Cellular localisation of the anti-cancer drug camptothecin in Camptotheca acuminata Decne (Nyssaceae).
In Camptotheca acuminata, we studied the cellular sites of accumulation of the alkaloid camptothecin (CPT), in both plants grown in the field and those grown in a greenhouse, subjecting the latter to stress (i.e., draught, nutritional deficit, and pruning). Fresh sections of the leaf, stem, and root were analysed for the presence of CPT by examining the autofluorescence that the CPT molecule em...
متن کاملEvaluation of antimicrobial activity of endophytic fungi from Camptotheca acuminata (Nyssaceae).
Agricultural research of plant-derived endophytic fungi has grown in recent decades. We isolated 26 endophytic fungi from the leaves, stems and fruits of "the tree of life", Camptotheca acuminata, and tested them for antimicrobial activities based on growth inhibition measurements in a modified agar diffusion method. Fermentation broths from most of the isolates exhibited antifungal activity an...
متن کاملUltrasonic Assisted-Reflux Synergistic Extraction of Camptothecin and Betulinic Acid from Camptotheca acuminata Decne. Fruits.
A novel and efficient ultrasonic assisted-reflux synergistic extraction (UARSE) method for extracting camptothecin (CPT) and betulinic acid (BA) from Camptotheca acuminata Decne. fruits has been developed in this study. The advantages of the ultrasonic and reflux extraction methods have been combined in the UARSE method and used to extract CPT and BA for the first time. The parameters influenci...
متن کاملMICROPROPAGATION OF Bauhinia acuminata L
Seeds of Bauhinia acuminata L. were used as an experimental material for micropropagation. The effect of growth regulators concentrations on morphogenetic development was studied. Seeds were germinated on MS medium supplemented with GA3 (0.10, 1.0 and 2.0 mgL -1 ) and without GA3. Satisfactory germination was observed at media with 1.0 mgL -l GA3. Subsequent propagation from plantlet was perfor...
متن کاملMicropropagation and antimicrobial activity of Operculina turpethum (syn. Ipomoea turpethum), an endangered medicinal plant
Operculina turpethum (syn. Ipomoea turpethum) a plant in the morning glory family is an endangered medicinal plant of Bangladesh and its neighboring countries. An efficient micropropagation protocol was established for this plant through nodal segment culture as well as antimicrobial activity of the leaves was also evaluated. For micropropagation, nodal segments with axillary buds of field grow...
