The bullfinch Loxigilla barbadensis is an endemic passerine on the Caribbean island of Barbados that has only recently been taxonomically split from the Lesser Antillean bullfinch L. noctis. The trait that most clearly distinguishes L. barbadensis from L. noctis is the absence in the male of sexually dimorphic coloration of the body and throat feathers, with L. barbadensis males and females sha...

The present study focuses on the synthesis of stable metal oxide nanoparticles (MO-NPs) using Aloe Vera Barbadensis leaf extracts via a green route approach. MO-NPs were synthesized by interaction Aloe-Barbadensis extract with metaloxide salt and its azodye (Congo red). These NPs then characterized SEM (surface morphology), XRD (Crystallography structure, peaks MO-NPs), UV-Vis (Absorption spect...

A simple, precise, specific, accurate high performance thin layer chromatography method was developed for simultaneous estimation of aloe emodin and emodin from medicinal plants like Rheum emodi (Rhubarb), Barbados aloes (dried juice of Aloe barbadensis leaf) and Cassia alata (Candle bush). Thin layer chromatographic aluminum plates pre-coated with silica gel 60 F254 was used as the stationary ...

Tretinoin is the most effective available topical comedolytic agent, but topical application may lead to erythema, peeling and burning of the skin. During the past few decades many reports have documented an emergence of antibiotic resistance by Propionibacterium acnes during treatment of acne. Furthermore, systemic antimicrobials used in the treatment of acne have been causally associated with...

Aloe plants can be grown autotrophically in a maintenance-free, sterile, ex vitro environment. Excel, 15-5-15 plus minors fertilizer formulation and Plant Preservative Medium (PPM) biocide was used as a very economical basal medium. In vitro micropropagated plantlets were regenerated in Excel media with 2 g /L sucrose and 2.2 μM 6-Benzylamino purine (BA) and used to initiate ex vitro cultures i...

The phytochemical profile of Aloe barbadensis Mill. and Aloe arborescens Mill. was investigated using colorimetric assays, triple quadrupole and time-of-flight mass spectrometry, focusing on phenolic secondary metabolites in the different leaf portions. Hydroxycinnamic acids, several characteristic anthrones and chromones, the phenolic dimer feralolide and flavonoids such as flavones and isofla...
