Abstract

The bark of  Albizia lebeckioides  and  Albizia falcataria  have been examined for their chemical constituents. A. lebeckioides has yielded the steroidal ketone, stigmasta-4,22-dien-3-one, and a triterpene alcohol as the major neutral components.  A. falcataria  has yielded a similar triterpene  and fatty ester as its major constituents. The toxicity of the compounds was evaluated in bioassay against termites. The results showed that lupenone and stigmastadienone were toxic  ioNeotermes dalbergiae  species. In contrast these compounds were less toxic to Cryptotermes cynocephalus species.

Abstract

Screening of 12 species of  Shorea  and 2 species of  Anisoptera  from the forest of Pasir Mayang, Jambi with brine shrimp (Anemia salina) lethality bioassay showed that Shorea gibosa and Anisoptera marginata  have sufficient activity for further investigation. Bioassay-guided fractionation of the active extract of  S. gibosa  led to the isolation of stigmasterol and the shoreaphenol. Bioassay-guided fractionation of the active extract of A. marginata resulted in the isolation of lupenone and 3-methoxy-4-hydroxybenzoic acid O-p-C glucopyranoside as the bioactive compound. Key words: Plant natural products/Sftorea gibosalAnisoptera marginatalActive extracts/Bioassay/Pasir Mayang.

Abstract

This article presents the results of an investigation concerning the use of herbal medicinal plants by the people of Pasir Mayang, sub-District (Municipality) of VII Koto, District of Tebo, Jambi Province, Sumatera. The data collection was based on interviews with the healers and other villagers of Pasir Mayang who possess knowledge of the different plants and their medicinal uses. The study recorded 57 species of medicinal plants used in Pasir Mayang. The detailed uses of the 57 medicinal plants are given. All plant species were subjected to phytochemical analysis and toxicity tests, and the outcome of the analysis on the presence of alkaloids, saponins, steroids/terpenoids, and the level of  toxicity against brine shrimp (Anemia salina) are presented. A comparison with other studies reported in the literature seems to indicate that a high frequency of the use of leaves in therapy may be a part of a larger cultural phenomenon among the tropical forest tribes of Southeast Asia.
