“…One of the most important active ingredients isolated from the seeds of this plant is a flavonoid called karanjin. This active ingredient is being used in the manufacturing of biopesticides and bioinsecticides in different names, one of them being Derisom (Majumdar, 2002;Majumdar, Pandya, Arora, & Dhara, 2004;Tamrakar, Yadav, Tiwari, Maurya, & Srivastava, 2008;Al Muqarrabun, Ahmat, Ruzaina, Ismail, & Sahidin, 2013). The seeds of Pongamia pinnata have an additional important benefit along with its possessing pesticidal properties, and the seeds are also being used for the synthesis of biodiesel along with the famous plant Jatropha.…”

Background: Adverse effects caused by the synthetic pesticides has forced scientists to develop an alternative against the synthetic pesticides. Therefore, it has come a boon to mankind in the form of neem tree having secondary metabolites showing pesticidal properties which is in use since many years. Like neem tree, there has been research done on karanja plant, and its secondary metabolite karanjin has been found to possess good pesticidal properties. Comet assay or alkaline single-cell gel electrophoresis (SCG) was performed in fish Cyprinus carpio after exposure to sub-lethal concentration (0.28 ppm) of karanjin. The assay was carried out in the gill, liver, kidney, and blood. The total DNA content in each tissue was also estimated using Nano Drop. Results: The present study clearly shows that though karanjin is a derived secondary metabolite from plant, it is capable of producing genotoxicity in common carp. As the days of sub-lethal exposure increased, all the four tissues showed decrease in total DNA content which was directly proportional to the formation of DNA comet tails. Conclusion: The use of any kind of plant metabolites in the agriculture and aquaculture farms should be monitored well.

“…The effect of karanjin reported here is in accordance with that reported earlier by Majumdar (2002) under laboratory conditions where karanjin inhibited nitrification by 62-75 % and mitigated N 2 O emission by 92-96 %. In another experiment conducted under laboratory incubation, nitrification inhibition by karanjin ranged between 9 and 76 %, remained high for a period of approximately 6 weeks and decreased with time (Majumdar et al 2004). Similarly, in this study, the plant product M. azedarach inhibited nitrification by 57 %.…”

“…The nitrification inhibition by karanjin was observed to remain high for a period of approximately 6 weeks, with inhibition ranging between 9 and 76 % for a range of soils studied (Majumdar et al 2004). Similarly, fruits of dharek (Melia azedarach) are poisonous to humans and these are chemically related to Azadirachtin, the primary insecticidal compound in the commercially important neem oil.…”

“…After 72 h, the precipitate was collected and crystallized in ethanol and its melting point was observed. It was re-crystallized a number of times in ethanol to yield the final product (Majumdar et al 2004). A solution of karanjin and dharek was prepared by dissolving crystals of karanjin and M. azedarach in acetone, and the solution was added to the soil containing DAP (200 mg kg -1 soil) at the rate of 20 % of applied N (Majumdar et al 2004).…”

“…An aqueous solution of diammonium phosphate [(NH 4 ) 2 HPO 4 ] i.e., DAP was applied as N source to all pots except control to supply 200 mg N kg -1 soil. A 200 mg l -1 solution of karanjin and M. azedarach was prepared by dissolving crystals of karanjin and dharek in acetone and the solution was added to the soil containing DAP (200 mg kg -1 soil) at the rate of 20 % of applied N (Majumdar et al 2004). A basal dose of 90 mg P 2 O 5 kg -1 soil as SSP and 60 mg K 2 O kg -1 soil as potassium sulfate was well mixed into the soil before sowing.…”

The aim of this study was to evaluate the relative performance of three nitrification inhibitors (NIs) viz. calcium carbide (CaC 2 ), and plant derivatives of Pongamia glabra Vent. ? -N and NO 3 --N were examined during the study. A second experiment was conducted in a glasshouse using pots to evaluate the response of wheat to these amendments. Results indicated that more than 92 % of the NH 4? initially present had disappeared from the mineral N pool by the end of incubation. Application of NIs i.e., CaC 2 , karanjin, and M. azedarach resulted in a significant reduction in the extent of NH 4? disappearance by 49, 32, and 13 %, respectively. Accumulation of NO 3 --N was much higher in N amended soil 57 % compared to 11 % in N ? CaC 2 , 13 % in N ? karanjin, and 18 % in N ? M. azedarach. Application of NIs significantly increased growth, yield, and N uptake of wheat. The apparent N recovery in N-treated plants was 20 % that was significantly increased to 38, 34, and 37 % with N ? CaC 2 , N ? karanjin, and N ? M. azedarach, respectively. Among the three NIs tested, CaC 2 and karanjin proved highly effective in inhibiting nitrification and retaining NH 4? -N in the mineral pool for a longer period.

Ungefähr zwei Prozent des Weltenergieverbrauchs werden zur Herstellung von Ammoniak aus Wasserstoff‐ und Stickstoffgas aufgewendet. Als Bestandteil von Düngemitteln zur Wachstumsförderung von Kulturpflanzen in der Intensivlandwirtschaft gelangt Ammoniak in riesigen Mengen in die Umwelt. Nur 30–50 % des eingesetzten Stickstoffs werden von den Nutzpflanzen aufgenommen, die übrigen 50–70 % gehen in biologische Prozesse ein, z. B. die Nitrifikation durch den Stoffwechsel von Bodenmikroben. Dies bewirkt ein Ungleichgewicht im globalen Stickstoffzyklus und höhere Emissionen von Distickstoffoxid (ein wirksames und bedeutendes Treibhausgas) sowie die Verunreinigung von Grund‐ und Oberflächenwasser durch Nitrat aus den stickstoffgedüngten Ackerböden. Dieser Aufsatz gibt einen kritischen Überblick über das aktuelle Wissen zu den an der Ammoniaknitrifikation beteiligten Bodenmikroben, den Strukturen und Mechanismen der zugehörigen Enzyme sowie sekundäre Pflanzenstoffe, die die Ammoniaknitrifizierung hemmen können.
