Gostin IN, Blidar CF. Glandular Trichomes and Essential Oils Variability in Species of the Genus Phlomis L.: A Review. PLANTS (BASEL, SWITZERLAND) 2024; 13:1338. [PMID: 38794409 PMCID: PMC11125434 DOI: 10.3390/plants13101338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 05/09/2024] [Accepted: 05/09/2024] [Indexed: 05/26/2024]
Abstract
The genus Phlomis is one of the largest genera in the Lamiaceae family and includes species used since ancient times in traditional medicine, as flavoring for food and as fragrance in cosmetics. The secretory structures (represented by glandular trichomes) as well as the essential oils produced by them constitute the subject of this review. While representatives of this genus are not typically regarded as large producers of essential oils compared to other species of the Lamiaceae family, the components identified in their essential oils and their biological properties necessitate more investigation of this genus. A comprehensive analysis of the specialized literature was conducted for each of the 93 currently accepted species to identify all the results obtained by researchers regarding the secretory structures and essential oils of this genus up to the present time. Glandular trichomes, still insufficiently studied, present morphological peculiarities that differentiate this genus within the family: they are of two categories: capitate (with a wide distribution in this genus) and dendroid. The peltate trichomes, characteristic of many species of this family, are absent. The essential oils from the species of the genus Phlomis have been much more widely studied than the secretory structures. They show considerable variability depending on the species and the environmental conditions.

Assessing the Chemical Composition, Antioxidant and enzyme Inhibitory Effects of Pentapleura subulifera and Cyclotrichium glabrescens Extracts. Chem Biodivers 2024; 21:e202301651. [PMID: 38016080 DOI: 10.1002/cbdv.202301651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 11/28/2023] [Accepted: 11/28/2023] [Indexed: 11/30/2023]
Abstract
The Lamiaceae family, encompassing diverse plant species, holds significant value in food, medicine, and cosmetics. Within this family, Pentapleura subulifera and Cyclotrichium glabrescens, relatively unexplored species, were investigated for their chemical composition, antioxidant capacity, and enzyme-inhibiting effects. The chemical composition of hexane, methanolic, and aqueous extracts from P. subulifera and C. glabrescens were analyzed using LC-ESI-MS/MS and the non-polar hexane fraction was investigated via GC-MS. The antioxidant potential of the extracts was determined through radical scavenging, reducing power and metal chelating assays. Additionally, inhibitory activity against six enzymes - acetylcholinesterase (AChE), butyrylcholinesterase (BChE), tyrosinase, amylase, and glucosidase - was examined. The aqueous extract of P. subulifera and the methanolic extract of C. glabrescens exhibited elevated phenolic content at 129.47 mg gallic acid equivalent (GAE)/g and 55.97 mg GAE/g, respectively. Chemical profiling of the constituents of the two plant species resulted in the identification of a total of twenty compounds. The majority of which belonged to flavonoids and quinic acid derivatives, primarily concentrated in the methanol and aqueous extracts. Among all antioxidant assays, the aqueous extracts of P. subulifera demonstrated superior antioxidant activity, with the highest recorded activity of 404.93 mg trolox equivalent (TE)/g in the cupric reducing antioxidant capacity (CUPRAC) test. Meanwhile, the hexane extract of C. glabrescens exhibited the highest AChE inhibitory activity at 2.71 mg galanthamine equivalent (GALAE)/g, followed by the methanol extract of P. subulifera at 2.41 mg GALAE/g. These findings unequivocally establish the notable antioxidant and enzyme inhibitory activity of P. subulifera and C. glabrescens extracts, underscoring their potential as a source of valuable natural antioxidants.

Phytochemical Profiling by UPLC-ESI-QTOF-MS of Kalaharia uncinata (Schinz) Moldenke, Widely Used in Traditional Medicine in DR Congo. Chem Biodivers 2023; 20:e202300826. [PMID: 37593932 DOI: 10.1002/cbdv.202300826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 08/16/2023] [Accepted: 08/17/2023] [Indexed: 08/19/2023]
Abstract
Kalaharia uncinata (Schinz) Moldenke, is a tropical erect bushy shrub or subshrub of the Lamiaceae family. It is an endemic plant species of Southern Africa, widely used in the pharmacopoeia against upper respiratory tract infections. A previously conducted ethnobotanical survey revealed that it is believed to contain bioactive substances. However, no relevant phytochemical information was available. This study aimed to perform a phytochemical characterization of K. uncinata and also to discuss the potential bioactivity of the identified phytochemical constituents based on documented data. Ultra-performance liquid chromatography with electrospray ionization quadrupole time-of-flight mass spectrometry (UPLC-ESI-QTOF-MS) was used for profiling and identification of the main phytochemical constituents from leaf extracts (MeOH 90 %, DCM, AcOEt, BuOH, hexane and residue) of K.uncinata. Twenty-four constituents, representing mainly flavonoids (14), followed by phenylethanoid glycosides (7), phenolic acids (2), and an iridoid glycoside (1) were tentatively identified. Most of the identified compounds are documented to have antiviral and anti-inflammatory properties, which could possibly be the rationale behind the use of K. uncinata against upper respiratory tract infections.

Evaluating the effects of zeolitic imidazolate framework and Eremostachys binalodensis extract on Candida albicans and Streptococcus mutans biofilms. Eur J Oral Sci 2022; 130:e12904. [PMID: 36372561 DOI: 10.1111/eos.12904] [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: 04/14/2022] [Accepted: 10/21/2022] [Indexed: 11/15/2022]
Abstract
Biofilms represent longstanding challenges to oral health care. Candida albicans and Streptococcus mutans are the common pathogens forming biofilms. The growing resistance to and the adverse effects of antibiotics limit their usage and raise the need for novel approaches. Herbal extracts have emerged as efficient choices with lower costs and fewer adverse effects. Metal frameworks have captivated interest due to their high surface area, special biocompatibility, and non-toxicity. The effects of zeolitic imidazolate frameworks/layered double hydroxide (ZIF/LDH) on fungal infections and the potential effects of Eremostachys binalodensis on bacteria encouraged the researchers to evaluate the effect of ZIF/LDH, E. binalodensis, and their combination on C. albicans and S. mutans biofilms. ZIF/LDH nanocomposite was synthesized and characterized using scanning electron microscopy, Fourier transform infrared spectra, and X-ray diffraction to assess morphology and chemical structure. Methanol extracts of the areal parts of E. binalodensis were obtained by Soxhlet extraction. The microdilution tests and biofilm crystal violet staining were applied. Concentrations of 2.048 and 4.096 mg/ml E. binalodensis prevented C. albicans and S. mutans biofilm formation. The combination of ZIF/LDH + E. binalodensis prevented C. albicans and S. mutans biofilm formation. This research suggests the use of E. binalodensis-loaded ZIF/LDH nanocomposites for removing biofilms.
