Prunus speciosa (Koidz.) Nakai belonging to Prunoideae of Rosaceae, a species previously unrecorded in Korean flora, is described. Prunus speciosa (Koidz.) Nakai is similar to Prunus sargentii Rehder and Prunus jamasakura Siebold ex Koidz., but different because it has toothed lobes of calyx tubes with the apex of leaf serrations aristate. This species is naturalized widely in the eastern parts of Jeju Island but is endemic to Japan.

The distribution of Agrimonia gorovoii Rumjantsev in Korea is verified in this study. The species, described as from Primorsky Krai in Russia, was found in Chungcheongnam-do, Gangwon-do, Gyeonggi-do, and Jeollabuk-do provinces and in Incheon, South Korea. The species is characterized by ten stamens, deeply serrated leaflet margins, and long horizontal pilose stems. A Korean name, Gorovoi-jip-sin-na-mul, for the species is newly given, and a taxonomic description of the species and key to four Korea native Agrimonia taxa are presented.

From the roots of Rosa rugosa(Rosaceae), (+)-catechin, and a mixture of ${\beta}-sitosterol$ and campesterol glucosides were isolated and characterized by the physicochemical and spectral data.

Three compounds were isolated from the chloroform and n-butanol extracts of Filipendula glaberrima (Rosaceae). The structures of these isolates were elucidated as monotropitin, (+)-catechin, and ${\beta}-sitosteryl-3-O-{\beta}-D-glucopyranoside$ by spectroscopic analysis, and were identified by comparison of their spectra with those of reported ones.

Investigation of the fruits of Chaenomeles sinensis (Rosaceae) resulted in the isolation of a minor flavonoid. The structure of flavanone glycoside was determined to be as $2-hydroxynaringenin-7-O-{\beta}-glucoside$ on the basis of FAB-MS and spectral evidence, especially by 2D-NMR $(^1H-^1H\;COSY,\;HMQC,\;HMBC\;and\;NOESY)$.

안면도와 거제도에서 한반도 미기록식물인 장미과 산딸기속의 Rubus palmatus Thunb. var. palmatus을 발견하였고, 긴잎단풍딸기로 국명을 새롭게 부여하였다. 단풍딸기(R. palmatus var. coptophyllus (A. Gray) Kuntze)와는 잎이 3개로 갈라지거나 혹은 거의 갈라지지 않는 특징으로 구별된다. 또한 한반도 분포가 확인된 바 없는 단풍딸기의 거제도 분포를 처음으로 보고하였다. 마지막으로UPS에 소장된 Thunberg의 표본(UPS-THUNB. 12282)을 선정기준표본으로 지정하였다.

Prunus glandulosa Thunb. [=Cerasus glandulosa (Thunb.) Sokolov] (Rosaceae) is native to the warmtemperate region of China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hebei, Henan, Jiangsu, Shaanxi, Shandong, Sichuan, Yunnan, and Zhejiang Provinces). It is naturalized in the United States (i.e. Alabama, Michigan and North Carolina) and Canada (Ontario). This species, previously only recorded as introduced or cultivated plants on the Korean Peninsula, was confirmed to be naturally distributed in the southwestern coast islands(i.e. Geomun-do, Chuja-do and an uninhabited island in Shinan-gun of Jeollanam-do). Prunus glandulosa Thunb. is distinguished from a related taxon P. japonica var. nakaii (H. Lév.) Rehder by pedicel 8-12 (-16) mm long, linear stipules, glabrous style, and pink petals. The morphological characters and illustration of P. glandulosa Thunb. are provided with line drawings and photographs from the natural habitat. In addition, it is likely that a new habitat will be found by plant biodiversity investigations through the southwestern coast islands. Further research is needed to determine its population size, distribution, and threats, as well as identify appropriate locations for conservation collection of germplasm.

Very little utilization of the fruits of Malus baccata(Rosaceae) has been employed for food and medicinal plants except for preparing fruit beverages. But, it was estimated as valuable to investigate the chemical components for the botanical resource of this plant. In this study, it was found that the fruits of this plant contained primary long chain alcohol, ${\beta}-sitosterol$, campesterol, ursolic acid and ${\beta}-_D-glucosides$ of ${\beta}-sitosterol$ and campesterol. However, phloretin(dihydrochalcone) and its 5-O-glucoside(phloridzin) known as plant growth regulators in many Rosaceae plants were not found in this plant material by co-TLC analysis with authentic specimens. Although plant sex hormone, estrone, was often contained in relates of M. baccata, e.g., Prunus spp., Crataegus spp. and Malus spp., this compound was not detected in this fruit by comparison with an authentic material. By RIC chromatography, it was suggested that the Soxhlet extraction by the solvent of ether was excellently useful to extract ursolic acid efficiently.

Erwinia amylovora에 의해 발생하는 화상병은 2015년 국내에서 처음 보고된 이후 전국적으로 확산되고 있다. 화상병은 벌과 같은 화분매개충, 강한 바람을 동반한 강수와 이병주 전정 작업에 의한 전파 등 많은 경로를 통해 병원균 감염이 진행되어 발생한다. 이 외에도 자생하는 개야광나무속, 산사나무속, 피라칸다속, 벚나무속, 마가목속 등의 장미과 식물이 E. amylovora의 기주식물과 전파원이 될 수 있음이 보고되어 있다. 그러나, 국내에서는 아직까지 자생하고 있는 장미과 식물의 화상병 감수성에 관한 연구가 많이 다뤄지지 않은 상황이다. 본 연구에서는 2020년부터 2022년까지 3년간 국내에서 채집한 야생 장미과 식물 10속 25종을 대상으로 화상병 감수성 검정을 진행하였다. 10⁸ cfu/ml 농도의 E. amylovora 균액을 이용하여 채집한 식물의 꽃, 잎과 가지, 과실에 접종하고, 화상병 유사 병징 발현을 관찰하고 PCR을 통해 접종 조직 내의 E. amylovora 검출 여부를 분석하였다. 그 결과, 병징 발현과 병원균 검출 결과가 동일한 14종의 야생 장미과 식물을 확인하였다. 이러한 결과는 향후 적절한 화상병 방제 정책 수립에 기여할 수 있을 것으로 생각된다.
