Abstract. Rumape O, Kilo A, Ischak NI. 2022. Amethyst leaf extract as pest control and fertilizer for soybean plants. Biodiversitas 23: 3355-3363. (Datura metel L.) is a plant that grows develops in the Gorontalo area, people use it traditional medicine. This has natural insecticidal activity not yet known by general public. So far, results of research on insecticides from amethyst have only be...

Plants historically have served as models in drug development. The production of medicines and the pharmacological treatment of diseases began with the use of herbs. The antifungal activity of five different plants namely, Aegle marmelos, Carica papaya, Mentha arvensis, Nicotiana plumbaginifolia and Tamarindus indica were tested against plant pathogenic fungi Alternaria alternata. The plant ext...

BACKGROUND & OBJECTIVES Nigella sativa Linn. is extensively used in the Indian diasporas as spice, which may interact with co-administered drugs and affect their intestinal availability. The purpose of this study was to investigate the effect of Nigella on bioavailability of amoxicillin in animal model. METHODS Everted rat intestinal sacs were used for in vitro experiment to study the transfe...

Penicillium expansum Link causes an economically important postharvest blue mold disease in a number of fruits and vegetables. In the present study, this fungus was isolated from rotted grapes identified on morphological basis. Identification pathogen further confirmed molecular basis by using four different primer pairs namely ITS, β-tubulin, CMD CF under accession numbers MN752155, MN787831, ...

Peperomia pellucida (L.) Kunth has been studied as an anti-osteoporotic agent. However, there is no report about its estrogenic activity, which important for activity. Thus, the aim of this research was to study potency P. extracts. The activity extracts (n-hexane, ethyl acetate, ethanol, and water extracts) using E-screen assay confirmed with a molecular docking simulations. Further, presence ...

In previous studies, the relaxant effect of Tymus vulgaris has been demonstrated on guinea pig tracheal chains. Therefore, in the present study, the relaxant effects of n-hexane, dichloromethane, methanol and aqueous fractions of Tymus vulgaris on tracheal chains of guinea pigs were examined. The relaxant effects of four cumulative concentrations of each fraction (0.4, 0.8, 1.2 and 1.6 g%) in c...

Background: The enzyme tyrosinase is a copper-containing polyphenol oxidase, which is involved in melanogenesis. It catalyzes the conversion of tyrosine to melanin pigments in mammals. Tyrosinase plays an important role in enzymatic browning, which causes discoloration and loss economic value of many plant food products. This enzyme is widely distributed in fungi, higher plants and animals. Ob...

The hexane-1,6-diammonium cation of the title compound, C(6)H(18)N(2) (2+)·2NO(3) (-), lies across a crystallographic inversion centre and shows significant deviation from planarity in the hydro-carbon chain. This is evident from the torsion angle of -64.0°(2) along the N-C-C-C bond and thse torsion angle of -67.1°(2) along the C-C-C-C bonds. An intricate three-dimensional hydrogen-bonding netw...
