In Vitro Anti Angiogenetic Activity of Traditional Plants Saraca asoca, Glycyrrhizia glabra and Curcuma longa Beneficial for Endometriosis Treatment

The development of angiogenesis plays an essential role in the growth and survival of endometriosis. The aim was to determine the in vitro anti-angiogenic effect of Saraca asoca, Glycyrrhiza glabra, and Curcuma longa ethanolic extract in chick embryos by emphasizing its total phenolic and flavonoid contents in the sample. It was determined by Folin-Ciocalteu and aluminum chloride methods respectively. Anti-angiogenesis assay was done in chorioallantoic membrane. The high amount of total phenol and flavonoid was obtained from all three plant extracts and may be responsible for the bioactivity of the crude extract. Saraca asoca exhibits high phenolic content and anti-angiogenic activity followed by Curcuma longa with rich flavonoid and Glycyrrhiza glabra showed moderate activity for all the assays. A significant anti-angiogenic effect was observed for Saraca asoca (73.65+0.021) % and Curcuma longa (67.65+0.024) % than reference drug dienogest (62.42+0.02) % in the study. Search for new therapeutic agents with anti-angiogenic potential rich in plant secondary metabolites like phenols and flavonoids are need of the hour. The results successfully reveal that the abovementioned plants used in traditional medicines could be used for treating angiogenesis-related diseases like endometriosis.

ABSTRACT
Curcuma longa L. commonly known as turmeric is used as a culinary spice in India and many Asian countries. Turmeric has anti-fungal, anti-bacterial, anti-malarial and anti-cancer properties to mention a few. We have analyzed the transcriptome of C. longa retrieved from NCBI SRA database (SRR495223) for the development and validation of EST-SSR markers and identification of EST-InDels to be used for C. longa and related genera. A total of 337 primers were developed and 20 primers having the rating of 100% with the help of NetPrimer were selected and used for PCR validation in C. longa, Amomum subulatum Roxb. (large cardamom) and Elettaria cardamomum (L.) Maton (small cardamom). It was found that around 50% primers generated PCR products in both types of cardamom and 85% in C. longa. The developed primers worked with curcuma, large cardamom and small cardamom plants at varying levels. Besides, the transcriptome analysis detected high amount of deletion and 18 addition of bases which could be screened through the development of CAPS markers using the tool SNP2CAPS and it was found that 93 restriction enzyme can be used for screening these InDels.

Highlights

• Transcriptome sequence of Curcuma longa was used for the development of EST-SSR markers.
• The EST-SSR primers were validated in Curcuma longa and its related taxa such as Amomum subulatum and Elettaria cardamomum
• EST-InDels were also successfully identified in the transcriptome sequences of Curcuma longa.
