“…The moisture content of the fresh sweet potato tubers was approximately 70 %, and this result was similar to the results reported by Rumbaoa et al (2009). After baking, each tuber lost approximately 10.5 % of its weight because of moisture evaporation.…”

The objective of this study was to evaluate the influence of sugar composition on the sensory attributes of seven baked sweet potatoes. The sugar composition was analyzed using high performance liquid chromatography. Results showed that the total sugar content of baked sweet potatoes increased significantly because of the formation of maltose. The maltose content dramatically increased after baking, and became the major sugar component of baked sweet potatoes. On the other hand, baked sweet potatoes were evaluated on a 7-point hedonic scale for sensory analysis. Overall acceptability results showed that the panelists preferred baked CYY95-26 and TNG66 over the other baked varieties. Because the correlation between overall acceptability and sweetness was the highest (r00.69, p<0.01), sweetness was determined as the most important factor determining the overall acceptability of baked sweet potatoes. Although sugar composition changed on baking, the overall acceptability of baked sweet potatoes was highly associated with the sucrose content.

“…Sweet potatoes (Ipomoea batatas (L.) Lam) contain substantial amounts of nutrients, such as vitamin C and β-carotenes, and are a very important food source in Asia and developing countries (Lien et al 2012;Rumbaoa et al 2009). Baking is the most popular method of cooking sweet potatoes (Collins et al 1995).…”

A microplate assay and a thin-layer chromatography (TLC) "in situ" assay based on the Ellman assay was used to screen for acetylcholinesterase inhibitors from ethyl acetate and methanol extracts of Brazilian medicinal plants of families that, according to the literature, have traditional uses that might be connected with acetylcholinesterase inhibition. Eighteen species belonging to Convolvulaceae, Crassulaceae, Euphorbiaceae, Leguminosae, Malvaceae, Moraceae, Nyctaginaceae and Rutaceae families were tested. The most active plants were Ipomoea asarifolia (IC 50 = 0.12 mg/mL), Jatropha curcas (IC 50 = 0.25 mg/mL), Jatropha gossypiifolia (IC 50 = 0.05 mg/mL), Kalanchoe brasiliensis (IC 50 = 0.16 mg/mL) and Senna alata (IC 50 = 0.08 mg/mL). The most promising extracts were the Jatropha gossypiifolia and Senna alata species assuming there were compounds with a similar activity to galanthamine, which should contain about 1% of an active compound, or if present at lower levels even more active compounds than galanthamine (IC 50 = 0.37 x 10 -3 mg/ mL) should be present.Keywords: Brazilian medicinal plants, Alzheimer's disease, acetylcholinesterase inhibitors, microplate assay. Plantas medicinais brasileiras promissoras para inibição da acetilcolinesterase ResumoOs ensaios de microplaca e cromatografia em camada delgada com base no ensaio de Ellman foram usados para triagem de inibidores da acetilcolinesterase dos extratos acetato de etila e metanol de plantas medicinais brasileiras de famílias que, segundo a literatura, tem usos tradicionais que podem estar relacionadas com a inibição da acetilcolinesterase, enzima associada ao mal de Alzheimer. Dezoito plantas das famílias: Convolvulaceae, Crassulaceae, Euphorbiaceae, Leguminosae, Malvaceae, Moraceae, Nyctaginaceae e Rutaceae foram testadas. As espécies mais ativas foram Ipomoea asarifolia (CI 50 = 0,12 mg/mL), Jatropha curcas (CI 50 = 0,25 mg/mL), Jatropha gossypiifolia (CI 50 = 0,05 mg/mL), Kalanchoe brasiliensis (CI 50 = 0,16 mg/mL) e Senna alata (CI 50 = 0,08 mg/mL). Os extratos mais promissores foram os das espécies Jatropha gossypiifolia e Senna alata, assumindo a presença de compostos com atividade semelhante à galantamina que deve conter cerca de 1% de um composto ativo, ou se presentes em menores níveis ainda mais compostos ativos que a galantamina (CI 50 = 0,37 x10 -3 mg/mL) devem estar presentes.Palavras-chave: plantas medicinais brasileiras, doença de Alzheimer, inibidores da acetilcolinesterase, microplaca.

Hawthorn fruit is a conventional medicine used in treating cardiovascular diseases. Its therapeutic effects may relate to its antioxidant compounds. In this study, we evaluated the antioxidant activity of CH 2 Cl 2 , EtOAc, n-butanol and water fractions from 70% methanolic hawthorn fruit extract by total phenolic and flavonoid contents, total antioxidant activity, DPPH free radical scavenging activity, superoxide radical scavenging activity, reducing power assay, lipid peroxidation inhibitory activity and protective effect against hydroxyl-radical-induced DNA damage. Results showed that the EtOAc fraction contained significantly greater antioxidant activities than other fractions, which suggests that the potent EtOAc fraction should be used for further studies to identify the antioxidant compounds.
