“…The lectin showed an IC50 of 1.17 ± 0.08, 0.58 ± 0.03, and 2.51 ± 0.03 mg/ml for those methods respectively. These results give support to reported studies that detected lectins with antioxidant potential in some leguminous seeds [35,46,47] and also to other reported antioxidant proteins from other plant family [48][49][50]. Though, antioxidant activity in protein possibly will not be ascribed to a single mechanism.…”

Objective: This study was carried out to purify and characterize a carbohydrate-binding and cell-agglutinating protein, lectin, from Pterocarpus osun seeds and also to evaluate its antioxidant and antibacterial potential. Methods: Isolation and purification of the lectin were done by ammonium sulphate precipitation and size exclusion chromatography on Sephadex G-100. Physicochemical properties of the lectin were determined and antioxidant activity was evaluated by DPPH radical scavenging, lipid peroxidation inhibition and ferric reducing antioxidant potential assay. A disc diffusion method was used for antibacterial effect. Results: Lectin was detected in the seeds and was able to agglutinate native and enzyme-treated rabbit erythrocytes but only enzyme-treated erythrocytes of human blood were agglutinated. Mannose, Maltose and α-methylmannoside inhibited the divalent cation-independent hemagglutinating activity, which was stable up to 60°C and at pH range of 3-13. It showed antioxidant activity with IC50 of 1.17 ± 0.08, 0.58 ± 0.03, and 2.51 ± 0.03 mg/ml for those methods respectively. No antibacterial activity was observed. Conclusion: Pterocarpus osun seeds lectin possess properties similar to other lectins from Dalbergieae tribe and its ability to scavenge free radical and inhibit lipid peroxidation show the presence of a valuable health promoting agent in the seeds.

“…(My67) are widely used and studied in Thailand. It is used as a food ingredient and for treating gynecological problems [ 42 ]. Pharmacological research has shown that this plant has multibioactivities including antilipidemic, choleretic, estrogenic, uterotrophic, anti-inflammatory, male fertility, vascular relaxation, nematocidal, prevention of hepatotoxicity, antioxidant, antiallergic, antibreast and antiuterine effects [ 43 – 47 ].…”

Myanmar has a rich pool of, but less known, medicinal plants with traditional knowledge. In this study, we aimed to investigate the inhibitory activity of traditional Myanmar medicinal plants against the type III secretion system (T3SS) of Salmonella enterica serovar Typhimurium UK-1 χ8956 and the intestinal disease-caused by microbes including S. enterica serovar Typhimurium UK-1 χ8956, Proteusbacillus vulgaris CPCC 160013, Escherichia coli CICC 10003, and Staphylococcus aureus ATCC 25923. The EtOH extracts of 93 samples were used to screen the inhibitory activities against the secretion of T3SS effector proteins SipA/B/C/D of S. enterica and the antibacterial activity against S. enterica, P. vulgaris, E. coli, and S. aureus. Out of 71 crude drugs traditionally used, 18 were proofed to be effective either on the growth inhibition of tested bacteria and/or as inhibitors for the T3SS. The EtOH extracts of five plants, Luvunga scandens (Roxb.) Buch.-Ham. ex Wight & Arn. (My7), Myrica nagi Thunb. (My11), Terminalia citrina Roxb. ex Fleming (My21), Thymus vulgaris L. (My49), and Cinnamomum bejolghota (Buch.-Ham.) Sweet (My104), showed potent inhibitory activities against the secretion of T3SS proteins SipA/B/C/D of S. enterica serovar Typhimurium UK-1 χ 8956. Mansonia gagei J.R.Drumm (My3) and Mesua ferrea (Roxb.) L. (My10) showed strong antibacterial activities against P. vulgaris and S. aureus. This study provided the first scientific evidence of T3SS prohibiting and antibacterial properties for the traditional knowledge in Myanmar of using plants as medicines for treating infections and gastrointestinal disease. Further researches are proposed to discover the active chemical compounds and mechanism of L. scandens (Roxb.) Buch.-Ham. ex Wight & Arn, M. nagi Thunb., T. citrina Roxb. ex Fleming, T. vulgaris L., and C. bejolghota (Buch.-Ham.) Sweet as antivirulence drugs and the potential of M. gagei J.R.Drumm and M. ferrea L. as new broad spectrum plant antibiotics.

“…Thus, CCK has been suggested to be a satiety peptide (Anika et al, 1981) and thus it is possible that any in in its luminal concentration as a result of any plant anti-nutrient like trypsin inhibitor(s), would lead to a reduced feed intake. Boonmee et al, (2011) found out biologically active proteins from Curcuma comosaRoxb rhizome from Thailand and considered as lectins (Pusztai., 1994).…”

The effects of raw and autoclaved Shoti (Curcuma zedoaria) meal on the growth and N utilization of growing broilers were determined. Shoti from Bangladesh Agricultural University campus was collected and sorted on the basis of white color of the rhizome. Then they were chopped into pieces, sun dried and pulverized in a flour mill. Aliquot samples were autoclaved at 1200C under 15 lb of pressure per square inch for 30 min. Autoclaved samples were stored in tightly lid contained for future use. 3 One hundred -day-old Cobb 500 broiler chicks were reared on the floor and a total of 24 growing broilers, 4 birds in each group were weighed on d 15 Two broilers were placed in each cage. There were a total of four experimental and two control (positive and negative Non-protein control) diets. Diets were fed ad libitum from day 15 to 33days. Body weight, feed intake, feed refusal and fecal weights were recorded every day. Cumulative feed efficiency per bird was calculated as the ratio of weight gained to feed consumed. Dry matter of excreta was determined from the last 10 d of feeding trial by drying aliquots of every day’s droppings by drying for 6 h at 1050C. On d 19, birds were bled to death. Immediately after slaughter, the carcasses were examined systematically. The chemical composition of Shoti meal showed that it is low in protein, fat and trace minerals and therefore mainly a source of energy. The bulk of the tuber (75 percent) consists of carbohydrates, made up of 10.6% fiber, and 64.9% nitrogen free extracts (NFE). A peculiarity of Curcuma rhizome meal contains high level of ash (9.9%) on DM basis. The results showed that at day 33, the weight of the broiler chicken fed shoti 100g, 200g, 300 g and 200g (autoclaved shoti meal)/ Kg diet was significantly different from the weight of the chicken fed on a maize-soybean diet. The birds given shoti meal consumed less feed than those provided with a maize diet. Feed efficiency or weight gain to feed ration over 19-d period was the poorest when fed 300 g Shoti/ Kg diet. Intake picked up when the shoti meal was incorporated after having been autoclaved and there was slight improvement in body weight gain as compared to that of other Shoti fed group. However, feed efficiency and body weight gain as % of initial weight remained significantly lower than the maize-soybean control. The inclusion of Shoti meal generally had an adverse effect on the apparent dry matter digestibility compared with the control diets. The group fed autoclaved shoti meal had a similar effect and the true N digestibility was the lowest when compared to those of control fed on maize-soybean meal. Thus, physical treatment like using autoclave, caused further reduction of digestibility of its N. Lipid digestibility was reduced by ingestion of shoti meal. Since the diets were isocaloric, after correction for the apparent endogenous lipid losses, which were obtained from the results of non-protein control feeding, the net faecal losses was around 66.2% of the ingested lipid against control diet fed birds.
