The present study was conducted to investigate the color strength (K/S), colorfastness, antibacterial and antioxidant properties of silk using fabric Cichorium intybus root extract as a natural dye. Comparative results of color fastness (fastness to wash, rub, light and perspiration) and colorimetric properties (CIELab and K/S values) of dyed silk samples were studied to quantify the effect of mordants and mordanting method. Alum and myrobalan were used as mordants. Three methods of mordanting techniques were used (pre, meta and post-mordanting). The samples showed acceptable color strength and colorfastness values. The antibacterial activity of the dyed samples with and without mordants was tested against common pathogens Escherichia coli and Staphylococcus aureus. The antioxidant property of the dyed fabric was analyzed by DPPH method. Cichorium intybus proved to be very effective in inhibiting microbial growth. The results of DPPH assay were positive for all the samples. The dyeing of silk fabric with Cichorium intybus root extract provided a multifunctional textile material with both antioxidant and antibacterial...

Tunisian flora contains several wild plants with diverse therapeutic uses. As a contribution to the efforts to select natural sources of antitumor compounds, we investigated in this study the antiproliferative activity of several extracts of the Tunisian species: Astragalus gombo, Nicotiana glauca and Artemisia campestris. Dried aerial part (A. gombo and A. campestris) and leaves (N. glauca) were extracted with ethyl acetate, dichloromethane, and methanol. In the vitro anti-proliferative activity of the extracts was tested against the human solid tumor cell lines: HBL-100, T-47D, and WiDr. Tests were performed using the sulforhodamine B (SRB) assay. All extracts of A. campestris and A. gombo were active against all tested cell lines, with GI50 values between 12 and 93 µg/ml. Dichloromethane extract of A. campestris was the most active extract with GI50 of 12 µg/ml against HBL-100 cell line. This kind of cell seems to be the most sensitive regarding all tested extracts. Our results showed that A. gombo, A. campestris and N. glauca are a promising source of natural antitumor...

Teucrium polium L. is a member of the Lamiaceae family and is represented in the Flora of Syria by two variety: Teucrium polium var. angustifolium and Teucrium polium var. mollissimum. Teucrium polium is a wild-growing flowering plant, found abundantly in Syria, and it is used traditional medicine for it’s diuretic, antipyretic, antispasmodic, tonic, anti-inflammatory, antihypertensive, anorexic, analgesic, antibacterial and anti-diabetic effects. Several reports have demonstrated a wide range of beneficial biological and pharmacological activities of the phenylethanoid, phenylpropanoid and flavonoid components, while the furano neo-clerodane diterpenoids present in germander have been implicated in the in–vivo hepatotoxicity of this botanical. Phytochemical studies of this plant have been carried out. Aerial parts of the plant were extracted with petroleum ether at room temperature, and then extract with methanol in Soxhlet, and finally extract with aqueous methanol at room temperature successively. Fractionation of the methanol extract by column chromatography and purification by crystallization yielded three known flavonoids cirsimartin, cirsiliol, and apigenin. The aqueous methanolic extract yielded one new neo-clerodane type diterpenoid, syrapolin...

The traditional Indian medicine – Ayurveda, describes various herbs, fats, oils and minerals with anti-aging as well as wound healing properties. Wounds are the result of injuries to the skin that disrupt the soft tissue. Wound healing can be defined as a complex dynamic process results in the restoration of anatomic continuity and function. Various plant products have been used in the treatment of wounds over the years. Wound healing herbal extracts promote blood clotting, fight infection, and accelerate the healing of wounds. Hence in the current review, a list of the plants used in traditional medicine for the treatment of wounds was screened. It is a beneficial work for researchers to provide many details about the wound healing herbs and development of safe and effective and globally accepted herbal drugs for cuts and...
