Samples of stems, leaves, shoots and fruit (N=36) from lowland, African rain forest are analyzed for nutrients, digestibility and digestion-inhibiting substances. Plants from which the samples are drawn are all important in the diet of western gorillas, large generalist herbivores in coastal Cameroon. Many of the plants are common in the early succession following disturbance to the forest. Analysis of food chemistry in relation to food preference indicates that lignin, digestibility and crude protein are the most significant factors in food selection for western gorillas at this site. Food chemistry of western gorillas is compared to food chemistry of mountain gorillas in the montane forest of East Africa. Foliage consumed by western gorillas contains more condensed tannin than does foliage consumed by mountain gorillas. The greater content of condensed tannin in the leaves consumed by western gorillas is related to the greater representation of woody plants in the western diet.
对来自非洲低地雨林的茎、叶、嫩枝和果实样本（N = 36）进行了营养成分、消化率和消化抑制物质的分析。采集样本的植物在喀麦隆沿海大型杂食性草食动物西部大猩猩的饮食中都很重要。许多植物在森林受到干扰后的早期演替中很常见。对与食物偏好相关的食物化学分析表明，木质素、消化率和粗蛋白是该地点西部大猩猩食物选择中最重要的因素。将西部大猩猩的食物化学与东非山地森林中山地大猩猩的食物化学进行了比较。西部大猩猩食用的树叶比山地大猩猩食用的树叶含有更多的缩合单宁。西部大猩猩食用的树叶中缩合单宁含量较高与西部饮食中木本植物的占比更大有关。
