A clerodane type diterpene, nasimalun A was isolated from a dichloromethane extract of the leaves of Croton oblongifolius Roxb. Nasimalun A showed moderate cytotoxicity toward MOLT- 3 cell line with IC50 value of 26.44 µg/mL. Furthermore, nasimalun A showed minimum inhibitory concentration (MIC) of 50, 12.5, and100 μg/mL for Bacillus cereus and both Staphylococcus aureus, and Staphylococcus epidermidis respectively.

This paper provides a synopsis of 104 genera of eriophyoid mites in Southeast Asia, with an identification key to families and genera, and a checklist of 325 species. A new species—Paniculatus curcasis sp. nov. on Jatropha curcas (Euphorbiaceae) from Java, Indonesia—was described. Four new combinations were proposed—Cosella crotoni (Boczek & Chandrapatya, 2000), comb. nov. on Croton oblongifolius (Euphorbiaceae) from Thailand; Paraphytoptus binarius (Keifer, 1977), comb. nov. on Peltophorum pterocarpum (Fabaceae) from Thailand; Leipothrix mangiferae (Chandrapatya, 1997), comb. nov. on Mangifera indica (Anacardiaceae) from Thailand; and Levonga caseariae (Chandrapatya, 1997) comb. nov. on Casearia grewiaefolia (Flacourtiaceae) from Thailand. Four new names were proposed for junior homonyms—Quadriporca samphran nom. nov. on Mangifera indica (Anacardiaceae) from Thailand; Knorella blumcanae nom. nov. on Bambusa blumcana (Poaceae) from Thailand; Rhombacus bangkoki nom. nov. on Eucalyptus sp. (Myrtaceae) from Thailand; and Tetra stipularisis nom. nov. on Bridelia stipularis (Euphorbiaceae) from Thailand.

The essential oil of C. oblongifolius Roxb. stem bark was obtained by hydrodistillation. Chemical analysis by GC-MS identified 29 compounds. Terpinen-4-ol (17.8%) was a major component, together with α-guaiene (7.9%), E-caryophyllene (7.0%), myrcene (6.7%), (+)-cyclosativene (5.1%), sabinene (4.8%), aciphyllene (4.7%), pogostol (4.6%), γ-terpinene (3.4%), α-muurolol (3.2%) and germecrene D (3.2%). The essential oil exhibited antibacterial activity against Propionibacterium acnes ATCC 6919 with an MIC of 0.125%, v/v.

Medicinal plants are a reservoir of biologically active compounds with therapeutic properties that over time have been reported and used by diverse groups of people for treatment of various diseases. This review covers 15 selected medicinal plants distributed in Myanmar, including Dalbergia cultrata, Eriosema chinense, Erythrina suberosa, Millettia pendula, Sesbania grandiflora, Tadehagi triquetrum, Andrographis echioides, Barleria cristata, Justicia gendarussa, Premna integrifolia, Vitex trifolia, Acacia pennata, Cassia auriculata, Croton oblongifolius and Glycomis pentaphylla. Investigation of the phytochemical constituents, biological and pharmacological activities of the selected medicinal plants is reported. This study aims at providing a collection of publications on the species of selected medicinal plants in Myanmar along with a critical review of the literature data. As a country, Myanmar appears to be a source of traditional drugs that have not yet been scientifically investigated. This review will be support for further investigations on the pharmacological activity of medicinal plant species in Myanmar.
