Twice field works to Wawonii Island was carried out in 2003 and 2004, in order to collect data on utilization of medicinal plants by local people. Two villages of Wawonii, which occupied by Wawonii tribe, were selected as study sites. Based on the study of 73 plants species, which uses by local people as traditional medicine and after having child were recorded. Similar to order inland areas of Indonesia, forest clearances and process of modernization was also occurred in this study area. Consequence the effect of those activities expected will beaffect in lost of local knowledge and destruction of natural resources. For that reason a study on utilizes of medicinal plant by local people is needed.© 2006 Jurusan Biologi FMIPA UNS SurakartaKeywords: traditional medicine; Wawonii tribe; Southeast Sulawesi.

An exploration and inventory of orchid plant was carried out in Wawonii Island, South-east Celebes. The aim of the study was to know about orchid diversity in the area, because no fi eld survey conducted since 1940. For that reason all orchid species fi nding were collected as life collection for planted in the Bogor Botanical Garden and dried collection for stored in the Herbarium Bogoriense. Ninety one orchid species were recorded and 36 species of them were new record of Celebes. Out of 1 species Trichoglottis javanica J. J. Sm. was recognized as endemic of Java. Five species orchid were endemic in Celebes, there are Bulbophyllum balapiuense J.J.Sm., Hyppeophyllum celebicum Schltr., Oberonia exaltata Schltr., Thrixspermum celebicum Schltr. and Malaxis lombasangensis (J.J.Sm.) S. Thomas Schut. and de Vogel.

During plant inventory work in the forested areas of Mt Mesehe and Mt Merbuk, Jembrana district, Bali, twenty orchid species were collected. Among the species collected, five were confirmed as new records for Bali. The five newly recorded species are Calanthe zollingeri Rchb.f., Plocoglottis plicata (Roxb.) Ormerod, Podochilus serpyllifolius (Blume) Lindl., Styloglossum speciosum (Blume) T.Yukawa & P.J.Cribb, and Vanilla albida Blume. Descriptions of taxa and images are provided.

Abstract. Praptiwi, Sulistiarini D, Qodrie ENP, Sahroni D. 2021. Antibacterial activity, antioxidant potential, total phenolic and flavonoids of three plant species of Rubiaceae from Banggai Island, Indonesia. Biodiversitas 22: 2773-2778. The present study was carried out to study the antioxidant and antibacterial potential of different plant parts (stems, leaves, and fruit) of the family Rubiaceae (Timonius celebicus, Psychotria celebica, Gardenia mutabilis) collected from the Banggai Islands. Screening of antibacterial activity against Staphylococcus aureus and Escherichia coli and antioxidant potential was carried out by Thin Layer Chromatography- Bioautography. Determination of IC50 and Minimum Inhibitory Concentration (MIC) was carried out by microdilution in a 96-well microplate. Total phenolic and total flavonoid content was determined by the colorimetric method. Total phenolic (TPC) and total flavonoid content (TFC) was varied from 29.78-380.99 mg GAE/g extract and 105.61-841.18 mg QE/g extract, respectively. The antioxidant capacity of three plant species was varied from moderate to very strong. Antioxidant Activity Index (AAI) was found more affected by TFC than TPC. The antibacterial activity of the extract against E. coli was weak, while some extracts have moderate antibacterial activity against S. aureus
