Background: Considering the increasing resistance of bacteria to antibiotics and the presence of antibacterial agents in plantsObjectives: the aim of this study was the antimicrobial and antibiofilm activity of Tecomella undulata and Momordica charantia ethanol and aceton leaf extract on antibiotic resistance Acinetobacter baumannii.Methods: The leaves of Tecomella undulata and Momo...

Seed coat morphology of Lemmonia californica. long held to be a relative of Nama. was examined using scanning electron microscopy. Its seed coat exhibits reticulum cells with undulate cell walls and columnar radial wall thickenings. Seed coat structure in nine species of Nama. N. demissum. N. aretioides. N. densum. N. parviflorum. N. pusillum. N. depressum. N. dichotomum. N. sericeum and N. ori...

1. Subject and source Tecomella undulata (Smith) Seem. commonly known as`Rajasthan Teaka is one of the codominant species in the desert of western Rajasthan (Arya et al. have been reported from this plant. 3. Present study The concentrated petroleum ether extract prepared from the air dried leaves of T. undulata by Soxhlet apparatus, was chromatographed over a column of silica gel.

Betulinic acid (BA) is a pentacyclic triterpenoid acid obtained from the stem bark of Tecomella undulata Seem. (Bignoniaceae). Development of an efficient extraction method for the isolation of BA is important as it has a wide range of pharmacological activity. A Box-Behnken design (BBD) was used to investigate the effect of extraction variables such as temperature (30-60 °C), time (4-8 h) and ...

Many species of macroalgae have flat, strap-like blades in habitats exposed to rapidly flowing water, but have wide, ruffled "undulate" blades at protected sites. We used the giant bull kelp, Nereocystis luetkeana, to investigate how these ecomorphological differences are produced. The undulate blades of N. luetkeana from sites with low flow remain spread out and flutter erratically in moving w...

In India, family Bignoniaceae is represented by 21 genera and about 25 species including the non indigenous ornamental plants. The genera of Tecomella are a monotypic genus shrub/tree of the arid zone region in India. The natural stands of Tecomella undulata are restricted to the western parts and a few to southeastern parts of Pakistan. The species has been identified as an important for envir...

– The achene morphology of 20 taxa in five sections of Polygonum s.l. from Thailand was studied and compared in detail using stereoscopic light and scanning electron microscopy. The achene of all Thai taxa is typically lenticular or triangular in shape. Three different morphological types are described according to the features of the achene surface; smooth-undulate, a star-like form and reticu...
