The present paper reports the phytochemical and micropropagation investigations of an undermined plant, Gymnema sylvestre. Gymnema sylvestre which has a place with the family Asclepiadaceae is a lasting moderate developing restorative woody climber generally called as “Gudmar“. There is a developing interest for leaves of G. sylvestre in the pharmaceutical exchange because of its utilization as a solution for diabetes and furthermore as a tonic of the nerves and as a diuretic. Proliferation of this plant is regularly hard and costly. In the present review the subjective examination affirmed the nearness of different phytochemicals like alkaloids, flavonoids, phenols, tannins, terpenoids and glycosides. Quantitative estimation of flavonoids and phenols was likewise completed and antimycotic potential further evaluated using standardized assays. In vitro proliferation is an option technique for spread of the undermined and imperiled plant which can help its preservation. The nodal explants were refined on MS medium containing diverse focus and mixes of development controllers like 6-benzylaminopurine (BAP) and indoleacetic corrosive (IAA). Different shoot buds were regener-ated effectively from the nodal explants which were proficiently established on 1⁄2 quality MS medium supplemented with IBA. The recovered plantlets were effectively exchanged to the glasshouse, acclimatized and exchanged to the field.

AbstractMerremia quinquefolia, is an important medicinal plant of the family Convolvulaceae known for its vasoconstrictor, uterotonic, neurohormonic, sympathicolytic and sedative effects. In the present investigation effect of cytokinins 6-benzylaminopurine (BAP), kinetin (Kn) and thidiazuron (TDZ), at concentrations 1.0, 2.0, 3.0, 4.0 and 5.0 mg·dm−3 on in vitro shoot multiplication from nodal explants of M. quinquefolia was evaluated. Bud breaking and emergence of shoots started within 10-15 days of inoculation in all media containing cytokinin. Murashige and Skoog (MS) medium supplemented with 4.0 mg·dm−3 BAP resulted in maximum number of shoots from single node within 45 days. In vitro raised shoots were successfully rooted on ½ mineral salts of MS medium with 3% sucrose supplemented with 2.0 mg·dm−3 indole-3-butyric acid (IBA). This is the first report on in vitro propagation of Merremia quinquefolia. This study can be useful for development of micropropagation protocols for related taxa.

A protocol for the regeneration of Gypsophila paniculata L. using nodal explants from 2-month-old field grown plants was established. The induction of multiple shoots was best obtained on Murashige and Skoog (MS) medium supplemented with 13.3 μM BA. Callus growth was observed on MS medium containing 44.3 μM BA. Calluses were transferred to MS medium supplemented with 2, 4-D (4.5, 13.5, 22.6 μM), NAA (5.3, 16.1, 26.8 μM) or BA (4.4, 13.3, 22.1 μM) for 2 months to induce shoot formation. After 6 weeks of initial culture, multiple shoots were regenerated from calluses cultured on MS medium supplemented with 13.3 μM BA. All regenerated shoots produced roots on 16.1 μM NAA containing MS medium within 4 weeks. Rooted plantlets were hardened and established in pots at 100% survival. For induction of in vitro flowering, regenerated shoots could be induced to flower efficiently when cultured on MS medium containing 13.3 μM BA and 50 g/l sucrose.

In vitro cultures were initiated from a single seed of Centaurea davidovii. Whole plantlets were regenerated and cultivated for several months on agar-solidified nutrient media differing by their composition: basal MS medium, MS medium supplemented with plant growth regulators, and liquid MS medium. Plantlets were ex vitro adapted and successfully acclimated to open-air conditions; flowering was observed in some individuals in the first summer, and mass flowering during the second summer. The contents of the total flavonoids and the total phenolic compounds were determined spectrophotometrically in the leaves of the in vitro plantlets cultured on different media, and then compared with those in the leaves of the wild plants and in the leaves of the acclimated plants of the field plot. The sesquiterpene lactone 8α-(5′-hydroxyangeloyl)-salonitenolide was determined by HPLC in leaf samples of C. davidovii wild plants, in vitro obtained plantlets and ex vitro acclimated plants in the greenhouse and on the experimental field plot. The composition of the nutrient medium influenced the contents of all studied bioactive substances. The highest concentrations of all tested secondary metabolites were detected in the leaves of the acclimated plants during mass flowering, the content of the lactone reaching 56.2 mg/g DW, which was several times more than in the other leaf samples. The obtained results revealed both the effectiveness of biotechnological methods for propagation and conservation of rare and endangered plant species, and the possibility to use C. davidovii plants ex vitro acclimated to field conditions as a source of secondary metabolites with potential biological activity.

Clerodendrum Phlomidis

Abstract Clerodendrum phlomidis L. f. is an important medicinal plant of the Lamiaceae family, particularly its roots, which are used for various therapeutic purposes in a pulverized form. The objective of this study was to develop a standard protocol for axillary shoot proliferation and rooting of C. phlomidis for its propagation and conservation. Nodal explants were inoculated on Murashige and Skoog (MS) medium that was supplemented with one of six cytokinins: 6-benzyladenine, kinetin, thidiazuron, N6-(2-isopentenyl) adenine (2iP), trans-zeatin (Zea) and meta-topolin. Callus induction, which was prolific at all concentrations, formed at the base of nodal explants and hindered shoot multiplication and elongation. To avoid or reduce callus formation with the objective of increasing shoot formation, the same six cytokinins were combined with 4 μM 2,3,5-tri-iodobenzoic acid (TIBA) alone or in combination with 270 μM adenine sulphate (AdS). Nodal explants that were cultured on the medium supplemented with 9.12 μM Zea, 4 μM TIBA and 270 μM AdS produced significantly more and longer shoots than on medium without TIBA and AdS. Half-strength MS medium supplemented with 8.05 μM α-naphthaleneacetic acid was the best medium for root formation. Most (75%) in vitro rooted plantlets were successfully acclimatized under natural conditions.

Kankakee mallow is an endangered herbaceous perennial that is indigenous to Kankakee County, Illinois. Stock plants were from seeds pretreated in 82°C water prior to greenhouse germination and growth. Nodal explants were disinfested and placed in vitro onto agar-solidified MS medium containing 0, 0.1, 1.0, 5.0, or 10.0 μM BA and 1.0 μM IBA. Axillary shoots grew and elongated best when the medium contained no cytokinin. BA tended to result in a rosette pattern of leaves. Within hours of placing the original explants in vitro and shortly after subsequent transfers were made (even when there was no cutting) a bright pink exudate appeared in the medium. The most vigorous cultures tended to form the most exudate. Microshoots were placed in a high humidity container in vermiculite wetted with water. Rooting was 50% without auxin. Plants were transplanted into pots containing peat-lite medium and successfully acclimatized to the greenhouse.
