The aim of the present study was to evaluate the locomotor and diuretic activities of both aqueous and alcoholic extracts of leaves of Epipremnum aureum (AQEEa and ALEEa) in experimental animals. Locomotor activity was evaluated by actophotometer and diuretic activity was evaluated using Lipschitz test model in rats. Preliminary phytochemical screening showed the presence of alkaloids, flavonoids, terpenoids and saponins. Intra peritoneal administration of AQEEa and ALEEa at doses 200mg/kg produced significant (P< 0.01) CNS depression by reducing locomotor activity while it showed a significant (P< 0.01) increase in the urine volume when compared to control. Thus, in conclusion the AQEEa and ALEEa have a significant CNS depression action by reducing locomotor and diuretic action in rats.

SummaryThe karyotypes in 3 morphological forms of Typhonium trilobatum (L.) Schott such as the Green form, the Dark purple form and the Light purple form were compared after staining with orcein and CMA. The Green form and the Light purple form were found to possess 2n ϭ18 chromosomes. However, 2n ϭ17 chromosomes were observed in the Dark purple form. One chromosome in pair IX was absent in this form. The karyotypic features revealed that the Dark purple form might be originated from the Green form as monosomic. The centromeric formula was determined 16mϩ2ac in the Green form, 11mϩ4smϩ2ac in the Dark purple form and 13mϩ5sm in the Light purple form. The Dark purple form showed more heterogeneous karyotype and may be considered as more advanced than the other 2 forms. No CMA band was found in the Green form. The Dark purple and the Light purple forms were found to possess distinct CMA banding pattern. With the help of CMA banding, it was possible to identify some chromosomes in these 2 forms. Few chromosome pairs in both the forms showed heteromorphicity in respect of CMA banding pattern indicating the occurrence of structural aberration. Morphology, distinct karyotypic features and CMA banding pattern suggested for placing the Green form in different taxonomic rank, while the Dark purple form might be considered as a monosomic variety of Typhonium trilobatum.

“…However, in Bangladesh this species has 4 different morphological forms (Ara 2001). These are: i) Sagittate form, ii) Lamina dissected form, iii) Entire lamina margin form and iv) A mixed form of sagittate and lamina dissected (Sultana et al 2006).…”

“…The 2 species of this genus are Lasia spinosa (L.) Thwaites and L. concinna Alderw. Lasia spinosa has wide distribution through out Bangladesh, India (Sikkim, The Himalayas, Assam), Myanmar, Sri Lanka, Singapore, Malaysia and China, whereas Lasia concinna is confined to Indonesia (Ara 2001, Hay 1988. In Bangladesh, L. spinosa is widely found in plain lands, marshy lands, hilly areas etc.…”

Karyotype and RAPD Analysis in Common and Rare Forms of <i>Lasia spinosa</i> (L.) Thwaites

et al. 2012

SummaryThe common Red flower Lasia spinosa (L.) and its rare Green flower form were investigated cytogenetically and at the molecular level by RAPD analysis to elucidate the taxonomic rank of the Green flower form. 2n 26 and 2n 28 chromosomes were found in the common Red flower form and the rare Green flower form, respectively. Two sub-metacentric chromosomes were present in the Green flower form. On the other hand, no sub-metacentric chromosome was found in the Red flower form. Two stain specific satellites were found in only the Red flower form. No CMA-band was found in the Red flower form. In contrast, 3 prominent CMA-positive bands were found in the Green flower form. The 2 forms showed distinct RAPD markers with 5 primer combinations. The 2 forms possessed characteristic karyotype and RAPD features, therefore do not support the view that the Green flower specimen may be considered a morphological form of Lasia spinosa.
