Metabolic Behavior

The native Chilean shrubs Buddleja globosa (Matico) and Ribes magellanicum (Zarzaparrilla) are used widely at a rural level, due to their medicinal properties. Nevertheless, little is known about their secondary metabolites and cytotoxic effect. The aim of this study was to evaluate the content of different compounds like catechin, epicatechin, p-coumaric acid and the antioxidant capacity by ABTS, ORAC, FRAP and DPPH methods. In addition, the cytotoxic activity of both extracts was evaluated against Chinese hamster ovary (CHO-K1) cell lines by MTT and neutral red assays. The results suggest that the most abundant constituent in Budleja globosa and Ribes magellanicum were catechin (682.43 mg/100 g DW) and epicatechin (3362.08 mg/100 g DW) respectively; while the ORAC methodology showed an elevated antioxidant activity for Matico (134147.31 μmol Trolox Eq/100 g DW). On the other hand, both extracts at the assayed concentrations affect the membrane stability and cellular metabolic capacity of the CHO-K1 cell lines. These finding provide a direction for further researches, and suggest the Matico and Zarzaparrilla flower extracts as promising sources of antioxidants, and as research objects through the analyze of their metabolic behavior and antitumoral potential.

BALB/C 3T3 mouse fibroblasts or CHO cells grown in 96-well microtitre plates were used for the neutral red viability assay. The cytotoxicity and ability of microsomes or an S9 mixed function oxygenase to activate cyclophosphamide were compared. A pronounced cytotoxic effect of both activation systems was found using CHO cells, but not using 3T3 cells. 3T3 cells were more sensitive than CHO cells to the active metabolites of cyclophosphamide. Cyclophosphamide was more efficiently converted to toxic metabolites by microsomes than by the S9 mix. A concentration of microsomes corresponding to 0.032mg protein per ml of medium was shown to be optimal for the activation of cyclophosphamide in both cell lines.

Cloves (Syzygium aromaticum) as been used as traditional medicine for many years and they possess antibacterial, antifungal and antiviral properties. Clove is known for its anticancer property on various cancer cell lines and is well established, but its anticancer effect on OSCC cell lines is less known.  Aim of the study was to determine the anticancer and antioxidant effect of Syzygium aromaticum extract on OSCC cell lines (KB cell lines) and compare the same with normal mouse fibroblasts cell lines (L292 cell lines). KB cell lines and L292 cell lines were commercially obtained.  Clove was obtained from local market and ethanolic extract (EC) of clove was prepared. Anticancer activity was assessed by MTT, neutral red, DAPI and Double staining assay and antioxidant assay was carried out by FRAP, PM and DPPH assay. The antioxidant property of EC of clove increased with increase in the concentration in a dose dependent manner. Both MTT and Neutral Red assay showed increase in cell death with increase in concentration of EC of clove. Double staining and DAPI showed increase in cell death when treated with EC of clove. The anticancer and antioxidant activity of EC of clove was comparable with standard drug used in the assay. This in vitro study demonstrates effective anticancer and antioxidant activity on KB cell lines when compared to standard control. However, further studies are to be conducted in order to characterize other potential antitumor components of the clove, so that it can be used as therapeutic agent in treating oral carcinoma.

The article is devoted to the creation of a carbohydrate product with rosehip extract in the form of sweets (glucose Fudge) with a therapeutic and preventive effect aimed at restoring the body of people exposed to intense physical and mental stress and the effects of damaging environmental factors. As carbohydrates in the recipe, simple carbohydrates (glucose) and complex carbohydrates in the form of starch molasses containing (maltose, tri - Tetra - sugars, dextrins) are used. Glucose in the formulation is the main energy ingredient, sweetener and structure-forming component that gives the product a solid consistency due to crystallization. The medicinal effect of the product is provided by rosehip extract. Numerous published studies have established its vitamin, immunostimulating and antioxidant activity, inhibition of uric acid formation and obesity, which are associated with flavonoids, other phenolic compounds, and vitamins. The list of medicinal properties of rosehip extract shows the feasibility of using it in additional nutrition of people in order to prevent diseases. For the formulation of our sweets, the extraction of crushed rosehip fruits was carried out three times with hot water at a temperature of 65-700C, followed by concentration of the extract under vacuum to 25-30% SV. The resulting extract-concentrate was introduced into the formulation in a dosage of 5.5% SV per 100 g of SV glucose Fudge, which provided the necessary dosage for the product when used from 3 (for children) to 10 sweets a day (for adults) for the prevention of colds.

Background: P. mucronata (Pm) comes from South America, Brazil and is characterized as “Maracujá de Restinga”. It is used in folk medicine for its soothing properties and in treating insomnia. Objective: The present study for the first time analyzed the antioxidant and cytotoxicity of the hydroalcoholic leaves extract and fractions from Pm. Method: The cytotoxicity test will be evaluated by different assays (MTT and CV) against human prostate cancer (PC3) and mouse malignant melanoma (B16F10) cell lines, and the antioxidant test by DPPH method. Results: β-Amyrin, oleanolic acid, β-sitosterol and stigmasterol were isolated of the most active, hexane fraction. These substances were tested against the tumor cell lines: β-sitosterol and stigmasterol showed the most relevant activity to PC3 in CV assay and, oleanolic acid to B16F10 by the MTT assay. In addition, it was possible to indicate that the mode of cell death for stigmasterol, presumably is apoptosis. In terms of antioxidant activity, the hydroalcoholic leaves extract presented higher activity (EC50 133.3 µg/mL) compared to the flower (EC50 152.3 µg/mL) and fruit (EC50 207.9 µg/mL) extracts. By the HPLC-MS, it was possible to identify the presence of flavones in the leaf extract (isoschaftoside, schaftoside, isovitexin, vitexin, isoorientin, orientin). Conclusions: P. mucronata hexane fraction showed promising cytotoxic effect against cancer cell lines, and stigmasterol contributes to this activity, inducing apoptosis of these cells. Furthermore, as other Passiflora species, Pm extract showed antioxidant activity and flavones are its major phenolic compounds.
