“…Moreover, TN contains hydrocarbon compounds such as B-Cymene, D-Limonene and Psi-limonene in ranged between 1.5-2.57% from total GC-Ms profile. This result is agree with Kubmarawa et al (2005) who reported that, TN contained high amounts were ρ-cymene (1.3-2.8%), limonene (1.3-2.8%), myrcene (1.7-1.8 %) and sabinene (1.0-6.9 %). B-Cymene, which has a biological role in antimicrobial activity, as well as two aromatic alcohols of O-thymol and menthol were identified in TN.…”

In recent time, there has been an increase interest to improve prebiotic material and probiotic bacteria mainly in food. This study aims to evaluate the effect of Jerusalem artichoke (JR) and Cyprus esculents (Tigernut or Chufa) (TN) as prebiotics source, to improve growth and survival of probiotic bacteria in yoghurt and as a preserved agent against the food borne bacteria in vitro. In addition, emphasis on improve nutritional value of dough using a new source of inulin by supplemented wheat flour with JR and TN. In vitro JR and TN were used as prebiotic for evaluation their effect as growth promoters for prebiotic bacteria (Lactobacillus plantarum, Lactobacillus curvatus and Bacillus subtilis) and evaluated antimicrobial activity against Staphylococcus aureus at different concentrations (5.0 and 10.0%). The results revealed that JR and TN contained of a sufficient amount of macronutrients carbohydrate, fiber and valuable amino acids. Sugar profile of these plants showed that, inulin was the most abundant polysaccharides in JR while TN was abundant in fructose. These polysaccharides (inulin and fructose) as considered as bioactive ingredients and prebiotic compounds. In addition, 10 % supplementation level of JR or TN resulted in greater growth rates of prebiotic bacteria, as well as showed stronger antimicrobial activity. Therefore, these results could suggest a preferential utilization of JR and TN in the people diet for improving the nutritional value and provide health benefits as functional foods, as well as considered economic and natural antimicrobial agent in food preservation.

“…Although, monoterpenes such as α-pinene, β-pinene, p-cymene, limonene, 1,8-cineole and transpinocarveol have been reported as constituents of Cyperus essential oils [7,25,30], the presence of 1,8cineole in large amount, as seen in our result, has not been previously reported. However, the composition of the essential oil of C. distans from South Africa shows that it is sesquiterpenoids rich, which makes it similar to other reported species of Cyperus growing in different parts of the world [6,7,[21][22][23][24][25][26][27][28][29].…”

“…Compositional studies of the essential oils of Cyperus species are available in the literature [6,7,[21][22][23][24][25][26][27][28][29][30]. The major constituents identified from most species were mainly sesquiterpenoids.…”

“…(formerly C. brevifolius ) and Kyllinga nemoralis (Hutch & Dalz.) (formerly C. kyllingia ) [13,14,15], suggesting that terpenoids may play an important role in defense against stress of members of Cyperaceae . Extracts and compounds from C. iria , a representative sedge species, have been used in traditional Chinese medicine for therapy of rheumatism, injury and fracture in China for a long time [16].…”

Terpenoids from Weedy Ricefield Flatsedge (Cyperus iria L.) Are Developmentally Regulated and Stress-Induced, and have Antifungal Properties

Ricefield flatsedge (Cyperus iria L.), a troublesome weed in rice production, actively adapts to ecological niches. In this study, terpenoids were identified as the dominant compounds from organic extracts of C. iria leaves. To understand the role of terpenoid production in plant development and resistance to abiotic and biotic stresses, the dynamics of terpenoid production at different developmental stages, and the regulation of these compounds by stresses were determined. Terpenoid production exhibited temporal and spatial specificity. During vegetative growth, the total concentration of sesquiterpenoids increased and reached a maximum at 70 d after germination, and then decreased until the emergence of inflorescence. Monoterpenoids were only detected from leaves 90 d after germination. During reproductive growth, the total concentration of sesquiterpenoids increased dramatically and mainly accumulated in inflorescences, indicating that the sesquiterpenoids were primarily produced in newly formed and actively growing tissues. The total amount of monoterpenoids, mostly accumulated in flowers, increased until 130 d after germination. Furthermore, accumulation of sesquiterpenoids in leaves was promoted significantly by methyl jasmonate (MeJA) and drought treatment. Infestation by beet armyworm (Spodoptera exigua, BAW) promoted the emission of total sesquiterpenoids significantly and induced the production of more monoterpenoids and sesquiterpenoids specifically. Furthermore, volatiles from C. iria leaves had an anti-fungal effect on Fusarium graminearum. The implications of our findings on the biosynthetic pathways leading to the production of sesquiterpenoids in C. iria as well as their potential as fungicides are discussed.
