Abstract
Two pimaranes ent-pimara-8(14),15-dien-19-oic acid (1: ) and ent-8(14),15-pimaradien-3β-ol (2: ), isolated from Aldama arenaria, and six semi-synthetic derivatives methyl ester of the ent-pimara-8(14),15-dien-19-oic acid (3: ), ent-pimara-8(14),15-dien-19-ol (4: ), acetate of ent-pimara-8(14),15-dien-19-ol (5: ), ent-pimara-8(14),15-dien-19-ol succinic acid (6: ), acetate of ent-8(14),15-pimaradien-3β-ol (7: ), ent-8(14),15-pimaradien-3β-ol succinic acid (8: ) were evaluated in vitro for their cytotoxic activities to childhood leukemia cell lines and leishmanicidal activity against the parasite Leishmania amazonensis. Among these compounds, 1: to 6: presented moderate cytotoxic activity, with compound 4: being the most active (GI50 of 2.6 µM for the HL60 line) and the derivatives 7: and 8: being inactive. Against the parasite Leishmania amazonensis, the most promising derivative was the acetate of ent-pimara-8(14),15-dien-19-ol (5: ), with EC50 of 20.1 µM, selectivity index of 14.5, and significant reduction in the parasite load. Pimarane analogues 1: , ent-pimara-8(14),15-dien-19-oic acid, and 2: , ent-8(14),15-pimaradien-3β-ol, presented different activities, corroborating the application of such molecules as prototypes for the design of other derivatives that have greater cytotoxic or leishmanicidal potential.

Influence of seasonal variation on the chemical composition and biological activities of essential oil from Eugenia pohliana DC leaves. Chem Biodivers 2022; 19:e202200034. [PMID: 35864035 DOI: 10.1002/cbdv.202200034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 07/20/2022] [Indexed: 11/07/2022]
Abstract
The purpose of this study was to analyse the influence of seasonal variation on the chemical composition and antimicrobial, antioxidant and cytotoxicity activities of the essential oil (EO) extracted from the leaves of Eugenia pohliana. Chemical characterisation of the samples- by gas chromatography-mass spectrometry- found 35 and 38 components for summer and winter, respectively, of the EO from E. pohliana leaves, totaling 47 different compounds. Analysis of antioxidant capacity (DPPH, ABTS and TAC) revealed that the summer EO showed greater free radical scavenging capacity than the winter. Similarly, the summer EO exhibited superior antimicrobial potential (MIC=128-512 μg/mL and MMC=128-1024 μg/mL, compared to the winter EO (128-2048 μg/mL and 256-2048 μg/mL, respectively). Results showed that both oils had a low potential to cause haemolysis. This study provides new scientific evidence on the influence of seasonality on the pharmacological properties of E. pohliana leaves and its potential for the development of herbal medicines.

Rathore S, Mukhia S, Kapoor S, Bhatt V, Kumar R, Kumar R. Seasonal variability in essential oil composition and biological activity of Rosmarinus officinalis L. accessions in the western Himalaya. Sci Rep 2022; 12:3305. [PMID: 35228638 PMCID: PMC8885650 DOI: 10.1038/s41598-022-07298-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 02/10/2022] [Indexed: 01/22/2023] Open
Abstract
Rosmarinus officinalis L. is an imperative herb used in pharmaceutical yet knowledge on chemical and activity profile of essential oil (EO) to harvest seasons and accessions from the Himalayan region is limited. Thus, accessions were evaluated to determine the EO content, compositional, antimicrobial, and cytotoxic potential of rosemary in different harvest seasons during 2018‒2019. EO content was 30.5% higher in IHBT/RMAc-1 compared with IHBT/RMAc-2 accession while 27.9% and 41.6% higher in the autumn as compared with summer and rainy season, respectively. Major EO compound was 1,8-cineole; ranged from 32.50‒51.79% during harvest seasons and 38.70‒42.20% in accessions. EO was active against both the tested Gram-positive bacteria (Micrococcus luteus MTCC 2470 and Staphylococcus aureus MTCC 96). EOs showed inhibition of Gram-negative bacteria (Salmonella typhi MTCC 733), while Klebsiella pneumoniae MTCC 109 was found to be resistant. The rosemary EO of T1 (Rainy season IHBT/RMAc-1) was most effective against S. aureus MTCC 96 with the minimum inhibitory concentration (MIC) of 4% (v/v). In vitro cytotoxicity evaluation showed no potential anti-proliferative activity of EO. The rosemary EO profile in the western Himalayan region was influenced by harvesting seasons and genetic variability within the accessions; furthermore, a promising antibacterial agent in pharmaceutical and flavour industries.
