“…The ash content was, however, higher in the leaves, followed by fruit and flower tissues (~7%). The value falls within the reference range of ash content in Gardenia fruit ( 30 ). Phytopigments are mainly classified into fat-soluble pigments, which are mainly present in the plastid of the plant protoplasm, and water-soluble pigments, which dissolve in the cell sap ( 6 ).…”

“…Among the solvent combinations tested, methanol gave the highest yield followed by DIH 2 O, ethyl acetate, and dichloromethane. Kesavan et al ( 30 ) reported a low yield of Gardenia extracts when low polar organic solvents (namely, ethyl acetate and dichloromethane) were used. The yellow pigment appeared in high polar organic solvents (methanol, DIH 2 O, and ethyl acetate), mainly from the fruit and floral tissues of Gardenia .…”

Recovery of Crocins From Floral Tissue of Gardenia jasminoides Ellis

In this research, a novel source of phytopigment crocins from fully open mature flowers of cape jasmine ( Gardenia jasminoides ) is introduced. Methanol and deionized water were appropriate solvents for pigment recovery with maximum yields of at least 17% from the floral tissue. Pigment separation by thin layer chromatography also confirmed the presence of the carotenoids, which dissolved well in these high-strength polar solvents, in fruit, flower, and leaf materials. The spectral patterns of the extracts from ultraviolet and nuclear magnetic resonance showed maximum absorption at ~420 nm and the chemical shift values were similar to those of crocetin aglycones (crocins) in the methanol extracts of a commercial source of yellow gardenia (fructus or fruit of Gardenia florida ). Chemical compositions were then evaluated using aqueous-phase capillary electrophoresis of the methanol extracts. The methanolic extracts of the flowers and fruit had 11 principal ingredients in common. Among these, crocetin and crocin 2 belong to the crocin group and are known to be the major components of commercial yellow Gardenia . This research not only demonstrates a sustainable means of raw material utilization for natural product recovery, but also encourages a movement toward an edible landscape for the community.

Objective: The present study was undertaken to establish the micromorphological characters of Talinum portulacifolium (Forssk.) Asch. ex Schweinf. belonging to the family Portulacaceae.Methods: The fresh plant parts were selected for micromorphological studies, and the air-dried plant powder was used for powder analysis as per the standard techniques [1-3].Results: Results revealed the presence of diagnostic characters like calcium oxalate crystals in the parenchyma cells of the leaf, which are druses with spiny surface that occurs in ordinary parenchyma cells. Stomata are paracytic which are present in both adaxial and abaxial surfaces of the leaf. The powder contains fragments of leaf epidermis, densely distributed stomata in laminar portions of the leaf.Conclusion: The present study provides the valuable information and also acts as pharmacognostical standards to standardize the study plant scientifically.

The inappropriate use of antibiotics and the inadequate control of infections have led to the emergence of drug-resistant strains. In recent years, metallo-pharmaceutics and metallic nanoparticles have been proposed as potential alternative antimicrobials due to their broad-spectrum antimicrobial properties. Moreover, recent findings have shown that combinations of transition metal compounds can exhibit synergistic antimicrobial properties. Therefore, the synthesis and design of bimetallic nanoparticles is a field worth exploring to harness the interactions between groups of metals and organic complex structures found in different microbial targets, towards the development of more efficient combinatorial antimicrobials composed of synergistic metals. In this study, we present a green synthesis of Ag–Fe bimetallic nanoparticles using an aqueous extract from the leaves of Gardenia jasminoides. The characterization of the nanoparticles demonstrated that the synthesis methodology produces homogenously distributed core–shell Ag–Fe structures with spherical shapes and average diameter sizes of 13 nm (± 6.3 nm). The Ag–Fe bimetallic nanoparticles showed magnetic and antimicrobial properties; the latter were evaluated against six different, clinically relevant multi-drug-resistant microbial strains. The Ag–Fe bimetallic nanoparticles exhibited an antimicrobial (bactericidal) synergistic effect between the two metals composing the bimetallic nanoparticles compared to the effects of the mono-metallic nanoparticles against yeast and both Gram-positive and Gram-negative multidrug-resistant bacteria. Our results provide insight towards the design of bimetallic nanoparticles, synthesized through green chemistry methodologies, to develop synergistic combinatorial antimicrobials with possible applications in both industrial processes and the treatment of infections caused by clinically relevant drug-resistant strains.
