The nutrient digestibility, nitrogen balance and in vivo metabolizable energy supply of Mucuna pruriens whole pods fed to growing Pelibuey lambs was investigated. Eight Pelibuey sheep housed in metabolic crates were fed increasing levels of Mucuna pruriens pods: 0 (control), 100 (Mucuna100), 200 (Mucuna200) and 300 (Mucuna300) g/kg dry matter. A quadratic (p<0.002) effect was observed for dry matter (DM), neutral detergent fibre (aNDF), nitrogen (N) and gross energy (GE) intakes with higher intakes in the Mucuna100 and Mucuna200 treatments. Increasing M. pruriens in the diets had no effect (p>0.05) on DM and GE apparent digestibility (p<0.05). A linear reduction in N digestibility and N retention was observed with increasing mucuna pod level. This effect was accompanied by a quadratic effect (p<0.05) on fecal-N and N-balance which were higher in the Mucuna100 and Mucuna200 treatments. Urine-N excretion, GE retention and dietary estimated nutrient supply (metabolizable protein and metabolizable energy) were not affected (p>0.05). DM, N and GE apparent digestibility coefficient of M. pruriens whole pods obtained through multiple regression equations were 0.692, 0.457, 0.654 respectively. In vivo DE and ME content of mucuna whole pod were estimated in 11.0 and 9.7 MJ/kg DM. It was concluded that whole pods from M. pruriens did not affect nutrient utilization when included in an mixed diet up to 200 g/kg DM. This is the first in vivo estimation of mucuna whole pod ME value for ruminants.

본 연구에서는 벨벳콩(Mucuna pruriens, M. pruriens) 추출물을 활용하여 천연소재 기반 항산화 기능성 화장품 소재로서의 활용가치를 검증하고자 하였다. 벨벳콩을 물과 70% 에탄올, 70% 아세톤을 용매로 하여 추출, 농축, 동결건조한 다음 각각의 분말화된 벨벳콩 열수 추출물(MW), 벨벳콩 70% ethanol 추출물(ME), 벨벳콩 70% acetone 추출물(MA) 시료를 확보하였다. MW, ME, MA를 활용하여 DPPH 라디칼 소거 활성, ABTS⁺ 라디칼소거 활성, SOD 유사 활성, 환원력, 총 페놀 및 플라보노이드 함량 분석을 통해 항산화 활성을 분석한 결과, 모두 우수한 항산화 효능을 나타내었다. 따라서 벨벳콩 추출물은 항산화 관련 기능성 화장품 천연소재로서의 활용 가능성이 높을 것으로 사료된다.

본 연구에서는 재활용 플라스틱 펠렛과 벨벳콩(Mucuna pruriens) 추출물의 항산화 효능 안정도에 대한 상관관계를 검증하였다. 재활용 플라스틱 펠렛을 벨벳콩 추출물에 침지 시킨 다음 다양한 온도 조건에서 30일간 보관한 후 DPPH radical 및 ABTS⁺ radical 소거능, SOD 유사 활성, 총 페놀 및 플라보노이드 함량 분석을 실시하였다. 기존 효능에 대비하여 DPPH radical 소거능은 ECOTRIA, PCR-PP 펠렛에서 30% 미만의 활성변화를 나타내었으며, Grico 펠렛에서 46.06%의 가장 큰 활성 감소가 확인되었다. ABTS⁺ radical 소거능 측정결과, 모든 펠렛에서 5% 미만의 효능 변화가 확인되었다. SOD 유사 활성을 측정한 결과, 모두 30% 이상의 활성 감소를 나타내었으며, 총 페놀 및 플라보노이드 함량 측정 결과, 모든 펠렛에서 기존 함량 대비 감소하는 경향을 나타내었다. 이를 통해 재활용 플라스틱 펠렛에 의한 벨벳콩 추출물의 생리활성 감소 및 변화를 확인하였으며, 본 연구 결과를 토대로 재활용 플라스틱 펠렛은 벨벳콩 추출물이 지닌 기존 효능 및 활성의 안정도에 영향을 미치는 것으로 판단된다.

The methanolic extract of natural roots of Mucuna pruriens was screened for hepatoprotective and antioxidant effects in carbon tetrachloride ($CCl_4$) induced hepatotoxicity in Albino rats. The degree of protection was measured by estimating biochemical parameters like serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, total protein and level of serum bilirubin (both total and direct). The extract also reduced $CCl_4$ induced lipid peroxidation both in-vitro and in-vivo. Hepatoprotective activity of methanolic extract at dose 300 mg/kg body weight, i.p., was comparable with standard drug Silymarin (25 mg/kg, i.p.). Furthermore, histopathological experiments were also carried out to support the study.

The study aim is to investigate the free radicals scavenging and spermatogenic potentials, as well as to analyze any reproductive toxicity of ethanolic extract of Mucuna prureins (M. pruriens) Linn. in spermatozoa, under different dosages in normal male rat. Normal rats were randomly selected and suspension of the extract was administered orally at the dosages of 150, 200 and 250 mg/kg body weight of the different groups of male rats (n=6) once in a day for 60 days and grouped as group II, III and IV respectively. Saline treated rats served as control -group I. On the $60^{th}$ day the animals were sacrificed and the epididymal sperm were subjected to various analyses like level of ROS production, LPO, enzymatic and non enzymatic antioxidant, morphology, morphometry, chromosomal integrity and DNA damage. Results showed significant reduction in ROS production and peroxidation and significant increase in both enzymic and non-enzymic antioxidants in all concentration treated groups when compared with control. Results from all the drug treated groups showed good sperm morphology, increased sperm count and motility. There was no DNA damage and showed normal chromosomal integrity even in 250 mg/kg dose. When compared with control all the three extract treated groups showed increased ROS scavenging activity. However, group II (200 mg/kg) showed significant changes in all the parameters. From the present study it was confirmed that the M. pruriens has potential to improve the sperm qualitatively and quantitatively through scavenging the excess ROS with any adverse side effects. These observations suggest that ethanolic seed extract of M. pruriens may serve as anti-oxidant that can exploit to treat the oxidative stress mediated male factor infertility.

Objective: Examine the effects of supplementing bahiagrass hay (BG) with potentially anthelmintic quantities of hays of perennial peanut (PEA) or sericea lespedeza (LES) or seeds of velvet bean (Mucuna pruriens L.; MUC) or papaya (PAP) on the intake and nutritive value (Experiment 1), and the performance and parasite burden (Experiment 2) of goats. Methods: In Experiment 1, 38 male goats ($27.4{\pm}5.7kg$ body weight) were randomly assigned to each of 5 treatments: i) BG alone and BG plus; ii) PEA; iii) LES; iv) MUC; and v) PAP. Goats were fed for ad libitum consumption and adapted to the diets for 14 d followed by 7 d of measurement. The PEA, LES, MUC (50%, 50%, and 10% of the diet dry matter [DM], respectively), and PAP (forced-fed at 10 g/d) were fed at rates that would elicit anthelmintic effects. In Experiment 2, goats remained in the same treatments but were allocated to 15 pens (3 pens per treatment) from d 22 to 63. All goats were infected with parasites by grazing an infected bahiagrass pasture from 0800 to 1500 h daily and then returned to the pens. Results: Dry matter intake tended to be greater in goats fed PEA and LES than those fed BG (757 and 745 vs 612 g/d, respectively). Digestibility of DM (59.5% vs 54.9%) and organic matter (60.8% vs 56.0%) were greater in goats fed MUC vs BG, respectively. In Experiment 2, feeding PAP, LES, and PEA to goats reduced nematode fecal egg counts by 72%, 52%, and 32%, reduced abomasal adult worm counts by 78%, 52%, and 42%, and decreased plasma haptoglobin concentrations by 42%, 40%, and 45% relative to feeding BG alone, respectively. Conclusion: Supplementation with PEA, LES, and PAP decreased the parasite burden of goats but did not increase their performance. PAP was the most effective anthelmintic supplement.

본 연구는 커피박 퇴비와 벨벳콩 식물체 분말 처리에 따른 고구마뿌리혹선충 살충효과를 평가하였다. 커피박 퇴비와 벨벳콩 식물체 분말 처리중, 1% 벨벳콩 식물체 분말 처리가 뿌리혹선충의 살충율이 83.2%로 가장 높게 나타났다. 또한 실내에서 호피무늬 벨벳콩 추출물 농도별로 처리한 시간의 경과에 따라 뿌리혹선충 유충의 치사율이 증가하였다. 호피무늬 벨벳콩 추출물 처리 24시간 후, 1.2%와 2.4% 농도에서 뿌리혹선충 유충의 치사율이 가장 높게 나타났다. 커피박 퇴비와 벨벳콩 식물체 분말 처리가 호박유묘의 생육에 미치는 영향을 조사하였더니 20% 커피박 퇴비 처리구는 호박 유묘의 생육을 억제하였으나 1% 호피무늬 벨벳콩 분말 처리구가 호박 유묘의 생육촉진효과가 가장 뛰어났다. 하지만 유기성 자원인 벨벳콩과 커피박 퇴비를 이용하여 유기농 호박 재배토양에서 발생하는 고구마뿌리혹선충을 효과적으로 방제하기 위한 재료로 사용하기 위해서는 처리농도와 방법에 대한 추가적인 연구가 필요할 것으로 생각한다.
