The application of Spirulina platensis aqueous extract (SAE) in foliar spraying has been shown to promote plant growth and yield, as well modify the compositions bioactive chemicals various species. Curcuma longa is an antioxidant-rich medicinal herb that used a spice culinary additive. natural enhancer, SAE, C. plants was this study test effect SAE for increasing active chemical production. ef...

The application of exogenously applied salicylic acid plays important roles in improving the growth, yield, and bioactive compound compositions different plant species. Curcuma longa is a medicinal that commonly used as spice food additive, has antioxidant potential. In this study, an innovative strategy for enhancing active production was investigated by applying natural growth enhancer—namely...

The activity of several diarylheptanoid derivatives (curcuminoids) was previously evaluated against Leishmania amazonensis promastigotes and among them the most active compound was the [1-(4-methoxy-phenyl)-7-(3,4-methoxy-4-hydroxy-phenyl)-1,6-heptadien-3, 5-dione]. This derivative was chosen to be assayed in vivo in a treatment trial. For these experiments, the curcuminoid compound was used in...

In order to obtain detailed information on ground and excited states of curcumin and curcuminoids, as well as to understand the photobiological characteristics of them, their spectral and photophysical behaviors are investigated in various conditions. Various curcuminoids were obtained and their structures were determined by spectroscopic methods. In n-hexane, the absorption and fluorescence sp...

Objective(s): Curcuminoids, comprising curcumin, demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC), are bioactive phytochemicals with numerous pharmacological effects. Oral biological availability of curcuminoids is low due to the low aqueous solubility and rapid metabolism. This study aimed at fabricating a nanomicellar curcuminoid formula with enhanced pharmacokinetic properties. Materi...

In this report, we present the research results on using the conventional method and microwave technology to extract curcuminoid from turmeric roots originated in different regions of Northern Vietnam. This method is simple, yet economical, non-toxic and still able to achieve high extraction performance to get curcuminoid from turmeric roots. The detailed results on the Raman vibration spectra ...

The field of fluorescent boron complexes has witnessed tremendous developments in recent years. In that context, we have investigated two series of boron difluoride complexes based on 2′-hydroxychalcone and curcuminoid ligands that represent naturally occurring pigment structures. The dyes display significantly large Stokes shift values, indicating that an ICT state is involved as lower-energy ...
