The antibacterial potency of the extracts of the seed of Garcinia kola (bitter kola) was investigated in this study against a panel of referenced, environmental and clinical bacterial strains. The killing rates of the active extract as well as their potential for combination antibacterial therapy with standard antibiotics were also elucidated using standard procedures. The aqueous and acetone extracts of the seed were screened for activity against 27 bacterial isolates. The aqueous extract exhibited activity mainly against Gram positive organisms with Minimum inhibitory concentration (MIC) val

Abstract:

The COVID-19 pandemic represented an unprecedented global emergency. Despite all efforts, COVID-19 remains a threat to public health, due to the complexity of mass vaccination programs, the lack of effective drugs, and the emergence of new variants. A link has recently been found between the risk of developing a severe COVID-19 infection and a high level of oxidative stress. In this context, we have focused our attention on natural compounds with the aim of finding molecules capable of acting through a dual antiviral / antioxidant mechanisms.

Abstract:

Present days lifestyles increase the number of free radicals in our body and predispose people to oxidative stress, responsible for the development of several diseases as well as aging. The need for inhibitors of oxidative processes has become essential. Plant-derived antioxidant compounds are preferred. Hibiscus sabdariffa L. belongs to the Malvaceae family. Its calyces contain anthocyanins, responsible for the antioxidant activity reported for the extracts. Moringa oleifera Lam. belongs to the Moringaceae family.

碩士<br>國立臺灣大學<br>食品科技研究所<br>96<br>Diabetes mellitus is a metabolism disorder characterized by chronic hyperglycemia due to inefficient action of insulin or insufficient production of insulin. One of the mechanisms proposed for diabetic complication is the formation of advanced glycation end products, known as AGE. AGE could bind with cellular receptors, increase oxidative stress and activate pathways that release proinflammatory compounds and cytokines, form irreversible AGE-proteins and finally modify proteins and enzymes and deactivate their functions. Lotus leaf and adlay have numerous bio

The maximum caffeic acid derivatives contents (1.13% dried weight) was obtained from the freeze-dried 0.7EtEs of PCfSPs, while those (90.6 g/mL 70% glycerol) was obtained from the 0.7GlEs of

But many key factors involved in the mechanism of dormancy are still not well known. The dormancy seeds of Prunus campanulata Maxim, a native species in Taiwan, was selected to study the mechanism of dormancy. We focus on the extracts of testa and endocarp of the seeds to elucidate the chemical roles on the seed dormancy of P. campanulata. There are many reports usually emphasizing the importance of embryo in controlling dormancy of plants such as Arabidopsis,

The objective of this study is to assess the antioxidant activity of ethyl acetate and methanol and its soluble fractions from grape skin, seed and leaf. The antioxidant activities were carried out using various antioxidant assays, including DPPH and ABTS free radical scavenging assays, reducing power assay, hydrogen peroxide scavenging assay and thiobarbi

The antioxidant, anti-inflammatory, anti-allergy, anti-viral and anti-cancer effects of phenolic compounds from perilla seed also have been reported in the past few years. Recently, phenolic compounds which existed in defatted perilla seed have been indicated with antimicrobial and antilipoxygenase activities. Although the defatted residue from perilla seed might be a kind of waste in oil and lipid indus

The contents of polyphenolic compounds and antioxidant capacity in the extracts were determined and inhibitive activities of α-amylase and α-glucosidase were also analyzed. In addition, the inhibition of glycation in BSA-Glucose and BSA-Methylglyoxal (MGO) systems were subjected to investigation. The results showed that using the 70% ethanol extraction method was able to obtain the maximum of total phenolic com

However, The sex endocrine system may be interfered by some life-styles and disease. It has been reported that many compounds of food may modulate the secretion or functions of sex hormones. These actions are generally recognized as safe or tardily effective. Therefore, it is potential to develop healthy food with regulatory effects for endocrine system. Adlay
