The aim of present study was to assess phytochemical profile and antibacterial activities of some selected bacterial species. All the bacteria species tested showed higher inhibition zone varying from 20mm-27mm with 100mg/ml of ethyl acetate, methanol, Hexane and chloroform respectively. Moreover, the phytochemical profile revealed the presence of steroids, alkaloids, flavonoids and tannin in the extracts. Thus, result of this study showed that Garlic bulb extract could be a good candidate for production of synthetic antibacterial drug for the treatment of infections caused by the organisms used in this study.

Background Conyza blinii H. Lév is a medicinal plant that has a variety of pharmacological activities, but its study is at a standstill due to the shortage of resources. Method This study utilized the surface sterilization method to isolate endophytic fungi, and they were preliminarily identified by morphology. Flavonoid-producing strains were screened by NaNO2-Al(NO)3 colorimetry and further identified by the ITS sequence. Additionally, we used five antioxidant assays (DPPH, Hydroxyl radical, ABTS, FRAP and T-AOC assays) to systematically evaluate the antioxidant capacity of total flavonoids , and we also determined their antibacterial activity. Results In this study, 21 endophytic fungi were isolated from wild Conyza blinii H. Lév for the first time. There were six flavonoid-producing strains, especially CBL11, whose total flavonoid content reached 50.78 ± 2.4 mg/L. CBL12, CBL12-2 and CBL1-1 all exhibited excellent antioxidant activity. The effect of CBL12 was similar to that of ascorbic acid at low concentrations, and its radical scavenging rates for DPPH and ABTS were 94.56 ± 0.29 % and 99.88 ± 0.27%, respectively, while its IC50 values were only 0.11 ± 0.01 mg/mL and 0.2 ± 0.01 mg/mL. Through LC-MS, we found that CBL12 could produce many high-value flavonoids, such as 3-methoxyflavone, nobiletin, formononetin, scopoletin, and daidzein. Additionally, CBL9 had good antibacterial activity against both gram-positive and gram-negative bacteria. Notably, we obtained the high-yield strains CBL12 and CBL9, which not only had high yields (10.64 ± 1.01 mg/L and 10.17 ± 0.11 mg/L, respectively) but also had excellent biological activity. Hence, the results of this study provide new ideas for endophytic fungi that can be exploited as a source of flavonoids and other medicinal components from Conyza blinii H. Lév. Moreover, this study can serve as a reference for the development of rare medicinal materials.

ABSTRACT The desert plant, Calortopis procera, known also as the apple of Sodom, is an important but less known medicinal plant. This plant has many ethnic medicinal uses especially for skin-related symptoms in the countries of its origin: India, Africa, Saudi, Yemen, Lebanon, Israel, Jordan, Sudan, Iran, and Afghanistan. The plant is also known and used in traditional medicine in South and tropical America, due to its introduction and cultivation in that part of the world. Skin problems treated by the plant include: wounds, scabies, sores, external infections, swellings, rheumatic pains, leprosy, toothaches, eczema and even the treatment of paralyzed limbs. Other traditional uses include: asthma, cough, diarrhea, malaria, cancer, dysentery jaundice and many more. An insight into the scientific activity of C. procera derived extracts and compounds suggest that these extracts have antidiabetic, anticancer, anti-inflammatory and antibacterial activities. Moreover, a compound with high activity against cancer cell was developed from cardenolides present in C. procera root bark, presenting a significant prospect in the use of this plant for modern medicine. The purpose of this communication is to review the full extent of the ethnobotanical uses of the apple of Sodom, and to shed a light on this high-potential lesser-known desert medicinal plant.

Secondary metabolites, DIBOA, HBOA, 7-OH-HBOA, BOA and gallic acid, were isolated and quantified from Calceolaria thyrsiflora Graham, a native medicinal plant of Chile belonging to the Scrophulariaceae family. The highest DIBOA contents were determined in leaves (145 mmol kg-1 dry wt) and flowers (161 mmol kg-1 dry wt). Antibacterial activities of DIBOA, HBOA, BOA, gallic acid and infusions of flowers and leaves were determined. The phytomedicinal properties attributed to C. thyrsiflora Graham could be understood on the basis of its antibacterial activity
