Saudi Arabia is rich in Juniperusprocera Hochst. ex Endl (Cupressaceae) as a medicinal plant. Its known as Arar, its present southwards, KSA. It's used as traditional medicine in the southwestern, KSA. The aim was according to "Saudi Arabian Customs" in using wild-plant extract for treatment and prevention of infectious-pathogens. That was to use Juniperusprocerafrom Ranyah, KSA to eliminate infectious-pathogens that were isolated from patients in the same area. This was the use may reduce the use of chemicals, as well it may be an alternative to chemotherapy. Practice included preparation of wild-plant extract, preparation of infectious-pathogens, interaction to wild-plant extract, and direct total cell count by "Bread Test". Juniperusprocera one crude concentration killed all infectious-pathogens during one day. Lower Juniperusprocera crude extract concentrations eliminated infectious-pathogens within more than one day. The mean number of dead sells / mL of Staphylococcus sp., Streptococcus sp, and Streptococcus pyogenes were (84.9 / mL, 87.0 / mL, and 77.8 / mL). The mean percent of dead cells were (80.0%, 82.0%, and 73.4%). The meannumber of dead sells / mL of Salmonella sp., Shigella sp, and Escherichia coli were (72.6 / mL, 76.1 / mL, and 79.0 / mL). The mean percent of dead cells were (68.5%, 71.8%, and 74.5%). The mean number of Candida albicans dead sells / mL was 69.3 / mL, the mean percent of dead cells was 65.4%. It was concluded that found from the results, the Juniperusprocera extract was preferred "Saudi Arabian Customs" to be used in three quarter and one crude concentration, as the infectious-pathogens eliminating within one day. It was recommended that the Juniperusprocera extract will be used for herbal treatment according to "Saudi Arabian Customs". That will be remark and follow-up through the "Official Herbal Treatment Dept.". That will appropriate the doses will estimate for each patient to eliminate and protect against the infectious-pathogens.

The increasing spread, persistence, and prevalence of multidrug-resistant bacterial strains has become a significant global public health challenge, necessitating the need for novel, potent, and alternative antimicrobial agents, particularly from medicinal plants. The study determined the bioactive phytochemical constituents and antibacterial activities of the aqueous leaf extracts of Vernonia amygdalina (ALEVA) and Ocimum gratissimum (ALEOG). In ALEVA using the agar-well diffusion method. The ALEVA contained 35 identified compounds, with cis-thujopsene (20.99%), acetic acid (20.77%), and butanoic acid, 2-methyl (12.87%) being the most abundant. Ethosuximide and cyclohexane, 1, 3-butadienylidene were detected in small amounts. The ALEOG had 44 compounds, with butanoic acid, 3-methyl (13.89%), thymol (12.43%), and butanoic acid, 2-methyl (7.22%) in the highest concentrations, while 1H-cyclopenta[a] pentalen-7-ol and 9-octadecynoic acid methyl ester were present in small amounts. The ALEOG and ALEVA showed significant (p < 0.05) inhibition at 40 mg/mL against Helicobacter pylori and other bacterial isolates, with a highest mean (x S.D.) inhibition zone diameter of 17.5 0.5 mm and 18.2 1.1 mm, respectively. The minimum inhibitory concentrations (MIC) values of ALEVA and ALEOG for the isolates ranged between 5 g/mL and 40 g/mL; the minimum bactericidal concentrations (MBC) values of ALEVA and ALEOG for the isolates ranged between 5 g/mL and 80 g/mL, with an MBC/MIC of 4. The study has demonstrated that aqueous leaf extracts from O. gratissimum and V. amygdalina possess significant antibacterial activity, supporting their traditional medicinal uses.

This study aims to characterize and identify the genus of Ipomoea in the Greater Kediri area. The research was conducted in the Greater Kediri area which includes Kediri Regency and City, Nganjuk Regency, Blitar Regency and City, Tulungagung Regency, and Trenggalek Regency of East Java from January to June 2024 in an explorative descriptive manner. Sampling was done by snowball and purposive sampling. The observed characters include the morphological structure of roots, stems, leaves, flowers, fruits, and seeds. Plant identification was carried out referring to the Ipomoea genus Identification Key. The tools and materials used were ruler, razor/cutter, camera, stereo microscope, stationery, and plants of Ipomoea genus that were found. Ipomoea genus found in Greater Kediri area were 12 types, namely: Ipomoea batatas, Ipomoea carnea, Ipomoea aquatica, Ipomoea reptans, Ipomoea triloba, Ipomoea lacunosa, Ipomoea obscura, Ipomoea quamoclit, Ipomoea quinquefolia, Ipomoea pes-tigridis, Ipomoea pes-caprae and Ipomoea tricolor. Because of the wide area of research, this research is continued and if new species are found, they will be collected and added to the database of Ipomoea genus members in the Greater Kediri area.
