Hepatoprotective Potential of Tecomella undulata Bark on Paracetamol and CCL4 Induced Hepatotoxicity in Rats: Invitro Analysis

In this study the T. undulata bark was tested for its hepatoprotection against paracetamol (PCM) induced hepatic damage and Carbon tetra chloride (CCl4) induced hepatotoxicity. The Invitro study was performed on HepG2 cell line .The Levels of serum marker enzymes i.e. AST, ALT (aminotransferases), ALP (alkaline phosphatase), GSH (reduced glutathione) and MDA (Malondialdehyde) in 70% Ethanol treated rats were monitored, respectively. The 70% Ethanol extract gave promising results as studied in detail. The Present study showed that the 70 % ethanolic extract of bark of T.undulata apparently revive the physiological integrity of hepatocytes. Thus the present study demonstrated the Hepatoprotective property of Tecomella undulate Bark.

Somatic Embryogenesis; A Highly Promising Technique for Conservation of Tecomella Undulata – A Multi-Purpose Tree on the Verge of Extinction

Over-exploitation of trees by increasing human population has put an enormous pressure especially on those species having slow growth and low reproduction rate. Desert teak (Tecomella undulata (Sm.) Seem) a multipurpose agroforestry tree of arid zone has fallen on the verge of extinction in Iran due to lack of efficient seed reproduction. Inherent low adventitious rooting has caused vegetative mass macro- and micropropagation (organogenesis pathway) of this tree to be unsuccessful. Somatic embryogenesis (SE) pathway by production of bipolar embryo capable of development into a complete plantlet can solve the problem. Hence, a research was carried out to evaluate the feasibility of in vitro regeneration of the tree by SE. Ovary extracted from un-pollinated flower was cultured in the media supplemented with different auxins and cytokinins (CKs). The results showed α-naphthalene acetic acid (NAA) was superior in induction of embryogenic callus (EC). NAA ranging 5.4–21.5 µM could induce the highest ECs which exhibited developing pro-embryogenic masses (PEMs) and globular somatic embryos. Both CKs, thidiazuron (TDZ) and N6-benzyladenine (BA), though induced good callogenesis at low concentrations but the formed calli were non-embryogenic. Proliferation of NAA–induced ECs revealed that hormone-free medium is the best choice. However, the media containing 40.5 and 54 µM NAA alone could also induce somatic embryos along with callus proliferation. Effort for maturation of the obtained globular, hear-shaped and torpedo embryos did not yield satisfactory results. Low BA-contained medium led to secondary SE. More research is expected to be undertaken to optimize SE in desert teak.

Some noteworthy plants record to the flora of Yavatmal district, Maharashtra, India

The present paper deals with the addition of 05 new plant species i.e. Tephrosia pumila, Striga asiatica, Tecomella undulata, Orobanche cernua and Sauromatum venosum belonging to 05 different families; from this 01 additional family i.e. Orobanchaceae is reported for the first time to the flora of Yavatmal district. This study provides the correct and updated detail information about morphology, phenology and occurrence of these new additional plant species for the future work.
