Duration from sowing to flowering is the most important trait influencing adaptation in pigeon pea (Cajanus cajan), but the inheritance of this trait has not been elucidated clearly. Crosses were made between two early (60 to 70d) and one late (160 to 170d) flowering pigeonpea genotype and F1, F2 and BC1 populations produced. These populations, comprising 60 to 100 parents, 30 F1, 400F2 and 40 to 50 BC1 plants, were grown under natural (mean13.4 hd-1) and artificially extended (to 15 hd-1) daylength and duration from sowing to first flowering recorded. Genetic analysis of the segregation ratios, supported by Chi-square tests, indicated that the duration from sowing to flowering in each of t…
Enzyme pretreatment and negative pressure cavitation extraction of genistein and apigenin from the roots of pigeon pea [Cajanus cajan (L.) Millsp.] a…

Abstract An enzyme pretreatment and negative-pressure cavitation extraction (E-NPCE) method was investigated for extraction genistein and apigenin from pigeon pea roots. The important parameters involved in E-NPCE process were optimized by single-factor experiments and then critical parameters were investigated by a 2 3 full factorial central composite design (CCD) to optimize extract conditions. Under optimal conditions, the yields of genistein and apigenin were 0.628 mg/g and 0.359 mg/g, which represented an increase of 44.70% and 53.05%, respectively, compared to standard NPCE. Furthermore, from DPPH scavenging activity test the extract of E-NPCE showed better antioxidant activity than t…

Abstract A fungal endophyte MD89 with obvious antioxidant activities was isolated from pigeon pea and identified as Chaetomium globosum by ITS sequence. Different fractions from MD89 culture were compared and evaluated by total phenol (TP) content, total flavonoid (TFL) content, DPPH radical scavenging, reducing power and lipid peroxidation assays, respectively. Results showed that EtOAc extracts had high content of TP and TFL, and strong antioxidant activities (IC 50 value was 6.87, 15.19, 16.78 μg/mL, respectively). Furthermore, the EtOAc extracts were analyzed by LC–MS/MS and a good antioxidant compound, apigenin, was found. The activities of superoxide dismutase (SOD) and glutathione re…
