    An ethnobotanical field study focusing on traditional wild food botanical taxa was carried out in Kaniguram, South Waziristan, Pakistan, among Ormur (or Burki or Baraki) peoples, which represent a diasporic minority group, as well as among the surrounding Pashtuns. Through sixty semi-structured interviews, fifty-two wild food plants (taxa) were recorded, and they were primarily used raw as snacks and cooked as vegetables. Comparative analysis found a remarkable overlap of the quoted plant uses between the two studied groups, which may reflect complex socio-cultural adaptations Ormur speakers faced. Ormur people retain a rich knowledge of anthropogenic weeds and the phytonyms reveal important commonalities with Persian and Kurdish phytonyms, which may indicate their possible horticultural-driven human ecological origin from the Middle East. Some novel or rare food uses of Cirsium arvense, Nannorrhops ritchiana, Periploca aphylla, Perovskia atriplicifolia, Viscum album, Oxalis corniculata and Withania coagulans were documented. Since the Ormuri language represents a moribund language, still spoken by only a few thousand speakers in NW Pakistan and Afghanistan, it is recommended that the traditional bio-cultural and gastronomical heritage of this minority group be appropriately protected and bolstered in future rural development programs

    The traditional medicine still plays an important role in the primary health care in Yemen. The current study represents the investigation of 16 selected plants, which were collected from different localities of Yemen. The plants were dried and extracted with two different solvents (methanol and hot water) to yield 34 crude extracts. The obtained extracts were tested for their antimicrobial activity against three Gram-positive bacteria, two Gram-negative bacteria, one yeast species and three multiresistant Staphylococcus strains using agar diffusion method, for their antioxidant activity using scavenging activity of DPPH radical method and for their cytotoxic activity using the neutral red uptake assay. In addition, a phytochemical screening of the methanolic extracts was done. Antibacterial activity was shown only against Gram-positive bacteria, among them multiresistant bacteria. The highest antimicrobial activity was exhibited by the methanolic extracts of Acalypha fruticosa, Centaurea pseudosinaica, Dodonaea viscosa, Jatropha variegata, Lippia citriodora, Plectranthus hadiensis, Tragia pungens and Verbascum bottae. Six methanolic extracts especially those of A. fruticosa, Actiniopteris semiflabellata, D. viscosa, P. hadiensis, T. pungens and V. bottae showed high free radical scavenging activity. Moreover, remarkable cytotoxic activity against FL-cells was found for the methanolic extracts of A. fruticosa, Iris albicans, L. citriodora and T. pungens. The phytochemical screening demonstrated the presence of different types of compounds like flavonoids, terpenoids and others, which could be responsible for the obtained activities

    In the course of an ethnobotanical study on fungi used in Yemeni ethnomedicine the fungus Podaxis pistillaris (Podaxales, Podaxaceae, Basidiomycetes) was found to exhibit antibacterial activity against Staphylococcus aureus, Micrococcus flavus, Bacillus subtilis, Proteus mirabilis, Serratia marcescens and Escherichia coli. In the culture medium of P. pistillaris three epidithiodiketopiperazines were identified by activity-guided isolation. Based on spectral data (NMR, ESI-MS and DCI-MS) their identity was established as epicorazine A (1), epicorazine B (2) and epicorazine C (3, antibiotic F 3822), which have not been reported as constituents of P. pistillaris previously. It is assumed that the identified compounds contribute to the antibacterial activity of the extract
