Abstract

Curcuma longa is a medicinal plant renowned for its therapeutic properties and potential treatment of cancer. This study focused on the biosynthesis of diterpenoids in the rhizome and leaves of C. longa. The genes responsible for producing these medicinal compounds were analyzed using BLASTx, Gene Ontology (GO) annotation, differential expression, and homology. The substantial dataset was obtained from the National Center for Biotechnology Information (NCBI), comprising 151,730,334 clean reads and 167,264 transcripts for the analysis. The results of the BLASTx analysis were as follows: NR yielded 65.93%, Swiss-Prot yielded 44.52%, and COG yielded 17.35%. Subsequently, GO annotation was performed using Blast2GO, resulting in an annotation rate of 56.79%. Differential expression analysis revealed a total of 636 genes that were significantly differentiated between the rhizome and leaves. The homology analysis resulted in 11 proteins associated with diterpenoid biosynthesis and nine proteins related to CYP450. Approximately three class I proteins were highly expressed in the rhizome. Additionally, seven CYP450 enzymes from the CYP71D and CYP726 subfamilies were identified; three were highly expressed in the rhizome. The expression patterns of these enzymes were similar to the aforementioned three class I diTPSs, indicating their potential involvement in macroditerpenoid biosynthesis in C. longa. These findings provide valuable genomic resources for future functional genomics research on C. longa, facilitating targeted efforts to enhance the production of bioactive compounds.

Abstract

Vincetoxicum villosum belongs to the Apocynaceae family. V. villosum is often used as a traditional medicine for treating jaundice, gallstones, kidney stones, hepatitis B, and liver diseases. This study aims to determine the metabolite profile and antioxidant activity of V. villosum to provide new information and serve as a reference for its safe use as a medicinal plant. The methods used to determine the metabolite profile involved GC-MS, and antioxidant activity was assessed using the DPPH method. GC-MS analysis showed that V. villosum leaf extract contains n-hexadecanoic acid, phytol, 9,12,15-octadecatrienoic acid (Z,Z,Z)-, and 2,4-di-tert-butylphenol which have potential antioxidant activity. The antioxidant activity in V. villosum leaves is classified as very weak, with  IC50 ranging 0.6 – 1.6 mg/mL, with the best antioxidant activity observed in polar solvents (ethanol extract) with a maceration time of 72 hours. The highest total phenol content was obtained using ethanol solvent with a maceration time of 72 hours, amounting to 416.17 mg GAE/g, and the highest total flavonoid content was obtained using ethyl acetate solvent with a maceration time of 24 hours, amounting to 168.78 mg QE/g
