PARTE UTILIZADA= Used part: Bulbo.

ACCIÓN FARMACOLÓGICA= Pharmacological action: Disentería, anticatarral.

COMPOSICIÓN QUÍMICA= Chemical composition: Volatile oils obtained by hydrodistn. of the tubers of two varieties (brown and black) of Cyperus esculentus L. (Cyperaceae) were analyzed by GC and GC-MS. Nine and 11 compds., representing 91.7-99.7% of the total volatile oils were identified, resp., from the brown and black varieties. The most representative compds. were alpha-pinene (70.5-75.5%) and alpha-thujene (5.2-10.2%).

ZONA GEOGRÁFICA= Geografical zone: Uruguay. 

DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

Cultivated and weedy clones of yellow nutsedge were analyzed using random amplified polymorphic DNA (RAPD) markers to assess the polymorphism within the species and determine if this approach was suitable for identification of cultivar and wild populations. The RAPD markers unambiguously identified all studied clones. Nei-Li similarities were computed and used in an unweighted pair group method using arithmetic average (UPGMA) cluster analyses. Cultivated and weedy clones were clustered in two groups, but two cultivated clones were more closely related to weedy clones than to cultivated clones. The results showed a high level of genetic variability among the clones tested, particularly among the cultivated ones. Identification of yellow nutsedge cultivars and analysis of genetic diversity within and among weedy populations is possible by using only a small number of primers. In this study, seven selected primers discriminated among the 10 tested clones.
