  • Pollen grains of 26 genera and 62 species of the Lythraceae were investigated by means of light microscopy. The result reveals that the family is divided into three pollen groups which are characterized by having a non-, 3- and 6-pseudocolpate aperture. The palynological study suggests a revision of the subfamilial division. Some taxonomic problems between the genera were discussed on the pollen morphology.

  • 여름철을 꽃으로 아름답게 장식하는 나무는 그리 많지 않은데, 그 중에서도 꽃, 잎, 수피, 수형 등 어느 한군데 나무랄 데 없는 나무가 있으니 바로 배롱나무속 식물들이다. 배롱나무속(Lagerstroemia)은 부처꽃과(Lythraceae)의 작거나 큰 나무로서 동남 아시아와 호주에 걸쳐 약 50여종이 분포하고 있다. 속명인 Lagerstroemia는 Linne의 친구인 스웨덴의 Magnus von Lagestrom(1696$\sim$1759)에서 유래되었다.

  • Hot water extracts of 141 indigenous plants were screened for antibacterial activity against 7 Gram (+) and 12 Gram (-) bacteria by agar diffusion method. Of the 141 plants tested, 55 showed antibacterial activity against one or more species of Gram (+) bacteria and especially extracts of Oenothera stricta Ledebour (Onagraceae), Quercus variabilis Blume (Fagaceae), Alnus firma (Betulaceae), Geranium thunbergii (Geraniaceae), Lagerstroemia indica (Lythraceae) showed broad spectrum antibacterial activity on over 6 strains. Of the 141 plants tested, 45 showed antibacterial activity against one or more species of Gram (-) bacteria and especially extracts of Oenothera stricta Ledebour (Onagraceae), Punica granatum (Lythraceae), Quercus variabilis Blume (Fagaceae), Schizandra chinensis Baillon (Magnoliaceae), Alnus firma (Betulaceae), Alnus hirsuta (Betulaceae), Magnolia kobus (Magnoliaceae) showed broad spectrum antibacterial activity on over 8 strains. The most active antibacterial plants were Oenothera stricta Ledebour (Onagraceae), Punica granatum (Lythraceae), Quercus variabilis Blume (Fagaceae), Schizandra chinensis Baillon (Magnoliaceae) which are edible as permitted by Korea Food & Drug Adminstration. With in-depth research, the hot water extracts of these plants can be applied as food preservatives and alternatives of antimicrobials for livestock feeds.

  • The genus Tinocallis Matsumura, 1919 is one of the large genera of the subfamily Calaphidinae with 19 species worldwide. From recent expeditions in Laos, we recognized the heavy infestation of Tinocallis himalayensis Ghosh, Ghosh & Raychaudhuri, 1971, which is new record in Laos, on Queen's crape-myrtle, Lagerstroemia speciosa (Lythraceae). In this paper, the diagnosis and illustrations for the alate viviparous female are provided with the images of live aphids and damage on host plant.

  • Woodfordia fruticosa Kurz (Lythraceae) is used in the treatment of various ailments in traditional medicines. DPPH activity guided fractionation and purification process was used to identify the free radical-scavenging components from the flowers of this plant. The methanolic extract of the plant was first fractionated into four extracts; namely, n-hexane, chloroform, ethyl acetate and water fractions. Among them, the ethyl acetate fraction was found to be the most effective and was further subjected to activity guided-fractionation and isolation procedures. After successive column chromatography on silica gel and Sephadex LH-20, gallic acid, which is responsible for the radical scavenging activity, was isolated and its structure was elucidated by spectral methods ($^1H$ NMR, $^{13}C$ NMR) and by comparison with literature.

  • Woodfordia fruticosa Kurz. (Lythraceae), commonly known as Dhayero, is used in the treatment of various ailments in Nepal. In this study, the antioxidant capacity of crude extract and different polarity fractions of Woodfordia fruticosa flowers were assayed for their scavenging abilities against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and nitric oxide radicals, competitive ${\beta}$-carotene bleaching, reducing power, metal chelating ability and total phenolic content. Crude extract and polar fractions showed stronger antioxidant capacity and contained very high level of total phenolics. They exhibited strong DPPH radical scavenging, nitric oxide scavenging and reducing power, medium ${\beta}$-carotene bleaching and poor metal chelating capacity. Positive correlation obtained between total phenolic content and antioxidant capacity assays, indicated the contribution of phenolics toards antioxidant capacity.

  • We examined methanol extracts prepared from the Korean plants for their inhibitory effects on rat lens aldose reductase (RLAR) activity in vitro. Among 41 plant extracts, the extracts of Lagerstroemia indica, Punica granatum, Eurya japonica, Liquidambar styraciflua, and Vitis coignetiae exhibited highest inhibitory potency, even more potent than tetramethylene glutaric acid (TMG), known as one of typical aldose reductase inhibitors $(IC_{50}\;value,\;0.51\;{\mu}g/ml)$. Especially, the extract of Lagerstroemia indica (Lythraceae), exhibited the most inhibitory potency $(IC_{50}\;value,\;0.069\;{\mu}/ml)$ on RLAR.

  • An experimental rearing of tropical tasar silkworm, Antheraea mylitta Drury was conducted to study silkworm-food plant-interaction and thereby to search for an alternate silkworm food plant. The silkworm-food-plant-interaction was studied with six different food plant species viz. Terminalia tomentosa, Terminalia arjuna, Terminalia belerica, Terminalia chebula of Combretaceae family and Lagerstroemia speciosa, Lagerstroemia parviflora of Lythraceae family. The rearing performance of silkworm on Lagerstroemia speciosa in terms of cocoons per DFL and silk ratio was found comparable with Terminalia tomentosa and Termonalia arjuna, the primary tasar silkworm food plant species. These three plant species also possessed better results in terms of physiological (leaf moisture content and net photosynthesis rate) and biochemical (Chlorophyll, protein, carbohydrate and crude fibre contents) characteristics to support silkworm rearing than Terminalia belerica, Terminalia chebula and Lagerstroemia parviflora. The correlation study between silkworm rearing performance and food plant's constituents indicates commercial perspective of Lagerstroemia speciosa as an alternate food plant for tasar silkworm rearing.

  • Banaba, Lagerstroemia speciosa (L.) Pers. (Lythraceae) is a tree that grows in the tropic islands of the Pacific. This plants are used for medical purposes in the world. The components of L. speciosa were analyzed for the contents according to growing stages at leaves. The distributions of the corosolic acid ($2{\alpha}$, $3{\beta}$-dihydroxyurs-12-en-28-oic acid), phytol, campestrol, and vitamin E were rich among samples in this study. These were contained much fatty acids. The mean content of palmitic acid was from 2.4% across all growing stages, varying from 2.15% for young leaves with the lowest content and 2.86% for fallen leaves with the highest content. Oleic acid, linoleic acid, and linolenic acid were contained nearly mean 2.0% in all leaves of banaba. Our results have shown that the phytochemical profile of young L. speciosa leaves differs quite radically from that of old L. speciosa leaves. In addition, these subdividing results according to plant growth should allow future researches to conduct targeted experimental studies and use of particular medical components of interest, examining chemical variation on the inter-developmental levels.
