Abstract

The presence of fungi in nature is very abundant, but at this time it is still necessary to know and explore the various types that are able to live in various places. Fungi can live in plant tissue, known as endophytic fungi, and can also live on the leaf surface of a plant. Avicennia marina lives on the coast and is used to reduce abrasion, besides being able to live in tidal habitats and high salinity levels. This is supported by the plant's physiology and the help of its microbial symbionts, therefore it is necessary to explore fungi, especially fungi that are able to symbionting with these plants because they are thought to be resistant to high levels of salinity. The purpose of this study was to determine the types of molds that have been isolated and are able to live in the tissue and leaf surface of A. marina. Characterization method was reviewed through macroscopic and microscopic morphology using a microscope and compared with literature from various sources. The characterization results of the 12 isolates obtained several genera, including Trichoderma, Aspergillus, Penicillium, Curvularia, Paecilomyces, Talaromyces, Syncephalastrum, and 1 unidentified isolate. These isolates need to be continued with further research to see their ability to produce metabolites and so on.

Abstract

Renggak (Amomum dealbatum Roxb.) is a species from the genus Amomum widely spread in Lombok. Traditionally, Amomum dealbatum Roxb. (renggak) is an antiseptic to treat rheumatism and arthritis. However, there was limited report of its phytochemical contents and biological activity of Amomum dealbatum Roxb. This study is preliminary research that aims to determine the phytochemical content of Amomum dealbatum Roxb. leaf decoction and its ethanolic extract. For this study, we used two different extraction methods. The fully powdered plant used for the successive extraction in the cold process for maceration methods was 800 g, and ethanols were used as solvents. We used a traditional receipt that utilized three fresh leaves in the decoction methods with 4,5 L of water as solvents. Phytochemical screening was carried out qualitatively by using the tube method with specific reagents for each compound. Important phytochemicals that were screened are flavonoids, alkaloids, tannins, saponins, steroids, and triterpenoids. Phytochemical screening from plant extract and decoction revealed the presence of flavonoids, alkaloids, and tannins. Triterpenoid was only detected on the extract, and none of the extract and decoction have saponins and steroids. Our finding provides information about secondary metabolites that present in Amomum dealbatum Roxb. These phytochemical findings are essential and might be useful as quality parameters and to predicts its biological activities.

Abstract

Gyrinops versteegii is an endemic plant in eastern Indonesia that produced agarwood with high quality and economic value. This plant has been threatened by overexploitation which leads on decreasing in the natural population. This research aimed to induce in vitro callus formation to support the sustainable utilization of G. versteegii, which in the end, may support plant productivity. Callus induction was investigated using cotyledon and cultured on MS medium supplemented with several combination of plant growth regulators. The observations were done for the number of explants turned into callus and the duration for the first callus formation. The results showed that combination of 3 mg/L NAA + 0.5 mg/L BAP was recorded as the best combination for callus induction (63.63%). Callus with friable structure and bright color are obtained within nine days of incubation and showed the characteristic of embryonic callus. This result is expected to give a significant opportunity to conserve the natural population of G. versteegii.

Abstract

One of the most unique plant groups in the world is carnivorous plants. Indonesia is home to many species of this plant group. Nepenthaceae, represented by single genus Nepenthes, is relatively well known, but the others are not. A literature study and several field trips were conducted to give a summary of the diversity and the potential uses of the non-Nepenthes carnivorous plants in Indonesia. Three families with a total number of 29 species have been reported for Indonesia, namely Lentibulariaceae (20 species), Droseraceae (8 species), and Byblidaceae (1 species). One species, Aldrovanda vesiculosa is listed as Endangered based on IUCN Red List. The results reveal that several species possess ethnobotanical and medicinal uses as well as other potential such as in phytoremediation and nanoparticle biosynthesis. Several bioactivities have been reported such as anticancer, antihypertensive, antitumor, antioxidant, antibacterial, or even hepatoprotective. Among the most important bioactivity is anticancer which is supported by the presence of secondary metabolites named plumbagin, which so far has been found in three species. Our result indicates that this plant group is highly potential and warrants further studies and or development.
