Abstract:

A systematic study on extraction of Hibiscus sabdariffa was carried out for the first time using different solvents (water, methanol, ethyl acetate and hexane) in the presence and absence of formic acid, using different extraction times and temperatures. The extracts were analysed for total phenol content, antioxidant capacity using DPPH, FRAP and TEAC assays, and total monomeric anthocyanin content. In addition, specific anthocyanins were determined using HPLC and LC-MS. The results showed the highest antioxidant capacities were obtained by extracting using water, with or without formic acid,

O Hibiscus pernambucensis Arruda (HpA) é uma planta da família Malvaceae, típica de clima tropical de ecossistemas de mangues. A infusão das flores do HpA apresenta propriedades antioxidantes, decorrentes da vitamina E, flavonóides, quercetina e taninos. Há estudos mostrando que os campos eletromagnéticos de ultra-alta-freqüência (CEMUAF) podem provocar danos à saúde. Estes danos acontecem por indução de estresse oxidativo às células. O presente estudo visa verificar o efeito antioxidante das flores de HpA sobre o fígado e o córtex cerebral de ratas expostas aos CEMUAF durante a gestação e a l

Abstract:

There has been a lot of interest in Roselle (Hibiscus sabdariffa L.), called Bissap in Senegal, hibiscus recently because of consumer interest in nutraceutical products. However, beverages made from hibiscus have a short self-life due to anthocyanin and flavor degradation. The purpose of our study was first to assess the impacts of water, extraction procedure and origin on the anthocyanins of hibiscus extracts and secondly, to examine the impacts of freeze-drying on the anthocyanins and the volatiles compositions of hibiscus extracts. For the first experiment, a 2x3 factorial design was used w

Abstract:

Purple Hibiscus, a novel by third-generation Nigerian author Chimamanda Adichie, appears at first glance to be a simple work of adolescent fiction, a bildungsroman in which a pair of siblings navigate the typical challenges of incipient adulthood: social ostracism, an abusive parent, emerging desire. However, the novel's setting-a revolutionary-era Nigeria-is clearly intended to evoke post-Biafra Nigeria, itself the setting of Adichie's other major work, Half of a Yellow Sun. This setting takes Purple Hibiscus beyond the scope of most modern adolescent fiction, creating a complex allegory in w

Thesis (MTech (Biomedical Technology))--Cape Peninsula University of Technology, 2015.<br>Cancer is the leading cause of death in both developed and developing countries. In particular, breast cancer is regarded as the most common neoplastic disease in females and accounts for the high mortality rates in women. Increased mortality rates could be attributed to ineffective current cancer treatment modalities that have been implicated to cause multidrug resistance, high toxicity and induction of several side effects. In addition, oxidative stress appears to play a role in the development of breas

Abstract:

The pink hibiscus mealybug (PHM), Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) was investigated with regard to damage caused to hibiscus by feeding, dispersal of nymphs, evaluation of management tactics, and the use of sex pheromone based monitoring in southern Florida from 2005 to 2008. Understanding the ability of PHM to locate and colonize new hosts, and the response of hosts is essential to optimized monitoring and management strategies. Investigation of the onset and severity of PHM feeding symptoms by Hibiscus rosa-sinensis L. showed that severity of symptoms differed am

Abstract:

The purpose of this essay is to conduct a character analysis on Eugene Achike from Chimamana Ngozi Adichie’s novel Purple Hibiscus, to see whether or not the character is used by Adichie as a portrayal of colonial Nigeria and its values. I have done this by looking at the themes of violence and hypocrisy in relation to Eugene’s language usage, religious attitude, and behaviour towards others, and comparing these aspects of his personality with the attitudes shown by colonialists in colonial Nigeria. The more important issues that prove Eugene’s character is a portrayal of colonial Nigeria are:

Abstract:

Developing countries pay a high price for water treatment due to importation of water treatment chemicals. Today, more than 663 million people lack access to a clean water supply which results in many deaths. Hibiscus plant seeds, namely Okra, Sabdariffa and Kenaf were investigated to identify their suitability as alternative water treatment materials to provide clean water supply to people in developing countries. Coagulation and disinfection ability of the extracts were assessed using a jar tester and Collilert-18 Quanti-Tray methods whereas dissolved organic carbon (DOC) test was performed

Abstract:

Thing theorist Bill Brown writes that “the thing names less an object than a particular subject-object relation.” This article examines the subject-object relation between African things and African bodies in Nigerian author Chimamanda Ngozi Adichie's first novel, Purple Hibiscus. While the main character, Kambili, eventually learns to assimilate Western Catholicism into her Nigerian reality, her Christian fundamentalist father, Eugene, uses Catholicism to justify his self-hating destruction of African things and bodies. This article argues that both reactions are rooted in the characters' ab
