“…Several previous studies showed that S. zeylanicum was to have antimicrobial activity against P. aeruginosa, E. coli, P. vulgaris, S. aureus, K. pneumoniae, and Bacillus subtilis (Deepika et al 2014). The abundance of phenolic and flavonoid compounds in the S. zeylanicum contributes to its strong antimicrobial activity (Deepika et al 2014;Microbiol et al 2016;Palanisamy et al 2011;Shilpa and Krishnakumar 2015).…”

Abstract. Syarifah, Elfita, Widjajanti H, Setiawan A, Kurniawati AR. 2021. Diversity of endophytic fungi from the root bark of Syzygium zeylanicum, and the antibacterial activity of fungal extracts, and secondary metabolite. Biodiversitas 22: 4572-4582. The decoction of the root bark of Syzygium zeylanicum has been used as traditional medicine, such as for treating pathogenic bacterial infections. Endophytic fungi that live in medicinal plant tissues have a high species diversity and biological activities correlate with their host. Therefore, this study aimed to explore the diversity of endophytic fungi from the root bark of S. zeylanicum and to determine the antibacterial activity of endophytic fungi and their secondary metabolites. In this study, we isolate and identify the endophytic fungi from the root bark of S. zeylanicum, continued by screening their antibacterial activity against two Gram-negative bacteria (Escherichia coli InaCCB5 and Salmonella thypi ATCC1048 and two Gram-positive bacteria (Staphylococcus aureus InaCCB4 and Bacillus subtilis InaCCB1204) by the Kirby-Bauer method. The fungal extract with the highest antibacterial activity proceeded with the isolation and determination of the structure of their bioactive compounds. The isolates were morphologically identified. Isolates that showed strong antibacterial activity were identified by molecular identification. Isolation of bioactive compounds was carried out by chromatographic techniques and the determination of the structure of pure chemical compounds was performed by the spectroscopic analysis. In total, there were 8 isolates of endophytic fungi were obtained from the root bark of S. zeylanicum, namely SZR1 – SZR8. SZR2 isolate has the highest antibacterial activity. Molecular identification through phylogenetic analysis showed that SZR2 isolate had high similarity with Penicillium brefeldianum. Isolation of bioactive compounds from SZR2 produced compound 1 in the form of light yellow crystals which showed strong antibacterial activity against S. typhi, E. coli, and B. subtilis with MIC values of 64 g/mL. Compound 1 was identified as p-hydroxybenzaldehyde, which was also obtained in its host. In conclusion, the endophytic fungus Penicillium brefeldianum produces similar secondary metabolites and antibacterial activity as its host plant.

“…Syzygium caryophyllatum (L.) is an endemic tropical tree in Sri Lanka that belongs to the family Myrtaceae, bearing fruits during April -June, and they are blackish-purple color, which has a delicate but characteristic flavor combination of mildly sweet, sour, and astringent taste (Shilpa et al, 2015). These fruits can impart unique sensory characteristics into processed foods along with functional properties which can be used to upgrade human health as well (Shilpa et al, 2015). However, this fruit has been barely analyzed for its functional properties.…”

“…However, this fruit has been barely analyzed for its functional properties. Shilpa et al (2015) have reported that S. caryophyllatum fruits contain higher antioxidant activity compared to other commonly consumed fruits such as mango, papaya, apple, orange, and pomegranate. Although S. caryophyllatum fruit pulp possesses several beneficial characteristics relevant to sensorial and functional properties, this fruit is not utilized in the food industry up to now.…”

The perishable nature and seasonality of fruits make them harder to use in the food industry. Hence, the aim of this study is to preserve antioxidant-rich Syzygium caryophyllatum (L.) fruit using different drying techniques and evaluate the efficiency of drying methods in terms of antioxidant capacity. Fruits were dried using five different drying methods, namely, sun drying, dehumidified air drying, oven drying, vacuum drying, and freeze-drying. Highest 2,2-diphenyl-2-picryl-hydrazyl free radical scavenging activity (DPPH%) and Ferric reducing antioxidant power (FRAP) value retention were observed in vacuum drying and lowest in sun drying. Furthermore, during fruit drying, it is important to maintain the drying time as minimum as possible to minimize the loss of antioxidant activity. Therefore, vacuum drying was selected as the best drying method in preserving antioxidantrich Syzygium caryophyllatum (L.) fruit pulp.

“…S . caryophyllatum (Myrtaceae) is a large, evergreen tree and grows up to 15 m tall in high elevation (Shilpa & Krishnakumar, 2015; Subramanian, Subbramaniyan, & Raj, 2012) in tropical Africa, subtropical and tropical Asia (Nadarajan & Pujari, 2014), bears a dark purple color minor fruit that fruiting occurs in two seasons in April to July and November to January. Fruits are formed in clusters of 5–15, globose in shape.…”

“…Fruits are formed in clusters of 5–15, globose in shape. However, these fruits contain abundant phenolic compounds and anthocyanins which may possess a higher antioxidant capacity that has a major influence on sensory quality of the fruits, such as color, flavor, taste, and so forth along with health benefits (Shilpa & Krishnakumar, 2015).…”

Reverse spherification is a common technique used in molecular gastronomy to produce innovative products with an improved texture by shaping a liquid into an edible semisolid sphere that gives a burst in the mouth sensation. In this study, liquid-core hydrogel beads (LHBs) were prepared using Syzygium caryophyllatum fruit pulp adapting reverse-phase molecular gastronomy as a minimal processing technique to promote it as a healthy snack. Three types of hydrogel beads were formulated while considering the stability of LHBs. Long-term hardening of fruit juice in sodium alginate solution and the addition of plasticizer was used as two methods to increase the textural stability of LHBs. Results revealed that the addition of the plasticizer imparted to improve all the physical and textural properties of beads; however, it affects the transparency of the hydrogel membrane as well. Although the plasticizer increased the textural stability of LHBs, prolong inlaying them in it (the plasticizer) contribute to occur adverse consequences on the quality. Hence, the inlaying of LHBs in glycerol for 2 min was selected as the best treatment (HBP1). Since HBP1 had a low hardness (125.00 g) and high resilience (0.21), it imparted a chewing gumlike texture to LHBs. Hence, it (HBP1) can be used as a healthy snack. While HBP1 was capable of retained 90% antioxidant activity of fresh fruit of S. caryophyllatum, total polyphenolic content, 2,2-diphenyl-2-picryl-hydrazyl scavenging activity %, and ferric reducing antioxidant power value of this formulation were 59.50 GAE/g of dried LHBs, 68.96% and 139.69 TE/g of dried LHBs, respectively.
