The n-hexane fraction from the stem bark of Lansium domesticum Corr. Cv. Kokosan afforded 3 sesquiterpenoids, namely eudesm-4(15),7-dien-1β-ol (1), eudesm-4(15)-ene-1β,6α-diol (2), and octahydro-4-hydroxy-3a-methyl-7-methylene-a-(1-methylethyl)-1H-indene-1-methanol (3). These three compounds were discovered in the Lansium genus for the first time. Their chemical structures were determined based on data generated from various spectroscopic methods, including one- and two-dimensional NMR, as well as mass spectroscopy. Sesquiterpenoid compounds (1-3) have also been evaluated on MCF-7 breast cancer cell lines and the compound 1 showed the strongest activity with an IC50 value of 17.97 µg/mL while compounds 2 and 3 showed moderate and weak activity with IC50 values of 121.65 and 201.57 µg/mL, respectively. The implication of the findings of these compounds is as an illustration that one of these sesquiterpenoids has potential as an anticancer with the presence of double bond which played important role in the cytotoxic activity that can be studied for new drug discovery.
Meliaceae plants are found worldwide in tropical or subtropical climates. They are important ethnobotanically as sources of traditional medicine, with 575 species and 51 genera. Previous research found that microorganisms are plant pioneers to produce secondary metabolites with diverse compound structures and bioactivities. Several plants of the Meliaceae family contain secondary metabolites isolated from endophytic fungi. Furthermore, related articles from 2002 to 2022 were collected from SciFinder, Google Scholar, and PubMed. About 276 compounds were isolated from endophytic fungi such as terpenoids, polyketides, lactones, pyrones, quinone, anthraquinones, xanthones, coumarines, isocoumarines, resorcylic acid lactones, cytochalasins, aromatics, ester, quinols, alkaloids, nitro compound, fatty acids, and sugars with bioactivities such as antioxidant, antibacterial, antifungal, anti-influenza, neuroprotective activities, anti-HIV, cytotoxic, allelopathic, anti-inflammatory, antifeedant effects, and BSLT toxicity. Meanwhile, secondary metabolites isolated from endophytic fungi were reported as one of the sources of active compounds for medicinal chemistry. This comprehensive review summarizes the ethnobotanical uses and secondary metabolites derived from Meliaceae endophytic fungi.
Objectives This study aims to review and describe the ethnobotanical, phytochemical and biological activity of various extracts and compounds isolated from Lansium domesticum Corr. from 1967 to 2022 and to study the opportunities that can be developed in the future in the pharmaceutical and pharmacology fields. The related articles, followed by the classification of L. domesticum Corr. according to ethnobotanical, biological and phytochemical properties, were collected from SciFinder, Google Scholar and PubMed. Key findings More than 80 compounds have been isolated and identified from L. domesticum Corr., including terpenoids and their glycosides. Furthermore, the pharmacological activity of the extracts and pure compounds of L. domesticum Corr. tested in vitro and in vivo were mainly confirmed to include antifeedant, antimalarial, antimicrobial, antibacterial, and radical scavenging activity, antimutagenic, and anticancer. Summary In conclusion, based on this review, all data on the phytochemical and biological activity of L. domesticum Corr. can be used to support scientists in further research aim to determine the reaction mechanism of the extracts or compounds and need to be further validated using in vivo models together with toxicological analysis to establish their maximum tolerated dose.
Lansium domesticum Corr. (L. domesticum), Meliaceae, has an economical fruit found throughout the southeast and has been reported to be used in traditional medicine. Therefore, this study aims to investigate the antimicrobial and cytotoxic potential of four extracts from the stembark of L. domesticum Corr. cv. Kokossan and isolated four terpenoid compounds. Antimicrobial testing was performed on two fungi, namely Malassezia furfur and Candida albicans, and two bacteria, Staphylococcus epidermidis and Klebsiella pneumoniae. Furthermore, antimicrobial activity was determined using the minimum inhibitory concentration (MIC). All isolated extracts were also tested on MCF-7 breast cancer cells. The results showed that butanol and n-hexane extracts have antimicrobial potential against K. pneumoniae bacteria with MIC values of 7.8125 mg/mL and 62.5 mg/mL, respectively, as well as against the dandruff fungus M. furfur. In addition to the antimicrobial results, the anticancer test results also showed that n-hexane has the most interesting cytotoxic value of all extracts, with an IC50 of 42.95 µg/mL than extracts of ethyl acetate, ethanol, and butanol with respective IC50 values of 72.84; 74.50, and 12088.33 µg/mL. The n-hexane and n-butanol extracts have anticancer and antimicrobial potential. These extracts can be studied further for other bioactivity.
Guarea is one of the largest genera of the American Meliaceae family, consisting of over 69 species which are widely distributed in Mexico, Argentina, and Africa and are used in traditional medicine for several diseases. Previous studies reported that the Guarea species produce secondary metabolites such as sesquiterpenoid, diterpenoid, triterpenoid, limonoid, steroid, and aromatic compounds. The preliminary chemical investigation commenced by isolating the limonoid compound, dihydrogedunin, in 1962; then, 240 compounds were obtained from the isolation and hydrodistillation process. Meanwhile, sesquiterpenoid is a significant compound with 52% of Guarea species. The extract and compounds were evaluated for their anti-inflammation, antimalarial, antiparasitic, antiprotozoal, antiviral, antimicrobial, insecticidal, antioxidant, phosphorylation inhibitor, and cytotoxic biological activities. The Guarea genus has also been reported as one of the sources of active compounds for medicinal chemistry. This review summarizes some descriptions regarding the types of Guarea species, especially ethnobotany and ethnopharmacology, such as the compounds isolated from the part of this genus, various isolation methods, and their bioactivities. The information can be used in further investigations to obtain more bioactive compounds and their reaction mechanisms.
