BioSMART : Journal of Biological Science, 2020Co-Authors: Maya Irawati, Sugiyarto Sugiyarto, Widya MudyantiniAbstract:The mains of this research were to study the effect of water and ZA fertilizer application and their interaction to growth and content of leaves nitrogen (N) of new cocoyam (Xanthosoma sagittifolium Schott.). Water and nitrogen are two limited factors for plant growth. Generally, soil gets loose N easily, so the soil needs the match fertilizer. Available water soil is the important factor to plant physiology process, and it helps N absorption. The factorial experiment was arranged on randomized completely design. First factor was water application (25%, 50%, and 75% of maximum soil water content). Second factor was ZA fertilizer dosage (0, 0,32, 0,64, and 0,96 g/polybag). The measured variables were plant height, total leaf, leaf area index, wet weight of plant, dry weight of plant, root shoot dry weight ratio, wet weight of tuber, dry weight of tuber, total leaves nitrogen, and environmental factors. The result showed that the increasing of water application until 75% of maximum soil water content and ZA fertilizer application until 0,96 g/polybag increased growth and leaves N content of new cocoyam. Interaction of optimal water and ZA fertilizer to the growth was water application 75% and ZA fertilizer dosage 0,96 g/polybag. The nitrogen content of leaves optimum in water application 50%, and ZA fertilizer dosage 0,96 g/polybag. Keywords: growth, nitrogen, Xanthosoma sagittifolium Schott., water, ZA fertilizer

taioba Xanthosoma sagittifolium leaves nutrient composition and physiological effects on healthy rats
Journal of Food Science, 2013Co-Authors: Elisa De Almeida Jackix, Elisa Bernardes Monteiro, Helena Fonseca Raposo, Emerielle C Vanzela, Jaime AmayafarfanAbstract:Several studies have shown that fruits and vegetables contribute to protect against degenerative pathologies such as cardiovascular diseases, diabetes, and cancer, mainly due to the presence of dietary fiber (DF) and polyphenols. Taioba (Xanthosoma sagittifolium) is an edible aroid widely grown in many parts of Africa, America, and Asia. The tubers portions of taioba are widely consumed; however, the leafy portions are generally discarded, despite their high nutritive value. In this study, we have partly characterized the DF of lyophiized taioba leaf (LTL), and assessed the possible protective effects on biochemical parameters and on bile acid (BA) production in colon and cecum, when fed to healthy rats for 4 wk. Forty-five Wistar rats were assigned to either of 5 groups: group 1 received AIN 93G diet (CG: Control); group 2 received AIN 93G containing 2.5% of cellulose + 2.5% inulin (CEIN_5%); group 3 received AIN 93G containing 2.5% of cellulose + 2.5% taioba fiber (CETA_5%); group 4 received AIN 93G containing 5% cellulose + 2.5% taioba fiber (CETA_7.5%); group 5 received AIN 93G containing 5% cellulose + 2.5% of inulin (CEIN_7.5%). LTL showed high contents of total fiber, predominantly comprising insoluble DF with glucose as the major monomer. Rats receiving LTL had increased fecal mass and fat excretion, and improved BA profiles by diminishing the proportion of secondary acids, thus suggesting that consumption of taioba leaf may have the property of lowering the risk of colon cancer. Practical Application The present study gives new and valuable information about nutrient composition and some of the in vivo functional properties of taioba leaves. The results of this research showed that the taioba leaf contributed to the removal of dietary fat, and reduced the concentrations of colon and cecum secondary bile acids, which are associated with colon cancer. The positive effects may be related to a synergy between the fiber and other bioactive substances.

cholesterol reducing and bile acid binding properties of taioba Xanthosoma sagittifolium leaf in rats fed a high fat diet
Food Research International, 2013Co-Authors: Elisa De Almeida Jackix, Elisa Bernardes Monteiro, Helena Fonseca Raposo, Jaime AmayafarfanAbstract:Abstract The consumption of vegetables has been correlated with reduced risk of chronic non-communicable diseases due to the high fiber content and bioactive compounds found in vegetables. The arrowleaf elephant ear ( Xanthosoma sagittifolium ), which is known in Brazil as taioba , is a common plant in tropical America. Although its leafy portion possesses a high nutritional value, it is not widely consumed and has not been well studied. This study assessed the effect of lyophilised taioba leaf (LTL) as a hypolipidemic and prebiotic agent. Thirty-two Wistar rats were assigned to four groups: group 1 was fed a high-fat diet containing 3.67% (w/w) cellulose (low cellulose — LCEL); group 2 received a high-fat diet supplemented with 10% (w/w) cellulose (CEL); group 3 received a high-fat diet supplemented with 10% (w/w) inulin (INU); and group 4 was fed a high-fat diet supplemented with 28.4% LTL (TAI) to provide 10% (w/w) taioba fiber. The groups were fed their respective diets for 4 weeks. The addition of LTL to the diet resulted in reduced weight gain, reduced liver fat, and increased fecal mass and lipid, in addition to higher fecal short chain fatty acid and bile salt concentrations, compared to the LCEL group. Additionally, only the TAI group exhibited a lower serum cholesterol concentration and a higher body ash content (p
