Methanol extract of dried persimmon leaves was refractionated using hexane, chloroform, ethylacetate, n-butanol aqueous fractions. Among these chloroform fraction showed the highest inhibition rate on the mutagenicities of aflatoxin B₁(AFB₁) and 3,2' -dimethyl-4-amino-bipheny1(DMAB) in Salmonella typhimurium TA 100. Chloroform fraction was further fractionated into eight fractions by silica gel column chromatography and thin layer chromatography(TLC). The fraction 5 on TLC exhibited the highest antimutagenic activities in AFB₁and DMAB. 2,4-Decadienal, dihydro-4-methyl-2(3H)-furanone, hexanoic acid 1,4-bis(1-methy1 ethy1)benzene, heptanoic acid, phenol, octanoic acid, nonanoic acid and benzoic acid were tentatively identified from this antimutagenic fraction by GC-MS.

In other to investigate the hypolipidemic effect of dry edible leaves on serum lipids, four kinds of powdered leaves(persimmom, mulberry, perilla, and soy bean) were added to experimental diets at the levels of 5%(w/w). The diets were fed to 30 male Sprague-Dawley rats, aged 4 weeks and weighing 60$\pm$5g, for 3 weeks. Food intake was the largest in Group 1(control), with 5% of cellulose powder, while food efficiency was the highest in Group 2(persimmon). Total cholesterol level in serum was lower in Group 5(soybean) and Group 4(perilla) than the other groups. In comparison with Group 1, HDL-cholesterol level was very high in Group 4 and atherogenic index was low in Groups 4 and 5. Free cholesterol level was the highest in Group 2, and was the lowest in Group 1. Both LDL and LDL-cholesterol levels were the lowest in Group 1, while they were very high in Groups 2 and 3(mulberry). Triglyceride level was the lowest in Group 4, and the highest in Group 1. Except Group 3, all groups had lower phospholipid level than Group 1. Compared with Group 1, calcium level in serum was low in Groups 3, 4 and 5, magenesium level was low in Groups 2, 3 and 5, phosphate level was high in Group 4, and iron level was exceptionally low in Groups 4 and 5. In conclusion, Group 4(perilla) and Group 5 (soybean) showed a favorable effect in atherogenic index and serum levels of various lipids.

2010년부터 2011년까지 2년 동안 경상남도농업기술원 단감연구소 포장에서 단감 흰가루병(P. kakicola)을 방제하기 위하여 난황유를 3회 지상부에 살포한 다음 5일 후 병해 방제효과를 검정하였다. 난황유 처리구에서 병반 면적율을 조사한 결과 13.4%였으며, 단감 흰가루병에 대한 방제효율은 80.5%이었다. 무처리구에서 68.6% 발생하였다. 난황유를 처리한 후 주사전자현미경으로 관찰한 흰가루병의 균사는 형태적으로 세포가 원형질막이 파괴되어 세포내용물이 소실되어 쭈그러졌다. 이것은 난황유가 흰가루병의 세포벽이나 세포막을 파괴하여 생긴 것으로 사료된다.
