Abstract
Mangosteen fruit (Garcinia mangostana L.) is consumed mainly for two purposes, i.e., its aril for fresh or minimally processed products and its rind for herb and other health-related products. In fact, due to the high portion of rind compared to its whole fruit, its rind has a more important economic value, especially for its α-mangostin content. This study reported the effects of flower baggings on the α-mangostin content during mangosteen fruit growth. This field research was conducted in a farmer’s field at Gisting village, Tanggamus District, Lampung Province, Indonesia. The study was arranged in a 2 × 3 factorial design. The first factor was bagging date [2 and 4 weeks after anthesis (WAA)], and the second one was bagging material (unbagged or control, banana ‘Cavendish’- paper bag, and balloon). Fruit samplings were conducted in every two weeks during the periods of 8-16 WAA. The α-mangostin content was analyzed with HPLC [DionexUltiMate® 3000, autosampler, column compartment, Ultimate 3000 pump, UV detector, column Enduro C-18 (250 mm × 4.6 mm, 5 µm) with C18 guard]. The results showed that the α-mangostin content increased in a sigmoid pattern during fruit growth, and the increase was mostly not affected by bagging, bagging materials, and application periods. The α-mangostin content increased tremendously during 10-14 WAA, regardless of bagging, bagging materials and application periods. Bagging had resulted in the decrease of α-mangostin content during the latest period of fruit growth, regardless of bagging materials and application periods
Highlights
Introduction innovationMangosteen (Garcinia mangostana L.) belongs to the family Clusiaceae or Guttiferae
To inhibit physiological causes and insect attack that led to yellow latex disorder, Widodo et al (2019) recommended that flower bagging should be applied, with the result was that paper bagging in 2 weeks after anthesis (WAA) resulted in the mangosteen fruit shelflife of 29 days compared to 4 WAA which resulted in 14 days shelf-life

The question is does flower bagging affect the α-mangostin content in its rind tissues?
