Optimization of solvent extraction of the leaves of Premna serratifolia and quantitation of remnaodoroside A by validated TLC-densitometric method
Introduction: The leaves of Premna serratifolia have been widely used in traditional medicine. Its major constituents were iridoid glycosides and phenolic compounds. Antioxidation was one of its reported bioactivities. The ...
Optimization and evaluation of microemulsions containing grape seed oil
Grape seed oil, obtained from grape seeds (Vitis Vinifera L.), is used in cosmetic products. It demonstrates antifungal, antioxidant, anti-inflammation, and antibacterial activities. Microemulsions are a type ...
Determination of antimicrobial activity from various plant parts of Typha angustifolia using Agar Disc Diffusion and Bioautography
Fruit, leaf, fruit stalk, and rhizome of Typha angustifolia, which is abundantly available in Thailand, were investigated for antimicrobial activities. The results showed that fruit ethanolic extract had high activity ...
Smartphone-based technique for the determination of a titration equivalence point from an RGB linear-segment curve with an example application to miniaturized titration of sodium chloride injections
A smartphone-based technique for determining the titration equivalence point from a linear-segment curve was developed for the first time. In this method, a titrant in an increasing microliter-volume was added to a set of ...
Development and evaluation of hydroxypropyl methylcellulose patches containing clindamycin for topical application
Clindamycin (CM) is the one of antibacterial drugs that can be used to treat acne vulgaris. The commercial products in form of solutions, creams, and gels cannot provide the exact amount of the drug and constant drug ...
Development and physico-chemical evaluations of clove oil microemulsions
Clove oil, extracted from dried floral buds of clove (Syzygium aromaticum), are used in topical products because it has antioxidant and antimicrobial activities. Microemulsions (ME) are stable emulsion which can be formulated ...
Development of clove oil in situ gels for buccal mucoadhesive
Clove oil is the volatile essential oil obtained from Syzygium aromaticum. Eugenol, which is the main component, has antimicrobial, antifungal activity and antioxidant. From antiseptic activity, clove oil can be used in ...
Investigating matrix interference in the pharmacopeial limit test for aluminum in citric acid: a re-examination, for revision of the method
In many pharmacopoeias, the limit test used for determining the level of aluminum in citric acid labeled for use in the manufacture of dialysate, is based on solvent extraction using 8-hydroxyquinoline and measurement of ...
Rapid and efficient microwave-assisted extraction of Caesalpinia sappan Linn. heartwood and subsequent synthesis of gold nanoparticles
Since microwave (MW)-assisted synthesis of gold nanoparticles (AuNPs) using Caesalpinia sappan (CS) extract as both a reducing and stabilizing agent is currently unavailable, a MW-based synthesis protocol was investigated ...
Effect of polyethylene glycol on cellulose acetate films designed for controlled porosity osmotic pump systems
This study aimed to investigate the properties of the films containing cellulose acetate and different amounts of polyethylene glycol 200 designed for controlled porosity osmotic pump systems. Polyethylene glycol 200 was ...
