Gene Expression Levels of Selected Factors in Monocytic Leukemia Cell Line THP-1 Upon Treatment with n-butanol Extract of Atractylis flava Desf against Cancer
Abstract:Objective: The aim of the present study was to screen the anticancer activity of Atractylis flava Desf in butanolic extract (AFBE). In addition, we attempted to investigate the gene expression levels of seven relevant genes involved in the pathways leading to toxicity: oxidative stress (NCF1, OPA1, SDHA), inflammation (TNFα), apoptotic balance (PDCD4, BCL2, CASP8) and the measurement of caspase-3 activity on the acute monocytic leukemia cell line THP-1. Material and Methods: The cell viability was assessed usi… Show more
“…Our previously reported data on A. flava verifies its anti-inflammatory, antipyretic, antioxidant, and anticancer potentials [6][7][8]. Some of the compounds present in the n-butanol extract of A. flava have already been confirmed to possess antidiabetic activities, for instance, the tiliroside and vicenin 3 [11].…”

“…(Asteraceae), locally called assenan aouragh in Algeria is one of the traditional medicinal plants which are widely distributed in the Mediterranean zone [5]. A.flava has shown significant antioxidant, anticancer, anti-inflammatory, and antipyretic activities [6][7][8]. Nonetheless, many health issues such as circulatory disorders, ulcers, intestinal parasites, and snakebite poisoning have been treated by a folk herbal drug made from Atractylis plants, while A. flava has also been reported to possess diuretic effects [9,10].…”
Background
Diabetes mellitus is a serious complex multifactorial disorder that imposes huge health and economic burden on societies. Because the currently available medications have many drawbacks, it's important to look for alternative therapies. Medicinal plants utilized in folk medicine are ideal candidates. Therefore, this work assessed the antidiabetic action of n-butanol extract from the whole plant Atractylis flava Desf (BEAF). These ethnomedicinal properties of BEAF were scientifically validated using in vitro and in vivo assays. In vitro antidiabetic effect of the BEAF was conducted using α-Glucosidase and α-Amylase assays. While the antihyperglycemic activity was assessed using two rat models: Alloxan-induced diabetic rats and oral glucose challenged rats. Experimental diabetes was induced by a single intraperitoneal injection of alloxan at a dose of 150 mg/kg and animals with fasting blood glucose levels (BGL) > 200 mg/dL were considered diabetic. Glibenclamide (5 mg/kg) was used as a typical drug.
Results
The BEAF at all tested dose levels (100, 250, and 500 mg/kg) showed a significant decrease in blood glucose level in all the two animal models. Besides, the plant extract exhibited a potent inhibitory effect on α-Amylase and α-Glucosidase activity at a concentration of 1000 µg/mL with 76.17% and 89.37%, respectively.
Conclusion
BEAF exerts in vitro and in vivo antidiabetic effects, these results suggest that the plant extract can be a therapeutic resource in the treatment of diabetes and hyperlipidemia.

The study has the intent of exploring the dynamics of biologically active substance (BAS) extractions from red raspberry (R. idaeus) shoots in order to determine the appropriate extraction frequency. A secondary objective is to assess the relationship between extract antioxidant activity and BAS content.
The focus of the study revolved around R. idaeus shoots, and the spectrophotometric method of analysis was applied to determine the amount of the catechins, polyphenols, hydroxycinnamic acids derivatives and flavonoids, while the gravimetric method was used to determine the dry residue of the extracts and the potentiometric method applied for evaluating antioxidant activity.
The polyphenols amount was 1.74±0.03, 0.58±0.01 and 0.016±0.005%, catechins – 1.50±0.02, 0.50±0.01 and 0.11±0.01%, flavonoids – 0.08±0.005, 0.046±0.005 and 0.016±0.002%, hydroxycinnamic acids derivatives – 0.24±0.005, 0.078±0.005 and 0.017±0.002%, organic acids – 0.15±0.005, 0.05±0.005 and 0.01±0.002, dry residue – 2.14±0.005, 0.72±0.01 and 0.16±0.005%, antioxidant activity – 94.80±1.90, 47.40±0.95 and 7.90±0.16 mM-eqv./m for the 1st, 2nd and 3rd extraction, respectively. The optimal extraction frequency of raspberry shoots with distilled water was two times. The highest value of Peasorn‘s correlation coefficient was between the antioxidant activity and catechins (r = 0.9813) and the lowest in the case of organic acids (r=0.9112).
The appropriate extraction frequency of R. idaeus shoots with distilled water was two times. The antioxidant method of determination extraction frequency was not inferior to the traditional method. The catechins dominated in the extracts from R. idaeus shoots. A significant positive correlation was content of catechins and antioxidant activity.
Phytochemical compounds are known to be components of many plants and herbs; they have received great interest from the public and scientists due to their health benefits as antioxidants. The aim of the present study was to reveal the bioactive compounds and evaluation of antioxidant activity of the dichloromethane, ethyl acetate, n-butanol and residual water extracts of Atractylis aristata. The bioactive compounds analysis was investigated using HPLC-UV analysis obtained at 254nm and optimized with 16 standards, ABTS and DPPH methods were used for estimating the antioxidant capacity. Thirteen bioactive compounds were identified in the extracts by comparing the retention time. Major compounds detected in the extracts were Acetylsalicylic acid, Ascorbic acid, Gallic acid, Quercetin and Vanillin. All extracts give an antioxidant capacity varied with polarity of solvents. The residual water extract demonstrated a significant amount of total phenolics, flavonoids and condensed tannins (3.544±0.738mg of GAE/g DW, 3.104±0.6760mg of QE/g DW and 2.692±0.561mg of CE/g DW, respectively). In two methods tested to evaluate the antioxidant activity, ethyl acetate extract displayed the highest antioxidant capacity (IC50 value: 0.097±0.003mg/ml in DPPH assay and IC50 value: 0.077±0.003mg/ml in ABTS assay).
