| Summary: | Surveys on wild and semi-wild plants were conducted at four native markets
(Bintulu, Sibu, Sarikei and Selangau) in central Sarawak. This study was to
determine the availability, diversity, uses and the nutritional status of the
wild and semi-wild plants. Edible parts of the plants were brought back to
the laboratory and were subjected to proximate analyses, minerals and sugar
contents based on the standard methods. A total of 49 wild and semi-wild
plants were recorded with Sibu native markets have the highest number of
plants species (40 species and 25 families). The most abundant plant family
traded in the markets was Arecaceae (18.25 %) based on the trader involved.
Forty five species of wild and semi-wild plants recorded were consumed as
foods, two species (Helminthostachys zeylanica and Nephrolpeis biserrata) used
for both food and medicine, two species (Myrmecodia tuberosa and Lycopodiella
cernua) as medicine and two other species used as household items e.g., food
wrapper (Licuala spinosa) and mosquito repellent (Goniothalamus velutinus).
Based on the proximate analyses based on dry weight basis, the crude
protein for fruits (0.04-3.17%), vegetables (0.14-2.98%) and seeds (1.06-4.69%).
The crude fat content ranged from 0.04 to 18.06 % for fruits, 0.04 to 0.66% for
vegetables and 1.23 to 34.18% for seeds. Leafy vegetables such as Ficus
grossularioides provides good source of fiber (12.18%) while fruits provides
good source of carbohydrate ranged from 70.54 to 96.99%. The minerals
analyses indicated that ferns such Diplazium esculentum have high content of
P, Na, Mg and Ca which provides good source of minerals with affordable
price. The sugar contents (sucrose, fructose and glucose) of 11 fruits of wild
and semi-wild plants were analysed using HPLC. Results indicated that most
of the fruits analysed have high amount of glucose and fructose compared to
sucrose. Artocarpus odaratissimus recorded significantly high amount of
glucose (3.99 g per 100 g) and fructose (4.85 g per 100 g) compared to other
wild fruits. Information on the nutritional status of wild and semi-wild plants
also can help the agronomist in determining their potential as new crops and
increase their function in local diets. Documentation of traditional
knowledge on the uses of wild and semi-wild plants are important to provide
information on consumption, various uses, mode of preparation and
medicine for future utilization. |
