryonic Kidney cell (HEK-293) as evaluated through MTT assay with IC50 values of 9.5 ± 0.38 μg/mL, 22.73 ± 0.95 μg/mL, 20.41 ± 0.82 μg/mL and 237.68 ± 9.26 μg/mL, respectively. The findings of the present study demonstrated that MPLEO could be considered as a potential bioresource having applications in pharmaceutical industries as an antibacterial and antiproliferative agent.
