Justicia adhatoda L. (Family: Acanthaceae) has been exploited in India because of rich source of polyphenolic compounds which are used in stress related therapy. The Pharmacognostical study includes preliminary phytochemical screening of alkaloids, phenols, flavonoids and saponins which were confirmed in both in vivo grown garden plants as well as in vitro generated plantlets of J adhatoda. Explants inoculated on MS medium supplemented with different combination of auxins and cytokinins were successfully employed; combination of NAA (0.5µg/ml) and BA (2.0µg/ml) for nodal explants was found to be effective concentration to obtain plant regenerants from nodal explants. Rooting in the regenerants was also successfully initiated on transfer into half MS basal medium, supplemented with IBA (1.0 µg/ml). Addition of ADS (0.5µg/ml) in the above combinations of phytohormones induced multiple shoot from nodal explants. After hardening for 35 days in highly humidified acclimatized room, nearly 70 % of rooted plantlets survived in the field. Phytochemical screening revealed the presence of alkaloids, phenolic compounds, flavonoids and saponins in the methanol and aqueous extracts of both in vivo grown garden plants and in vitro genereated plantlet samples. Further analysis of the extracts on Thin Layer Chromatography and spectrophotometric estimation confirmed the presence of vasicine alkaloids in these extract samples with marked difference in quantity.

In this study, different concentrations of 6-benzyladenine (BA) on in vitro shoot and inflorescence inductions of P. lanceolata were investigated. The in vivo and in vitro floral characteristics of this plant were also compared. Nodal explants of P. lanceolata were cultured vertically with the cut ends inserted into semi-solid Murashige and Skoog (MS) medium supplemented with 0, 0.5, 1, 2, 4, and 8 mg L–1 BA. The results showed that the explants formed the highest numbers of shoots even when cultured in MS basal medium without any addition of BA, while the shoots formed in the explants cultured in MS medium supplemented with 1 mg L–1 BA were the longest. No inflorescence was found in the shoots cultured in MS medium supplemented with 8 mg L–1 BA, while the highest percentage of inflorescence induction was found in the shoots cultured in the medium supplemented with 0.5 mg L–1 BA. The apperances of in vivo and in vitro flowers of P. lanceolata were the same in many aspects except that the number of flower/inflorescence formed was different. In addition, water accumulation was observed only inside the in vitro flowers. Water deposit in the long tubular structure of P. lanceolata flower could cause anther injury, suggesting that flowers developed in vitro may not always produce pollen.

Holoptelea integrifolia Roxb. Planch (HI) has been used to treat various ailments including obesity, osteoarthritis, arthritis, inflammation, anemia, diabetes etc. To review the major phytochemicals and medicinal properties of HI, exhaustive bibliographic research was designed by means of various scientific search engines and databases. Only 12 phytochemicals have been reported including biologically active compounds like betulin, betulinic acid, epifriedlin, octacosanol, Friedlin, Holoptelin-A and Holoptelin-B. Analytical methods including the Thin Layer Chromatography (TLC), High-Performance Thin Layer Chromatography (HPTLC), High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography With Mass Spectral (LC-MS) analysis have been used to analyze the HI. From medicinal potency point of view, these phytochemicals have a wide range of pharmacological activities such as antioxidant, antibacterial, anti-inflammatory, and anti-tumor. In the current review, it has been noticed that the mechanism of action of HI with biomolecules has not been fully explored. Pharmacology and toxicological studies are very few. This seems a huge literature gap to be fulfilled through the detailed in-vivo and in-vitro studies.

In Vitro Shoot Regeneration

Efforts have been made to establish a protocol for direct multiple shoot regeneration from both in vitro grown seedlings and mature plants of Citrus macroptera. Both nodal and shoot tip explants taken from in vitro grown seedlings were cultured in MS supplemented with different concentrations of BAP and Kn either singly or in combinations. Both these explants are capable to regenerate and produce in vitro multiple shoots. Maximum number of shoots were obtained from nodal explants in MS supplemented with 1.0 mg/l BAP. BAP alone was found superior to Kn. On the other hand, only nodal explants from mature plants were used and 1.0 mg/1 BAP was also found best suitable for shoot induction and multiplication. Ex vitro rooting in pot soil (mixed with biogas slurry derived from cow-dung) was most successful compared to in vitro rooting in half strength of MS supplemented with different concentrations of NAA and IBA. Key words: In vitro, Shoot regeneration, Citrus macroptera D.O.I. 10.3329/ptcb.v18i1.3246 Plant Tissue Cult. & Biotech. 18(1): 17-24, 2008 (June)

Shoot Initiation

High frequency plant regeneration protocol has been standardized from banana cultivar Musa paradisiaca cv. Karibale Monthan, an endemic cultivar of Malnad region of Karnataka. The fruits are used as glomerular protective to solve kidney problems. To minimize the microbial contamination and to promote healthy growth, explants were treated with 70 % absolute alcohol for 6 min, 0.1 % Mercuric chloride for 10 min and 0.2 % for 10 min, 1 % Sodium hypochlorite for 15 min, 0.1 % Cefotaxime for 5 min and 0.05 % Gentamicin for 5 min. The high frequency shoot initiation (93.33 %) was recorded at 5 mg/l BAP. The synergetic effect of BAP (4 to 6 mg/l), TDZ (0.1 to 1.2 mg/l) and coconut water (0.1 to 0.9 ml/l) induced multiple shoot buds and it was optimized at the concentration of 5 mg/l BAP, 0.5 mg/l TDZ and 0.5 ml/l coconut water with 15.90 ± 1.66 frequency of shoots per propagule. Supplementation of 1.0 mg/l IBA induced 5.33 ± 1.21 numbers of roots with a mean root length of 7.50 ± 1.87 roots. The 99% of plantlets with distinct roots and shoots were successfully acclimatized in the green house and transferred to the field to evaluate the agro-morphological variations. The weight of the bunch (kg), number of hands in a bunch, number of fingers in a hand, length of the finger (cm), girth of the finger (cm) and girth of the pseudostem (cm) exhibited by in vitro plants were higher than the in vivo plants.Int J Appl Sci Biotechnol, Vol 3(2): 202-209 DOI: http://dx.doi.org/10.3126/ijasbt.v3i2.12536

Objective: A normal-phase high-performance thin-layer chromatography (HPTLC) method has been developed and validated for estimation and quantitation of beta-sitosterol from the methanolic fraction of different plant parts of two medicinally important plants viz. Merremia aegyptia and Merremia dissecta. These plants have been reported to possess antimicrobial, antioxidant, and anti-inflammatory activities. Methods: Chromatographic separation of beta-sitosterol from the methanolic extracts of plant parts of M. aegyptia and M. dissecta was performed on TLC aluminum plates pre-coated with silica gel 60F254 using a suitable mobile phase. The densitometric scanning was done after derivatization at ????-580 nm for ????-sitosterol. Result: Only M. dissecta leaf sample was reported to contain ????-sitosterol (4.6 ng/μl), whereas other samples such as seed, stem, and callus extracts of M. aegyptia and M. dissecta did not showed its presence. Conclusion: The developed HPTLC method is simple, rapid, and precise and can be used for routine analysis and quantification of ????-sitosterol and other useful plant bioactives that are phytopharmaceutically important.

An efficient mass propagation method for Feronia limonia was developed from excised shoot tips and nodal explants of in vitro grown seedlings. Explants were cultured on MS medium with different conc. of NAA, Kn, IAA and BAP singly or in combinations. Highest number of micro shoots and better plant growth were obtained from these two explants on MS medium supplemented with 0.2 mg/l BAP alone. The regenerated shoots were successfully rooted on MS medium supplemented with 0.5 mg/l NAA. The in vitro raised plantlets were successfully established in soil following the formation of roots with 100% survivability under ex vitro condition.

Abstract Binding of 63Ni(Il) to ultrafiltrable constituents of rabbit serum was studied (a) after in vitro incubation (2 h, 37 °C) of rabbit serum with 63NiCl2 (10-100 µmol/liter), and (b) at intervals (0.25-2 h) after in vivo administration of 63NiCl2 (40-160 µmol/kg body wt, i.v.). Serum ultrafiltrates were fractionated by thin-layer chromatography, and the separated compounds made visible by autoradiography and by ninhydrin staining. Several (≃5) ultrafiltrable 63Ni-complexes were demonstrable as distinct radiodense 63Ni-bands with chromatographic mobilities corresponding to those of ninhydrin-positive bands. Unbound 63Ni(II) was not detected in serum ultrafiltrates in either the in vitro or in vivo experiments. In sera (n = 10) incubated in vitro with 63Ni(II) (10 µmol/ liter), the mean percentage of ultrafiltrable 63Ni was 36% (range = 33-38) of total serum 63Ni. In contrast, in sera (n = 10) obtained 2 h after i.v. injection of 63Ni(II) (40 µmol/kg), the mean concentration of total serum 63Ni was 10.8 µmol/liter (range = 6-14), and the mean percentage of ultrafiltrable 63Ni was 15% (range = 9-21) of total serum 63Ni. The disparity between the percentages of ultrafiltrable 63Ni obtained in vitro and in vivo was obviated when the in vivo experiments were performed in rabbits bilaterally nephrectomized, with ligated common bile ducts. This investigation confirms the existence of several nickel receptors in serum ultrafiltrates and substantiates the role of ultrafiltrable complexes in the excretion of nickel.

Fatty Acid Compositions

Phosphatidylethanolamine from mitochondria and microsomes of guinea pig liver was separated by thin-layer chromatography into eight different classes differing in degree of unsaturation. The fatty acid compositions and molar proportions of each class isolated from microsomes were very similar to the corresponding class in mitochondria. In both organelles about half of the total was dienoic species while tetraenes comprised approximately 20%. Stearic acid was the major saturated fatty acid and in each membrane a greater selectivity for stearate over palmitate was found in each sub-class of phosphatidylethanolamine, when compared with the corresponding class of phosphatidylcholine.Following the intraperitoneal injection of [2-3H]glycerol, the labelling of each molecular class of phosphatidylethanolamine showed very similar progressions in microsomes and mitochondria over a 3 h interval. In both organelles the highest relative specific activity was attained by penta-plus hexaenoic classes, while the large dienoic class had the lowest relative activity, which, however, increased with time. Analysis of the dienoic class of phosphatidylethanolamine from whole liver showed it to be constituted by a rapidly turning over palmitoyl–linoleoyl fraction and a slowly labelled stearoyl–linoleoyl fraction, a pattern also exhibited by dienoic phosphatidylcholines.The similarities in profile of molecular classes of phosphatidylethanolamine and in the kinetics of labelling in vivo point to a close metabolic relation between the lipids of both organelles, suggestive of a transfer of different molecular classes at comparable rates from the endoplasmic reticulum, the site of synthesis, to the mitochondria. This is consistent with numerous other studies in vitro that have demonstrated inter-organelle exchange of lipids.
