전남 가거도에서 양지꽃속의 신종인 가거양지꽃(Potentilla gageodoensis M. Kim)을 새로이 발견하여 기재하였다. 가거양지꽃은 잎은 우상복엽이며 엽신과 엽병에 털이 있고 3개의 정소엽이 측소엽보다 크며 포복경이 없어 양지꽃과 유사하다. 그러나 가거양지꽃은 잎은 두껍고 근생엽은 흔히 5장의 소엽으로 이루어졌으며 정소엽은 광난형이고 꽃잎이 크며 소엽 가장자리에 흰털이 밀생해서 흰색 테두리가 있는 것처럼 보인다. 반면에, 양지꽃은 잎은 얇고 근생엽은 흔히 7-13장의 소엽으로 이루어졌으며 정소엽은 타원형이고 꽃잎이 작으며 소엽 가장자리에 흰털이 적은 점에서 두 종이 뚜렷하게 차이가 난다.

Several $19{\alpha}$-hydroxyursane-type triterpenoids and hydrolysable tannins have beneficial effects on human health. Rubus crataegifolius (Rosaceae) has the cleft simple leaf whereas R. parvifolius has pinnate compound leaves. This research was aimed to find the variation in the contents of the triterpenoids and tannins between the infected versus uninfected leaves of R. coreanus and R. parvifolius and between young versus mature leaves. Triterpenoids and tannins were quantitatively analyzed by HPLC. Six triterpenoids including tormentic acid, euscaphic acid, 23-hydroxytormentic acid, coreanoside $F_1$, kaji-ichigoside $F_1$ and niga-ichigoside $F_1$ were used for standard compounds. Gallotannins and ellagitannins were quantitatively evaluated using the indicatives of methyl gallate and ellagic acid. The infected leaves of R. crataegifolius contained higher levels of triterpenoids and tannin than the uninfected leaves; however, lower quantity of total tannin was observed in the mature leaves than in the young leaves. Although the pinnate compound leaves of R. parvifolius exhibited similar tendency of those compositional variation with R. crataegifolius each other, its contents of triterpenoids do not considerably vary. Variation of the contents of triterpenoids and tannins were particularly distinct in R. crataegifolius by growth and infection.

항균 및 항산화활성이 우수한 산벚나무(Prunus Sargentii)심재 에탄올 추출물로부터 6개의 후라보노이드 화합물을 단리하였다. 이들을 기기분석한 결과, dihydroflavonol인 3,3',4',5,7-pentahydroxyflavanone(taxifolin)을 비롯하여flavanone인 5-hydroxy-7-methoxyflavanone(pinostrobin), 4',5,7-trihydroxyflavanone (naringenin), 3',4',5,7-tetrahydroxyflavanone(eriodictyol), 5,7-dihydroxyflavanone(pinocembrin), 그리고 flavanone의 배당체인 verecundin(7-hydroxyflavanone 5-O-${\beta}$-D-glucopyranoside)로 각각 동정되었다.
