  • This research was performed to identify the anti-inflammatory constituent from the herb of Lycorus lucidus (Lamiaceae). The MeOH extract of this plant material and its two fractions, the lipophilic- ($CHCl_3$ fraction) and the hydrophilic fraction (BuOH fraction), were prepared to test anti-inflammatory activity. For this purpose, the inhibition rate on inducible nitric oxide synthase (iNOS) activity was assessed by determining nitric oxide (NO) formation in lipopolysaccharide (LPS)-induced macrophage 264.7 cells. The $CHCl_3$ fraction that greatly inhibited nitric NO formation was chromatographed to lead the isolation of ursolic acid. Since ursolic acid inhibited NO formation dose dependently in this study, this compound was considered as one of the active constituent responsible for anti-inflammation. However, the activity of rosmarinic acid isolated from the BuOH fraction was weak.

  • A comparative micromorphology of petal and sepal of 15 species of Lycopus was undertaken to assess their usefulness in species identification and to evaluate their significance in the taxonomy using scanning electron microscope and stereo microscope. Five types of trichome are found within the genus: unicellular cylindrical trichome, unicellular trichome with papillae, simple multicellular trichome, capitate glandular trichome, and peltate glandular trichome. The types, distribution, and density of the trichomes show considerable variation among the taxa. The distributional pattern of the unicellular cylindrical trichomes on inner side of corolla is differed among the investigated taxa, and can be classified into four patterns. The apex shape of sepal and the incised position of calyx are also various and be recognizedas four patterns. The shape of cell composing in both outer and inner sides of petal and sepal are shown variously. Finally, the taxonomic significance of micromorphology of the petal and sepal in identification and elucidation of the genus Lycopus, especially among the species is also briefly discussed.

  • 단삼(丹蔘) (Salvia miltiorrhiza)은 꿀풀과(일과(―科) Lamiaceae)에 속하는 다년생 초본으로, 중국이 원산지이며 약용하기 위해 우리나라에서도 널리 재배하고 있다. 신농본초경(神農本草經) 상품(上品)에 수재(收載)되어 있으며, 거어지통(祛瘀止痛), 양혈소종(凉血消腫), 청심제번(淸心除煩), 활혈조혈(活血調血) 등의 효능이 있어 부인과 질환에 많이 사용되고 있는 약재에 속한다. 본 연구에서는 단삼(丹蔘) 추출물이 흰쥐의 흉부 대동맥 절편에 어떠한 양상으로 작용하는지 확인하고자 하였으며, 그 결과 단삼 추출물 특히 헥산 분획에서 강력한 혈관 이완 작용이 나타났으며, 혈관 내피 세포의 존재 유무에 상관없이 농도 의존적으로 혈관을 이완시켰으나 혈관 내피 세포가 존재하는 상황에서 더욱 강력한 혈관 이완 작용을 보였다. 이러한 과정에 NO에 의한 cGMP 증가가 주요하게 작용하는 것으로 추정되었으며, 칼슘 통로 차단 효과에 의한 세포 내 $Ca^{2+}$의 감소도 관여하는 것으로 생각된다.

  • Nodal explants of Ocimum basilicum L. (Sweet basil, Lamiaceae), showed shoot proliferation after 7-10 days on MS media containing 1.5 mg/L kinetin. In vitro flowering was achieved from 90% of the shootlets which were sub cultured on a half strength MS media fortified with 5 mg/L BAP and 1 mg/L IAA. Cytokinin alone or in combination with $CA_3$and NAA resulted in shoot proliferation only. For rooting the plantlets were subcultured on MS basal medium supplemented with 3 mg/L NAA and rootlets emerged after 10 days of incubation. The survival percentage of transplanted plantlets was 70%.

  • Melissa parviflora Benth. is an aromatic perennial herb of Lamiaceae family. It is one of the most influencial plant and used from centuries in Unani system of medicine for the treatment of various malady such as Epilepsy (mirgi), hemiplegia (falij), migraine (shaqeeqa), insomnia (sehar), indigestion (sue hazm) and palpitation (khafqaan) etc. The Persian physician Avicenna endorsed it for heart problems. It has antitubercular, antipyretic, analgesic and stomachic properties, also used to remove bad breath from mouth, strengthen the gums but its main action is as a tranquillizer and nervine relaxant, it is greatly esteemed for its calming properties. Preliminary performed phytochemical analysis revealed that tannin, flavonoid and saponins are the major components of the plant extract. The plants containing saponins or flavonoids exhibit anticonvulsant activity whereas the flavonoids show various biological activities including antioxidant, anti-inflammatory and cytotoxic-antitumor etc. Keeping in view the tremendous medicinal importance of the plant Badranjboya in Unani Medicine, this review provides updated information on its phytochemistry, therapeutic uses and pharmacological properties.

  • The last four years of joint botanical collections by the governments of Myanmar and South Korea in Natma Taung National Park and adjacent areas in the Chin State of Myanmar have revealed the presence of 20 naturally occurring species of angiosperms new to the flora of Myanmar. Plants not previously recorded include species originally considered to be only found in neighboring mega-diverse countries. Examples (e.g., for India) include Boehmeria manipurensis Friis & Wilmot-Dear (Urticaceae), Trigonotis hookeri Benth. ex C. B. Clarke (Boraginaceae) and Mycetia radiciflora (C. B. Clarke) Airy Shaw (Rubiaceae); those for China include Microtoena delavayi Prain (Lamiaceae), Pimpinella kingdon-wardii H. Wolff (Apiaceae) and Senecio diversipinnus Y. Ling (Asteraceae). The data presented in this report are expected to be useful sources for phytogeographical studies of these species.

  • Since the first record of an anamorph of Neoerysiphe galeopsidis (syn. Erysiphe galeopsidis) on Lamium album subsp. barbatum in Korea in 1992, no scientific information has been added. Seven additional anamorphic samples (2003-2022) and one teleomorphic collection (November 2022) of N. galeopsidis on L. album subsp. barbatum in Korea enabled us to provide holomorph morphology and phylogeny of this powdery mildew for the first time. The presence of aerial hyphae around the chasmothecia was proposed and documented for the first time.

  • The distribution of orbicules was investigated for eleven taxa of six genera in Lamiaceae and four taxa of three genera in Verbenaceae using scanning electron microscopy. A literature survey to evaluate the phylogenetic potential of the orbicules and their possible correlations with tapetum types was also conducted. The orbicules are consistently absent in all investigated taxa of Lamiaceae, while small orbicules of an average size of less than $1{\mu}m$ are densely distributed in Verbenaceae. In fact, orbicules appear consistently in 123 of 150 angiosperm families when investigated in at least one species. Thus, the distribution patterns of orbicules could be a useful diagnostic character in angiosperms. In addition, orbicules occur in 84% taxa of the secretory tapetum type, while they are commonly absent in the amoeboid tapetum type (ca. 80%). The presence of orbicules may be correlated with the secretory tapetum type. However, the study of orbicules is restricted in 150 families and the tapetum type within these families can be applied for 92 families out of a total of 416 angiosperm families. Thus, further investigation of orbicules is necessary in extended taxa to address the questions pertaining to orbicules.

  • The nutlet morphology and pericarp structure of 14 taxa (4 taxa of the genus Glechoma and related taxa) were studied by light and scanning electron microscopy, and a detailed description of nutlet morphological features for all examined taxa is provided. The shape of the nutlet is ovate to elliptic. Its size is 1.36-3.83 mm in length and 0.80-2.65 mm in width. The largest one was found in Marmoritis rotundifolia, while the smallest one was in Agastache nepetoides. Three different surface types were recognized in the studied taxa based on differences in cell outline and cell boundary relief (rectangular, pitted, and ridged negative reticulate-cell). Three types of trichome (uni-cellular non-glandular trichome, multi-cellular non-glandular trichome, and peltate glandular trichome) were distributed in the nutlets. The pericarp is formed in three layers (i.e., exocarp, mesocarp, and endocarp including sclenchyma tissue), and the pericarp in the studied species is $39.0-237.5{\mu}m$ thick. The morphological and anatomical features (the nutlet shape, surface type, and trichome distribution) in the genus Glechoma and related taxa are described and discussed.
