Breadfruit (Artocarpus altilis (Park.) Fosberg) is a woody tropical tree. In addition to the nutritious value, breadfruit is also a precious medicinal source, because every part of it contains many natural compounds with biological activity. With the aim of providing a pharmaceutical source cond food with high yield, as well as the short harvert time, we examined the effects of the concentration of benzyl adenine (BA) on the in vitro culture of young female breadfruit flowers. The results showed that in the first phase of the culture, the concentration of 5 mg/L BA stimulated an increase in size of each female flowers, especially in the calyx. The increasing concentration of 10 mg/L BA stimulated the formation of callus in the calyx of each female flowers. Roles of respiration rate and endogenus hormones were discussed to understand the physiological changes in the in vitro culture of young female breadfruit flowers.

Artocarpus Altilis

Under the influence of plant hormones, after 8 weeks of in vitro culture, the growth of breadfruit shoot (Artocarpus altilis (Park.) Fosberg) was very different. With shoots that were cultured on 1 mg/L BA medium after 10 days of being transferred to ½ MS supplemented with 10 mg/L BA medium, the percentage of shoot development was the highest (86.8 %), and the secretion of phenolic compounds or forming callus were not observed. On the ½ MS supplemented with 12 mg/L BA medium, shoots growed strongly and healthily but the secretion of phenolic compounds and the forming of callus affected the ability of the shoot development. On the ½ MS supplemented with 0.45 mg/L BA, 0.6 mg/L Kinetin (Kin) medium and on the ½ MS supplemented with 0.45 mg/L BA, 0.6 mg/L Kin, 0.35 mg/L GA3 medium, the percentage of shoot developed were lower than those on the ½ MS supplemented with 10 mg/L medium. The addition of 0.35 mg/L GA3 in the culture medium help to appear the lateral more than the remaining experiments. Roles of respiration rate and endogenous hormones were discussed to understand the physiological changes in the in vitro culture shoots breadfruit.

A conventional condensation reaction of an aromatic aldehyde, Benzaldehyde with seven different aromatic amines viz. Aniline, 2-Choro-aniline, 3-Choro-aniline, 4-Choro-aniline, 2-Nitro-aniline, 3-Nitro-aniline and 4-Nitro-aniline and reacted efficiently to synthesize a series of Aldmines, I to VII, in moderate to high yield and high purity. The reaction was monitored and the products were analyzed by employing the TLC technique. All the products obtained were characterized by their colour, physical constant, TLC, elemental analysis and spectral (UV-Vis and FTIR) method. The synthesized Aldimines were subjected to in vitro biological activity.

Bulbous Plant

Leucojum aestivum is a native, protected ornamental and medicinal plant in Hungary and in Ukraine too. The aim of our work was to establish in vitro cultures of this bulbous plant. Prior to surface sterilisation the old leaves and roots were dissected from the bulbs and they were stored in a refrigerator (2-3°C) for different periods (1 week for the first starting experiment and 5 weeks for the second one). After sterilisation, bulbs, bulb scales and leaves of the bulbs were placed on Murashige and Skoog's (1962) medium with 1 mg/1 benzyl-adenine (BA) and 0,1 mg/1 naphthalene acetic acid (NAA). At the first starting experiment 81,3%, and at the second one 92,3% of the explants turned to be sterile. Bulblets and roots were developed on the explants in the case of using bulb plates together with bulb scales and leaves as inoculua. The best result was achieved after 5 weeks chilling and it was possible to gain little bulbs from the bulb leaves too.

ABSTRACT A number of corticotrophin analogues have been prepared, some of which potentiate the biological activity of the untreated hormone in vitro. The free amino groups of corticotrophin appear to be essential not only for hormonal activity, but also for the interaction of the analogues with the tissue corticotrophin inactivating system which is assumed to account for the potentiating effect.
