芒果皮萃取物之抑菌及抗氧化活性分析

為了解決botany書的問題，作者張菀茜 這樣論述：

防腐劑在化妝保養品裡扮演重要角色，但有研究指出目前使用的化學防腐劑對人體有可能造成危害，因此開發天然的抗菌、抗氧化劑是當前的一個趨勢。芒果(Mangifera indica L.)是台灣重要的經濟作物，芒果皮是加工時主要的廢棄物，已被證實具有豐富的生物活性成分，因此本研究將評估芒果皮萃取物是否具有開發成天然防腐劑的潛力。研究利用芒果皮萃取物D50M和D100M評估其抗菌、抗氧化能力，以及測定萃取物的總酚、總類黃酮和總糖含量，最後依照《美國藥典》USP 51法規範所訂的五種菌株進行防腐效能試驗評估。抗菌活性先以紙錠擴散法分析，結果顯示萃取物對細菌皆有產生抑菌圈，真菌部分僅有D100M產生抑菌圈

。MIC和MBC的結果表明D50M具有抗菌和殺菌作用，但沒有抗真菌能力，D100M對所有檢測微生物均具有抑制能力，但不具殺死P. aeruginosa和真菌的能力。MIC結果中效果最好的是D50M對S. aureus以及D100M對S. aureus和B. subtilis，皆為0.25 mg/ml，MBC的最佳數值是D50M對S. aureus以及D100M對B. subtilis，為1 mg/ml。抗氧化實驗中，清除DPPH自由基和ABTS自由基的結果均顯示D100M相比D50M有較好的抗氧化能力。成分分析顯示D100M有較多的多酚(554.26 ± 16.15 mg GAE/g samp

le)和類黃酮(72.03 ± 1.23 mg QE/g sample)，而D50M較多的總糖含量(25.99 ± 2.73 %)。最後選用2 mg/ml D100M進行防腐效能試驗，結果顯示僅S. aureus和A. brasiliensis有達合格標準，因此未來若想應用於防腐劑可能需再進一步純化，找出更有效的成分。

Vegetal Sex: A Philosophy of Plants

為了解決botany書的問題，作者Sandford, Stella 這樣論述：

This book introduces the reader to the exciting new field of plant philosophy and takes it in a new direction to ask: what does it mean to say that plants are sexed? Do ’male’ and ’female’ really mean the same when applied to humans, trees, fungi and algae? Are the zoological categories of sex re

ally adequate for understanding the - uniquely ’dibiontic’ - life cycle of plants?Vegetal Sex addresses these questions through a detailed analysis of major moments in the history of plant sex, from Aristotle to the modern day. Tracing the transformations in the analogy between animals and plants th

at characterize this history, it shows how the analogy still functions in contemporary botany and asks: what would a non-zoocentric, plant-centred philosophy of vegetal sex be like? By showing how philosophy and botany have been and still are inextricably entwined, Vegetal Sex allows us to think veg

etal being and, perhaps, to recognize the vegetal in us all.

雪霸國家公園觀霧地區歸化植物之研究

為了解決botany書的問題，作者盧雅恩 這樣論述：

雪霸國家公園觀霧遊憩區自然景致十分豐富，而近年來因遊客量之增長，增加外來植物歸化及入侵之風險。本研究於2020年1月至2021年7月對遊憩區及相關林道、步道進行規劃植物調查研究，設置樣區以了解樣區兩年間之改變，最後以歸化植物侵略性評估表進行評估，並提出防治管理與建議。調查結果觀霧地區植物共記錄136科393屬760種，其中外來植物有27科70屬85種，占11.1 %，包含栽培植物記錄到20科31屬36種。歸化植物共記錄到13科40屬49種。以禾本科(Poaceae) 17種，種數最高，其次為菊科(Asteraceae) 13種。以原產溫帶地區者為優勢，占全部種數的58.8%。類地毯草(Axo

nopus affinis)覆蓋面積最高，達286.01 m2，其次為大扁雀麥(Bromus catharticus)，達160.95 m2。樣區調查結果顯示兩年間植群並無顯著差異，可能需長期之監測，本研究所設立之永久樣區可提供未來植物族群監測為所用。侵略性評估的部分，以大花咸豐草(Bidens pilosa var. radiata)、昭和草(Crassocephalum crepidioides)、大扁雀麥等物種現況總分最高，代表其潛在侵略性高。觀霧地區歸化植物所擴散之範圍僅限於人為活動頻繁的地區，為避免危害擴張，建議逐步移除入侵植物並建立原生植被替代被占據之棲地，並長期監測族群的擴散狀況

。又未來在進行中高海拔地區之歸化植物侵略性評估時可針對評估分數進行調整及加權，以建立出符合中高海拔之侵略性評估系統之參考依據。
