“…There are 200 species of Zingiberaceae belonging to 20 genera found in Thailand. In recent years, several reports have been published concerning the composition and/or the biological properties (antimicrobial, antioxidant, anticancer and a stimulated effect on the immune system) of Zingiberaceae extracts [10][11][12][13][14][15][16]. These studies have emphasized the existence of marked chemical differences among oils extracted from different species or varieties.…”

Essential oil obtained by hydrodistillation and two different solvent extractions (petroleum ether and ethanol) from five Zingiberaceae species: ginger (Zingiber officinale Roscoe.), galanga (Alpinia galanga Sw.), turmeric (Curcuma longa L.), kaempferia (Boesenbergia pandurata Holtt.) and bastard cardamom (Amomum xanthioides Wall.) was characterized. Volatile components of all extracts were analyzed by gas chromatographymass spectrometry (GC-MS). The major components of ginger, turmeric, galangal, bastard cardamom and kaempferia were zingiberene, turmerone, methyl chavicol, and γ-terpinene, respectively. Their antibacterial effects towards Escherichia coli, Staphylococcus aureus, Bacillus cereus and Listeria monocytogenes were tested by a disc diffusion assay. Essential oil of kaempferia and bastard cardamom obtained by hydrodistillation extraction could inhibit growth of all tested bacteria. Essential oil of ginger extracted by hydrodistillation had the highest efficiency against three positive strains of bacteria (S. aureus, B. cereus and L. monocytogenes), with a minimum concentration to inhibit B. cereus and L. monocytogenes of 6.25 mg/mL.

Abstract:In the present study, solvent extracts from aerial parts of Anacyclus pyrethrum L. were assessed for their total phenol content, antimicrobial and antioxidant (1,1-diphenyl-2-picrylhydrazyl free radical scavenging and ferric-ion reducing power) activities. The amounts of total phenolics and flavonoids in the solvent extracts were determined spectrometrically. (310.78 mg GA/g extract) and antioxidant activity (IC 50 = 0.056 mg/mL).Increasing the concentration of the extracts resulted in increased ferric reducing antioxidant power for both extracts tested.The methanolic extract exhibited the best antimicrobial activity against three gram-positive bacterium (Listeria monocytogenes: 100%, Bacillus. cereus: 69% and Staphylococcus aureus: 66%), as well as against Candida albicans (81%).Finally, a relationship was observed between the biological activities potential and total phenolic and flavonoid levels of the extract. The results of this study provided an alternative of utilising Anacyclus pyrethrum aerial parts as readily accessible source of natural antioxidant in food cosmetic and pharmaceutical industry.

“…9. In the same purpose [23], tested hot water polysaccharide extracts of A. pyrethrum for their immunostimulating activity in vitro and in vivo, and they showed a markedly enhancing of the proliferation of the murine spleen cells in vitro. The results of the in vivo study at a dose of 50 mg/kg also showed that A. pyrethrum has better effects than obtained with the in vitro study at 50 µg/mL.…”

Objective: The objective of this study is to evaluate the chemical contents (total phenolic and total flavonoid contents) of the crude ethanolic and aqueous extracts from leaves and stems of a Lebanese plant and to evaluate their cytotoxic and antioxidant activities.Methods: Quantification of the total phenolic and total flavonoid contents of all extracts of Anacyclus nigellifolius from leaves and stems and the cytotoxic activity were evaluated through XTT assay, while antioxidant activities were evaluated using spectrophotometric analyses DPPH, H 2 O 2 , and chelating of ferrous ions tests. Results:The ethanolic extract from leaves and stem of A. nigellifolius was better than aqueous extract and showed a higher content in total phenolic and total flavonoid which was 39.48±0.04 and 13±0.03, respectively. On the other hand, the best value of IC50 of DPPH, H 2 O 2 , and chelating of ferrous ions of ethanol extract from leaves was 0.1 mg/mL, 0.25 mg/mL, and 0.37 mg/mL, respectively, also, ethanol extract has significantly inhibited cells growth 293T and MCF7, a percentage of inhibition was in leaves, and it has reached the 70% and 54%, respectively. Conclusions:Both ethanolic and aqueous extracts of both parts of A. nigellifolius have shown high efficiency and good antioxidant and antiproliferation power. Hence, this plant can be used in the prevention of a number of diseases related to oxidative stress as well as might be used for inhibition of cancer cell line growth.
