Sitophilus zeamais Motschulsky is the most important issue of rice storage as it decreases quality and quantity of the rice product. To replace dangerous chemical pesticides to resolve such problem, extracting natural substance to use as organic pesticide is thus explored and has gained momentum due to its safety and biodegradability. The natural substance could be derived from parts of plants such as seeds, fruits, shells, and rhizome.
Summary
Garcinia cowa is an edible plant commonly known in Thai as “Chamuang”. We have recently isolated a new polyprenylated benzophenone, namely “chamuangone” from G. cowa leaves. Chamuangone possessed a significant cytotoxic activity against lung adenocarcinoma (SBC3 and A549) and leukemia (K562, and K562/ADM) cells with IC50 values of 6.5, 7.5, 3.8, and 2.2 µM, respectively, as well as antibacterial activity against Streptococcus pyogenes (MIC 7.8 µg/mL), S. viridans and Helicobacter pylori (MICs 15.6 µg/mL), and Staphylococcus aureus, Bacillus subtilis and Enterococcus sp. (MICs 31.2 µg/mL) [1-2].
Ferns are ancient plants that have continuously evolved till today. A fern is a member of a group of approximately 250 genes, over 12,000 species, mostly grown in high-humidity tropical area but can also be found in subtropical and cold climate. Ferns are lower vascular plants that have neither seeds nor flowers, reproduce via spores and rely on water to sustain life cycle. Edible and herbal, ferns are also the queen of ornamental plants for their beautifully-shaped and colorful leaves lending to their popularity.
Rainbow trout (Oncorrhyncus mykiss) is in the family of salmon, live in cold water (less than 20C) and is also one of the economic fish in both tropical and cold countries like Europe, America, and Australia. Rainbow Trout was introduced to Thailand for the first time by The Royal Agricultural Station Inthanon in Chiangmai. Since then, rainbow trout farming has become one of the main economic activities among hill tribe families.
