Introduction
Developed in Hex: EtOAc (3: 1)
Compound 1 against four strains of
human pathogenic bacteria
Documentation of traditional knowledge on medicinal plants was carried out all around the world. The endeavours is to continue the poor transmission of traditional knowledge to younger generations, this knowledge is important in the exploitation of plants pharmaceutical industries, and the need to conserve rare or highly demanded plant species in traditional medicine. Traditional medicinal plants documentations and research were started in early 1980s in Sabah. The medicinal herb, Lindera polyantha (Bl.) Boerl. is listed one of the 1,300 medicinal herbs by Kulip in However, there is no research for chemical analysis against Lindera polyantha (Bl.) Boerl. Hence, we report the phytochemical analysis as well as bioactivities of isolated pure compounds from this plant and create healthy drink using traditional knowledge in Sabah.

Antibacterial Bioassay
The ethanolic extract yielded three pure compounds by chromatographic techniques. These major secondary metabolites such as 5-hydroxy-2-(10-hydroxy-40-oxo-cyclohex-20-en-10-yl)-6,7-dimethoxy-2,3-dihydro-4H-chromen-4-one (1), linderone (2) and methyllinderone (3) were elucidated based on NMR spectroscopic analysis. Besides, these compounds reported various biological activities such as anti-inflammation, anti-fungal, anti-oxidant and anti-cancer which suggested that these compounds could be used as lead pharmaceutical agents.

Results and Discussion
Finally, our ongoing effort in collaboration with the company, Pemborong Mangkab Enterprise (PME) to create new traditional medicinal healthy drink has provided a new market for investors and researches to enjoy the fruitfulness of sustainable development.
1. Identification of the plant
Lindera polyantha (Bl.) Boerl. or local name as Roiros (Dusun Tuaran, Sabah) was an endemic evergreen tree grows in Borneo Island. It has fragrance and was a traditional local medicine used for treating several symptoms. According to the ethnobotanical studies by Kulip in 1996, it was used as anti itchy, blood cleansing and to get rid of gas in Dusun community since time immemorial.
Novelty and Inventiveness
1. Three bioactive secondary metabolites were isolated.
2. Published two international and one domestic journals.
2. Extraction, Isolation and Structure Elucidation
