Abstract

A study was conducted in determining the contents of alkaloid, tannin and nutritional Values from six browses fed to fattening cattle in Timor island. The samples Were gmelina (Gmelina arborea Roxb.),pates/lamtoro (Leucaena leucocephala [Lamk.J De Wit),daun kupu-kupu (Bauhinia malabarica Roxb.), gala-galaAuri (Sesbania grandiflora [Li Pers.l gamal (Gliriddia sep/um [lick] Steud.).and kabesak (Acacialeucoohloea Willd.).Samples were collected during wet and dry seasons.Results showed that total number of alkaloid compounds varied from 14 to 30.There was an increase in concentration for alkaloid and tannin from Wet to dry season, however the concentrations were low (< 1%).The increase in the concentrations between seasons Were ranged from 20% to 32096.Nutritional values of the browse during wet season were considered high, however there is a need in evaluating the nutritional values of the browses during dry season as well.

Abstract

YULIASRI JAMAL&G. PANGGABEAN. 1988 The effect of drying on the fat content of th chillies (Capsicum annuum L.). Berita Biologi 3(8) 374 - 376. The treating of chillies on various temperatures were studied in order to know their effect on the fat content.The chillies were dried in the refrigerator (12°C),in the room at ambient temperature (25°C ±2°C), in the sun shine (35°C ± 2°C) in the oven at various temperatures such as 40°C 50°C, 60°C, 70°C, 80°C, 90°C and 100°C.During the investigation were used cabe keriting and cabe besar biasa & it were obtained from the local market.The results of the observation that the highest fat content were found on the cabe keriting a 70 C drying as well as room temperature.The fat content of terated chillies, however, in the oven at 50°C, 60°C were similar 14%.Meanwhile,the dried chillies as the result on the sun shine was 3,5% fat content. The fat content of cabe besar biasa was significantly high at 70°C. The fat content of the chillies decreased rapidly on the treating in the sun shine.The chillies both cabe keriting and cabe besar biasa which were dried more than 60°C & in the sun shine, the pulp turned to brownish red, whereas the dried chillies in the refrigerator, at room temperature, 40°C, 50°C and 60°C the colour of the pulp were similar to the fresh fruits.

Abstract

Wati(Piper methysticum Forst.f.)leaves has been used as narcotic in some parts of Irian Jaya since longtime ago. The GCMS analysis of wati leaves organic extracts(hexane,chloroform, methanol)has detected 48 components consisted alkanes,oxygenated hydrocarbons, fatty acid, steroids and alkaloids,including 5 major components, i.e. dihydro kawain,anisol p-undecyl, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-on, levulinic acid and one of unknown component.Forty-three other minor components will be discussed.
