Objectives : The purpose of this study is to evaluate the quality of four different kinds of agarwood and analysis chemical constituents by GC-MS. Methods : Four source plants were two of Vietnamese agarwood, Indonesian agarwood and Myanmar agarwood. These plant materials were named sample No. 1-4. The chemical constituents of each agarwood were analysed by GC-MS. Results : GC-MS analysis showed that ${\beta}$-selinene was found in all the samples. The Vietnamese agarwood, Sample 1, and 4 has contained 6.861% and 7.497% of ${\beta}$-selinene and reached the highest level at the retention times 46.245 and 46.274 (min). Sample 2, the Myanmar agarwood has contained 1.608%, the lowest level of ${\beta}$-selinene, and it also has contained about 20% of ${\alpha}-,{\beta}-,{\gamma}$-eudesmol and 4.076% of valerianol. Sample 3, the Indonesian agarwood has contained 9.59% of ${\beta}$-selinene, 9.493% of ${\beta}$-selinene and shown its highest level (more than 19%) at the retention time 43.998 (min). Conclusion : It suggested that ${\beta}$-selinene could be a standard marker to evaluate agarwood by GC-MS analysis.

Gaining an understanding of bird communities in different habitat types is essential for the conservation of ecologically important habitats. Wetlands possess different types of habitats and provide an important environment for wintering waterbird communities. This study compares avian communities in five different habitat types in the Moeyungyi Wetland Wildlife Sanctuary (MWWS), Myanmar. From December 2014 to the first week of February in 2015, bird and habitat data were collected from representative areas of five habitat types (i.e., short grassland, tall grassland, lotus fields, open water areas, and rice fields) at MWWS. We established nine sampling plots in each habitat type, and used the point quadrat method to survey habitats and the point count method to survey birds in the habitats. Simple one-way analysis of variance (ANOVA) and post-hoc tests were used to determine differences between bird communities. We made 95 detections during 19 daily visits to each of the five habitat types. During the survey period, we recorded a total of 10,389 individuals belonging to 52 different bird species, based on 7-min observations at each of the 45 point count stations. Furthermore, we detected significant differences by habitat structure (i.e., vegetation coverage, height, and density; water depth; and plant species diversity) as well as bird communities (i.e., species richness, abundance, and diversity indices). In addition, the detailed analysis of 52 avian species revealed significant differences among 45 species with respect to the mean numbers of observed individuals in the survey habitats. The findings of this study revealed significant differences in the structure and composition of waterbird communities among the five assessed habitat types. Because natural marshes provide preferable habitats for a larger number and greater diversity of birds, relative to rice fields, natural marshes should be prioritized for conservation and restoration in Moeyungyi Wetland Wildlife Sanctuary.

Sparganium fallax Graebn. (Sparganiaceae), a species previously unrecorded for the Korean flora, was collected in a broad-leaved, evergreen swamp in the lowlands of eastern Jeju Island. This species was known to be distributed south of Jeju Island including Japan, South China, Taiwan, India, Indonesia (Sumatra), Myanmar, and New Guinea. S. fallax differ from others of Sparganiaceae in Korea by having keeled leaves, 4-7 staminate heads, relatively wide separation between each pistillate head and usually sessile or lowest pedunculated pistillate heads. The somatic chromosome number was 2n = 2x = 30 and the size of chromosomes was very small (0.69 to $2.19{\mu}m$).

Pteris griffithii Hook., one of the rarest fern species on the Indian subcontinent, is reported from Bhutan for the first time. The identity of this species was confirmed through morphological determination at the National Herbarium (THIM) of the National Biodiversity Centre (NBC) of Bhutan. It was found only in one location, in Gyelpozhing in eastern Bhutan, at an elevation of 521 m a.s.l. on 10 January 2016. Given that a very limited study of this species was conducted, the knowledge baseline with regard to its distribution is poor. It is also reported that this species has not been found for several years. The species is also considered to be very rare or critically endangered in some countries; however, there are no assessments on the International Union for Conservation of Nature (IUCN) Red List for this particular species. This paper attempts to provide baseline information considering its rarity and data deficiency. This species is also reported from the adjacent neighboring Indian state of Arunachal Pradesh as very rare, and also from Myanmar; however, confirmation of its presence in China is not clear at this time. Therefore, considering its data deficient status, we attempt to document it scientifically to create a knowledgebase pertaining to this particular species. Concurrently, this species merits further research to understand its distribution patterns in Bhutan and any related anthropogenic threats.

Bulbophyllum auricomum Lindl. is very popular among orchid growers due to the attractive fragrance of its flowers and has become an endangered orchid in Myanmar. In this study, we carried out an aseptic technique that can be used to conserve this endangered orchid species. The seeds of B. auricomum Lindl. were obtained from artificial pollination and cultured in MS basal medium for seed germination. The effect of coconut water and BAP in MS basal medium on callus induction was investigated. The highest callus induction was found at 2.0 mg/L BAP. The maximum growth of protocorm-like bodies (PLBs) was evaluated, and the best response was observed on MS medium supplemented with 150 mL/L coconut water at pH 5.6. MS basal medium supplemented with 150 mL/L coconut water along with 2.0 mg/L BAP and 1.0 mg/L NAA (MCBN) showed the highest number of plantlets at 15℃ at the second week of culture. At the second and third week of culture, MS medium supplemented with 2.0 mg/L BAP and 1.0 mg/L NAA (MBN) showed the best result in terms of the number of leaves and the longest leaves at 15℃ and 25℃, respectively. The present study showed evidence of successful in vitro propagation of B. auricomum Lindl.

Background: Safflower (Carthamus tinctorius L.) is a useful medicinal and oil crop in Korea. However, when safflower is cultivated, the flowering period overlaps with the rainy season, and seed maturation is poor. Therefore, this study aimed to use basic research data to develop superior varieties using agronomic characteristics and crossing method. Methods and Results: A total of 34 safflower germplasms were sown and their agronomic characteristics were investigated. Based on these investigations, the cultivar 'ui-san-hong-hwa' was selected as the mother plant, and 'Myanmar safflower' (Hsu Pan) was selected as the father plant. In addition, we developed a floret-protecting cap to cover florets after emasculation during the artificial crossing. When florets were protected by the cap, the seed setting rate increased in comparison to that in the non-covered florets. Conclusions: Agronomic characteristics can contribute to developing suitable varieties. The results suggest that the protection cap will be helpful in breeding without the floral organ drying. This study contributes an efficient breeding method to develop new safflower varieties.

Protaetia brevitarsis (PB) extracts has been traditionally used as medicinal stuff to treat blood stasis, occlusion of menstruation, tetanus and liver cancer in Asian countries (Korea, Japan, China, Taiwan, India and Myanmar). Especially, Donguibogam, which is traditional korean medicinal book, described the PB extracts as traditional medicine to treat hepatic diseases and vascular disorders. The PB extracts has been considered as highly nutritional food. The major constituents of PB extracts are rich in protein, healthy fats, iron, calcium. Recent studies announced that PB extracts has hepatoprotective effect and anti-microbacterial effect. However, the effect of PB on ulcerative colitis has not been uncovered yet. The aim of this study was to examine the anti-inflammatory effect of PB extracts in dextran sulfate sodium (DSS)-induced colitis mice model. Cytotoxicity of PB was determined by MTT assay and the antiinflammatory effect of PB extract was investigated by measuring nitric oxide (NO) production. PB extracts did not show any cytotoxicity. AIso, PB extracts supressed NO production in LPS-stimulated mice peritoneal macrophages. To determine whether PB could be an effective treatment on ulcerative colitis, DSS was administered in BALB/c mice for 10 days. PB extract significantly improved the clinical signs of DSS-induced UC, including body weight loss, colon length shortening, and disease activity index increase, with histological markers of colon injury. These findings indicated the possibility of PB as a therapeutic agent on ulcerative colitis.
