Abstract

In this investigation, crude fat contents and fatty acid compositions of lipids present in the basidiocarps of widely distributed, medicinally important, wild mushrooms (Fuscoporia torulosa, Inonotus pachyphloeus, Phellinus allardii, Ph. fastuosus, Ph. gilvus and Ph. sanfordii) collected from different localities of Dehradun, Uttarakhand, India were analyzed. Gas chromatography with flame ionization detector was performed to identify and quantify the individual fatty acids present in the lipids of each mushroom. Mushrooms exhibited comparable amounts of crude fats with maximum content (0.35%) in Ph. sanfordii. The dominant fatty acid in the examined mushrooms was palmitic acid (C16:0). Oleic acid (C18:1n9c) and linoleic acid (C18:2n6c) exhibited maximum contents among the monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs), respectively. Saturated fatty acids (SFAs) in F. torulosa, I. pachyphloeus and Ph. fastuosus were at higher concentrations than unsaturated fatty acids (UFAs). Ph. allardii, Ph. gilvus and Ph. sanfordii exhibited greater amounts of UFAs compared with SFAs. Among UFAs, MUFAs dominated the polyunsaturated ones except for I. pachyphloeus and Ph. sanfordii. Of the polyunsaturated fatty acids (PUFAs), the contents of ω6 PUFAs were higher than ω3 PUFAs except for Ph. gilvus. Interestingly, a single trans fatty acid, elaidic acid (C18:1n-9t) (0.54-2.34%) was noticed in F. torulosa, Ph. fastuosus and Ph. sanfordii only. The examined mushrooms also differed in UFAs/SFAs, MUFAs/SFAs, PUFAs/SFAs, ∑ω6/∑ω3 and (linoleic acid) C18:2n6c/(oleic acid) C18:1n9c ratios. The presence of essential and non-essential fatty acids may make the examined mushrooms befitting candidates for use in nutraceuticals and pharmaceuticals.

印度几种木生药用蘑菇(木生菌)担子果皮的脂肪酸组成。
本研究对广泛分布于印度北阿坎德邦德拉顿不同地区的具有重要药用价值的野生蘑菇(Fuscoporia torulosa, Inonotus pachyphloeus, Phellinus allardii, Ph. fastuosus, Ph. gilvus和Ph. sanfordii)的子果皮中的粗脂肪含量和脂质脂肪酸组成进行了分析。气相色谱与火焰电离检测器进行鉴定和定量单个脂肪酸存在于每个蘑菇的脂质。香菇中粗脂肪含量相当,最高含量为0.35%。所检测的蘑菇中的优势脂肪酸是棕榈酸(C16:0)。油酸(C18:1n9c)和亚油酸(C18:2n6c)在单不饱和脂肪酸(mufa)和多不饱和脂肪酸(pufa)中含量最高。牛肉芽孢杆菌、厚叶芽孢杆菌和fastusus的饱和脂肪酸含量高于不饱和脂肪酸含量。与sfa相比,allardii, gilvus和sanfordii博士表现出更多的ufa。在UFAs中,多不饱和脂肪酸以mufa为主,但肿鼻假蝇和桑福特假蝇除外。多不饱和脂肪酸(PUFAs)中,除Ph. gilvus外,ω6 PUFAs含量均高于ω3 PUFAs。有趣的是,仅在F. torulosa, Ph. fastuosus和Ph. sanfordii中发现了一种单一的反式脂肪酸,elaidic酸(C18:1n-9t)(0.54-2.34%)。所测蘑菇的UFAs/ sfa、MUFAs/ sfa、PUFAs/ sfa、∑ω6/∑ω3和(亚油酸)C18:2n6c/(油酸)C18:1n9c比率也存在差异。必需脂肪酸和非必需脂肪酸的存在可能使所检测的蘑菇适合用于营养品和药品。

期刊介绍: The rapid growth of interest in medicinal mushrooms research is matched by the large number of disparate groups that currently publish in a wide range of publications. The International Journal of Medicinal Mushrooms is the one source of information that will draw together all aspects of this exciting and expanding field - a source that will keep you up to date with the latest issues and practice. The International Journal of Medicinal Mushrooms published original research articles and critical reviews on a broad range of subjects pertaining to medicinal mushrooms, including systematics, nomenclature, taxonomy, morphology, medicinal value, biotechnology, and much more.
