Acacia saligna and Lawsonia inermis natural populations growing in Northern Saudi Arabia might be a valuable source of polyphenols with potent biological activities. Using high-performance liquid chromatography–diode array detection (HPLC-DAD), several polyphenols were detected tentatively in considerable amounts in the methanolic leaf extracts of A. saligna and L. inermis. A. saligna mainly contained rutoside, hyperoside, quercetin 3-glucuronide, gallic acid and p-coumaric acid, whereas those of L. inermis contained apigenin 5-glucoside, apigetrin and gallic acid. Strong antioxidant activities were found in the leaf extracts of both species due to the presence of hyperoside, quercetin 3-glucuronide, gallic acid, isoquercetin, p-coumaric acid, quercitrin and rutoside. A. saligna and L. inermis leaf extracts as well as hyperoside, apigenin 5-glucoside, and quercetin 3-glucuronide significantly reduced reactive oxygen species accumulation in all investigated cancer cells compared to the control. Methanolic leaf extracts and identified polyphenols showed antiproliferative and cytotoxic activities against cancer cells, which may be attributed to necrotic cell accumulation during apoptotic periods. Antibacterial activities were also found in both species leaf extracts and were twice as high in A. saligna than L. inermis due to the high composition of rutoside and other polyphenols. Finally, strong antifungal activities were detected, which were associated with specific phenols such as rutoside, hyperoside, apigenin 5-glucoside and p-coumaric acid. This is the first study exploring the polyphenolic composition of A. saligna and L. inermis natural populations in northern Saudi Arabia and aiming at the detection of their biological activities.

“…coli [ 45 ]. The phytochemical compounds of henna have antibacterial and antioxidant activity [ 46 ], while the methanolic extract of Lawsonia inermis has been found to be effective against nymphs and adults of the cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) [ 47 ]. The insecticidal activity of fruit and leaves of Lawsonia inermis has also been estimated against the major pest of stored grains, the red flour beetle, Tribolium castaneum (Herbst) [ 48 ].…”

Researchers are increasingly looking to plants as sources of novel ingredients active against vector-borne diseases. Medicinal plant extracts and their metabolites are an attractive source for such products. This study investigated the insecticidal activity of five essential oils extracted from the most common medicinal herbs in Jazan province, Kingdom of Saudi Arabia. Extracted oils and nanoemulsions synthesized from those oils were characterized before application at different concentrations to laboratory-reared fourth-stage larvae of Culex pipens. Basil (Ocimum bascilicum) and cumin (Cuminum cyminum) essential oils showed moderate larvicidal effect with LC50 81.07 ug/mL and 96.29 ug/mL, respectively. That activity was improved in their nanoemulsion forms, as evidenced by a reduction in the LC50 to 65.19 ug/mL for basil and 64.50 ug/mL for cumin. Clove (Syzygium aromaticum), henna (Lawsonia inermis) and ginger (Zingiber officinalis) oils showed weaker insecticidal activity, with LC50 values of 394 ug/mL, 306 ug/mL, and 494 ug/mL, respectively. Moreover, the nanoemulsion forms of those essential oils did not show any improvement in their insecticidal activity. In conclusion, of the studied plants, the nanoemulsions of basil and cumin showed significant larvicidal activity.

“…These covalent bonds enhance the strength of fibers in the fabrics [23]. Apart from that henna dye have higher affinity towards cotton fabrics because it has hydroxyl group and bonded by covalent bond [24]. Moreover the abrasion results was good for henna coated fabrics due to happens of Lawsone which are functional groups of henna dye.…”

This study is presents the preparation and characterization on natural dyes based on neem, henna and turmeric for dyeing on cotton with superhydrophobic coating. Natural dyes were used to reduce the usage of the synthetic dyes in dyeing process and superhydrophobic coating to maintain the colour of the dyes on the fabric from faded and acts as a self-cleaning. The methodology involved for this study was the extraction process of natural dyes from the neem, henna and turmeric. There are eight different concentrations consists of 0.25g/ml, 0.5g/ml, 0.75g/ml, 1.0g/ml, 1.25g/ml, 1.50g/ml, 1.75g/ml and 2.0g/ml. The mechanical test involved is abrasion test for evaluation the resists wear caused by flat rubbing contact with another materials. Henna coated co tton fabrics have lower percentage weight loss compared to neem and turmeric coated cotton fabrics and uncoated cotton fabrics. The weight percentage loss for henna coated cotton fabrics at 2.0g/ml was 3.32%, for neem coated cotton fabrics at 2.0g/ml was 3.33% and turmeric at 2.0g/ml concentration was 3.34%. On the other hand, the value for the henna uncoated cotton fabric at 2.0g/ml was at 3.41%, neem at 2.0g/ml concentration was 3.42% and the value for uncoated turmeric at 2.0g/ml was 3.43% respectively. The porosity decreases when the concentration of dyes and superhydrophobic coating applied on the cotton fabrics.
