“…In the present study, karanja cake was tested for its use as proteinrich animal feed. The karanja cake as such is unpalatable and toxic because of the presence of furanoflavones like karanjin, pongamol, pongapin, pongaglabron, kanjone and isopongaflavone lanceolatin B (Rangaswami and Seshadri, 1940;Roy et al, 1977). The karanja seeds contain 0.57% to 1.7% karanjin, 0.25% to 1.3% pongamol and 0.08% to 0.13% trypsin inhibitor activity (Dineshkumar et al, 2011).…”

The protein-rich non-conventional detoxified karanja cake (dKC) can be used in place of conventional protein supplements like soybean meal (SBM), groundnut meal, etc. in livestock feed. The present study was conducted to assess the effect of two levels of dKC by replacing SBM on testicular architecture, semen quality and expressions of mRNAs encoding luteinizing hormone receptor (LHR) and insulin-like growth factor (IGF-I) in testes of ram lambs. Eighteen ram lambs were randomly divided into three groups (n 5 6) and fed different levels (%) of karanja cake (0% replacement -control; 50% replacement -dKC-50 and 75% replacement -dKC-75) for 140 days. After 120 days of feeding, the semen from the animals was collected and analysed. The testes samples were collected on day 140 of feeding for transcripts expression studies. The dKC-50 group had no change in BW, whereas dKC-75 group showed decreased ( P , 0.05) BW as compared with control. The number of animals ejaculated semen in dKC-75 group was lower ( P , 0.05) than the control group. A reduction ( P , 0.05) in LHR expression in dKC-75 was observed, whereas a reduction in IGF-I expression ( P , 0.05) was observed in dKC-50 and dKC-75 as compared with control group. The study reveals that in ram lambs, long-term feeding of dKC at 50% replacement of SBM may not affect BW. However, long-term feeding of dKC as a replacement of SBM may affect testicular function.Keywords: karanja cake, ram lambs, semen quality, IGF-I, LHR ImplicationsThe demand for animal feed with ever increasing animal population necessitates the use of unconventional feed. One such feed is protein-rich karanja cake. The detoxified karanja cake was fed to ram lambs and its effect on reproductive performance was studied. A high level of protein replacement with karanja cake decreased testicular function and sperm concentration while feeding a lower level did not influence these factors by 140 days.

“…Six peaks were identified by comparing with reference standards as pachycarin A (18), 3',4'-dimethoxy [2",3":7,8]furanoflavone (25), karanjin (29), pongaglabol (39), karanjachromene (40) and isoderricin A (41). All reference compounds exhibited [M+H] + ions of sufficient abundance in MS.…”

“…Thus, furanoflavones were the major flavonoid chemical types in FC, while for MP the major types were chalcones and pyranoflavones. There are 11 common peaks, which are (−)-maackiain (1), 7,4'-dihydroxyisoflavone (3), 7-hydroxy-4'-methoxyisoflavone (12), 7-hydroxy-4'-methoxyisoflavone (21), lanceolatin B (23), karanjin (29), isopongaflavone (30), 7-methoxyl-8-(3''-hydroxy-3''-methyl-1''-butenyl)-flavone (33), 4',7-dimethoxy-8-prenylisoflavone (37), 6'',6''-dimethylpyrano[2'',3'':7,8]flavone (38) and karanjachromene (40), between FC and MP.…”

“…Our previous report showed that karanjin (29) was the major common peak between FC and MP, and pachycarin A (18), 3',4'-dimethoxy[2",3":7,8]furanoflavone (25), karanjachromene (40) and isoderricin A (41) can be used to differentiate between FC and MP samples [15]. However, this study indicated there were 26 compounds which were detected in FC and were not in MP, and there were four chemicals that existed in MP but not in FC (Table 1 and Figure 2C).…”

Characterization of Flavonoids in the Ethomedicine Fordiae Cauliflorae Radix and Its Adulterant Millettiae Pulchrae Radix by HPLC-DAD-ESI-IT-TOF-MSn

Fordiae Cauliflorae Radix (FC, the root of Fordia cauliflora Hemsl) and Millettiae Pulchrae Radix [MP, the root of Millettia pulchra (Benth.) Kurz var. laxior (Dunn) Z. Wei], which go under the same local name of "Daluosan", have long been used in Southern China for the treatment of stroke, paralysis, dementia in children, Alzheimer's disease and other diseases. The same local name and similar functions always confuse users. To further utilize these two ethnodrugs and identify them unambiguously, an HPLC-DAD-ESI-IT-TOF-MS n method was developed to separate and characterize the flavonoids in FC and MP. A total of 41 flavonoids were detected, of which six compounds were identified by comparing their retention time and MS data with those of the reference standards, and the others were tentatively identified based on their tandem mass spectrometry data obtained in the positive ion detection mode. Nineteen of these characterized compounds are reported from these two plants for the first time.

Insect pests are considered the major hurdle in enhancing the production and productivity of any farming system. The use of conventional synthetic pesticides has led to the emergence of pesticide-resistant insects, environmental pollution, and negative effects on natural enemies, which have caused an ecological imbalance of the predator-prey ratio and human health hazards; therefore, eco-friendly alternative strategies are required. The plant kingdom, a rich repertoire of secondary metabolites, can be tapped as an alternative for insect pest management strategies. A number of plants have been documented to have insecticidal properties against various orders of insects in vitro by acting as antifeedants, repellents, sterilant and oviposition deterrents, etc. However, only a few plant compounds are applicable at the fi eld level or presently commercialised. Here, we have provided an overview of the broad-spectrum insecticidal activity of plant compounds from neem, Annona , Pongamia , and Jatropha . Additionally, the impact of medicinal plants, herbs, spices, and essential oils has been reviewed briefl y.
