“…Yacon also possesses the properties to treat kidney complaints and skin-rejuvenating activity. Fructooligosaccharides are the products recognised and used as food ingredients and prebiotics (Pedreschi et al 2002). Pedreschi et al (2002) found that Lactobacillus plantarum NRRL B-4496 and L. acidophilus NRRL B-1910 completely utilised the GF 2 molecule while Bifidobacterium bifidum was apparently able to utilise molecules with higher DP.…”

Yacon [Smallanthus sonchifolia (Poepp. et Endl.) H. Robinson], a native plant of the Andes, belongs to the family Compositae (Asteraceae) and it represents a traditional crop of the original population of Peru used in traditional medicine. A major portion of tuberous root biomass is composed of water (> 70% of fresh weight). Saccharides, especially oligofructans, form 70-80% of dry weight, protein content ranges between 0.3% and 3.7%. Fructooligosaccharides of inulin type β (2→1), mainly oligomers (GF 2 -GF 16 ), are known for their ability to keep the colon healthy. Yacon sweetness is predominantly caused by fructose, which is by some 70% sweeter than sucrose. Other oligosaccharides are 1-kestose and nystose. Diabetics and persons suffering from digestive problems are recommended to consume yacon because its sugars are not available from the small intestine. The mean tuberous root composition per 100 g of fresh matter is 81.3, 13.8, 0.9, 1.0, 0.1 and 1.1 g of water, saccharides, fibre, proteins, lipids and ash, respectively. Mean mineral contents per 100 g of fresh matter are 334, 34, 12, 8.4, 0.4 and 0.2 mg of potassium, phosphorus, calcium, magnesium, sodium and iron, respectively. Vitamins B 1 , B 2 , C, β-carotene and polyphenols in the same weight are present at mean concentrations 0.07, 0.31, 5.0, 0.13 and 203 mg, respectively. Yacon can be considered an industrial crop, particularly as a source of inulin. The used forms are flour, syrup, extract from tuberous roots and moreover leaf extract for the preparation of yacon infusion with hypoglycaemic effect. In yacon leaves di-and sesquiterpenes with protective effects against insects are present, among them mainly ent-kaurenic acid (ent-kaur-16-en-19-oic acid) and its derivative -15-α-angeloyloxy-entkauren-19-oic acid 16-epoxide. Other components are polyphenolic antioxidants, esp. hydroxycinnamic acids and chlorogenic acid. A new antifungal melampolide -sesquiterpene lactone named sonchifolin, as well as three known melampolides, polymatin B, uvedalin and enhydrin, were isolated from leaf extracts of yacon. Three major phytoalexins were isolated: 4'-hydroxy-3'-(3-methylbutanoyl)acetophenone, 4'-hydroxy-3'-(3-methyl-2-butenyl)acetophenone and 5-acetyl-2-(1-hydroxy-1-methylethyl)benzofuran.

“…En la inulina de origen vegetal, las unidades de fructosas enlazados a la glucosa terminal puede variar desde algunas unidades hasta 70, lo que significa que la inulina es una mezcla de oligómeros y polímeros, definiéndose como un polifructano con grado de polimerización (DP) mayor a 30 unidades (Pedreschi et al, 2003;Ricca et al, 2007;Seminario et al, 2003).…”

Recibido 04 agosto 2010; aceptado 22 octubre 2010 ResumenEn este trabajo se han revisado los principales avances alcanzados en los últimos veinte años, en el estudio de la fermentación de cepas de Kluyveromyces marxianus para la producción de la enzima inulinasa a partir de inulina pura y fuentes de inulina y la determinación de las propiedades y características de la enzima. Con el propósito de recopilar y esclarecer el mayor conocimiento de ésta área, la investigación de ésta materia ha sido dividida en tres partes: sustratos fuentes de inulina; producción microbiana de inulinasa y caracterización y propiedades de la inulinasa. Se discute la información existente sobre los microorganismos capaces de producir inulinasa los que han sido publicados con datos de rendimiento y en particular las condiciones de fermentación de cepas de Kluyveromyces marxianus para la producción de inulinasa a partir de varias fuentes vegetales de inulina. Se concluye que si bien es cierto existen cepas de Kluyveromyces marxianus capaces de producir satisfactoriamente inulinasa, la investigación para una fuente vegetal de inulina económicamente interesante todavía está en curso. Palabras clave: Kluyveromyces marxianus, inulinasa, inulina. AbstractIn this work the principal advances have been checked reached in the last twenty years, in the study of the fermentation of strains of Kluyveromyces marxianus for the production of the enzyme inulinase from inulin pure and sources of inulina and the determination of the properties and characteristics of the enzyme. With the aim of gathering and clarifying the greater knowledge of this one area, the investigation of this matter has been divided into three principal parts; substrate sources of inulin; microbial production of inulinase and characterization and properties of the inulinase. There is discussed the existing information about the microorganisms capable of producing inulinase those who have been brought by information of performance and especially the conditions of fermentation of strains of Kluyveromyces marxianus for the production of inulinase from several vegetable sources of inulin. One concludes that though it is true there exist strains of Kluyveromyces marxianus capable of producing satisfactorily inulinase, the investigation for a vegetable source of inulin economically interesting still is in process.

“…Since humans have no enzyme capable of hydrolyzing the β(2→1) bond, these fructans also serve as dietary fiber (Ojansivu et al, 2011). Recently, oligofructans have been classified as prebiotics (Pedreschi et al, 2003). These compounds are transported to the colon and fermented by selected species of gut micro-flora, especially Bifidobacterium and Lactobacillus, both indicators of a balanced gut flora.…”

Yacon (Smallanthus sonchifolius) tubers and leaves have been used widely as foodstuff and as remedy for urinary ailments, muscle pain, hyperlipidemia and diabetes mellitus. Recent studies have investigated on isolating active components for their anti-cancer potential against melanoma, cervical cancer and colon cancer. In this study, the cytotoxicity potential of hexane, methanol and DCM extracts of yacon leaves was assessed against MCF-7 (breast cancer), HT-29 (colon cancer) and HDFn (normal human dermal fibroblast) cell lines by using AlamarBlue ® assay. Results showed significant reduction in cellular viability of MCF-7 cell lines caused by hexane, methanol and DCM extracts in a dose dependent manner, with DCM being the most potent. The DCM extract also produced significant cytotoxic activity against HT-29 cells, with IC 50 lower than 5-fluorouracil. Effect on HDFn showed that three yacon extracts produced significantly lower cytotoxicity compared to drug controls with the DCM extract showing the least toxicity.
