“…The total carotenoids tended to decline at the end of the storage experiment (8 dap), although not reaching statistical significance (p < 0.05). The retinol activity equivalents (RAEs) amounted to 2.5-3.2 µg RAE/100 g of FW, thus being in the range of the 0.3 to 7.3 µg RAE/100 g of FW previously reported in the flesh of 'Sugar Loaf', 'Smooth Cayenne', 'MD2', and 'Queen Victoria' pineapples from Ghana [11]. In the present study, the impact of harvest maturity and post-processing storage on the (all-E)-β-carotene and total carotenoid levels of fresh-cut pineapples were found to be insignificant and thus, not further investigated.…”

“…TA expressed as g citric acid per 100 g of fresh weight (FW) was determined with a Titrino 702 SM (Metrohm, Herisau, Switzerland) titration system [4]. The concentrations of (all-E)-β-carotene and total carotenoids were determined by HPLC-DAD as detailed elsewhere [11]. Retinol activity equivalents (RAEs) were calculated by converting 12 µg dietary (all-E)-β-carotene to 1 µg RAE [12].…”

Green-ripe pineapples are shipped overseas by sea freight, while those picked at full maturity need to be transported by airfreight over the same large distance. In this study, fresh-cut pineapple cubes were assessed two, five, and eight days after processing from green-ripe pineapples after mimicked sea freigh (SF) and fully ripe air-freighted (AF) pineapples. The sea-freighted samples displayed elevated titratable acidity (TA), thus resulting in smaller ratios of total soluble solids and TA compared to the AF pineapples. Differences in the carotenoid levels of the two fresh-cut categories were found to be insignificant. By contrast, hierarchical cluster analysis (HCA) and principal component analysis (PCA) calculated on the basis of the volatiles analysed by headspace solid-phase microextraction–gas chromatography–mass spectrometry (HS-SPME–GC–MS) permitted to distinguish all six individual sample types and to segregate them into two major clusters (SF and AF). The effect of storage on the volatiles was further evaluated by partial least squares (PLS) regression. Substantial chemical markers to differentiate the individual samples and to describe the effect of storage were deduced from the PCA and PLS regression, respectively. In general, fresh-cut products obtained from fully ripe AF fruit displayed higher concentrations of volatiles, in particular, increased concentrations of diverse methyl esters. With progressing storage duration, the concentrations of ethanol and diverse ethyl esters increased. Moreover, products from AF pineapples displayed lower microbial counts compared to those from SF fruit.

“…Esto se asocia con las las propiedades fitoquímicas del arroz, el cual contiene flavonoides y en algunos tipos de antocianinas (Nayeem et al, 2021;Ratseewo et al, 2019). Además, en la cáscara de piña y en los pequeños tozos de pulpa se encuentran pigmentos como: clorofila (Feofitina), xantofilas (Violaxantina) y carotenos (Luteína) (Chutintrasri & Noomhorm, 2007;Steingass et al, 2020).…”

“…is the third most important tropical succulent fruit, after banana and citrus. It is seasonal and highly perishable [21,22] and majorly produced in Latin America and Southeast Asia. It has several health benefits due to the high contents of bioactive compounds including carbohydrates, glycosides, organic acids, proteins, polyphenols, vitamins, and other compounds [23][24][25].…”

“…It is an herbaceous perennial monocotyledonous plant belonging to the family Bromeliaceae (Annonaceae) and subfamily Bromelioideae with about 2000 species and an annual global production of over 14 million tons. The aroma, color, flavor, juiciness, texture, sweetness, and overall appearance of the pineapple flesh are among the most important contributing factors to its acceptance by consumers [22]. Pineapple is very rich in bioactive and volatile compounds, phenolic compounds, dietary fiber, minerals (such as calcium, potassium), nutrients, and vitamins (such as vitamin C, and vitamin A), thus, offering several health benefits such as antioxidant and anti-inflammatory activities, anti-obesity and dyslipidemia functions, monitoring of nervous system function as well as healing of bowel movement [26].…”

Ethnomedicinal Uses of Some Common Malaysian Medicinal Plants

Historically, natural products have always been a rich source of novel pharmacological leads, thus, making the ethnobotanical and ethnopharmacological knowledge an important and major asset of the medicinal plant-based drug discovery in providing hints for effective and safe chemotherapeutic compounds. Such knowledge, however, requires a thorough review and documentation of the ethnomedicinal and indigenous uses of local plants of every part of the world. Malaysia is a global hub for natural products which contributes to its GDP. Malaysia is also one of the 12 most diverse Megabiodiversity countries. Its rainforest is ranked 4th on the list of biodiversity hotspots in Asia after India, China, and Indonesia and is also acknowledged as the world’s oldest rainforest. Natural products are relevant to both Malaysian health care and agriculture which are parts of the national key economic areas (NKEA) under the Government’s Economic Transformation Plan as well as parts of the United Nations’ 17 Sustainable Development Goals (SDGs). Though the quality, efficacy, and safety of herbal products require global and international standardization, herbal products should be made accessible to low-income and rural communities across the globe. The proper documentation of the ethnopharmacological important plants in addition to their preservation and cultivation would enhance the sustainable use of the various indigenous plants. This work is unique in the sense that it is meant to review some of the most important high-value herbal products in Malaysia. Though it covers only a few representatives of Malaysian medicinal plants.
