Does anyone know of a source of seeds or fresh plant material of Catharanthus pusillus?

Angiosperms are defined by double fertilization, one sperm cell from the pollen tube fertilizes the egg cell and the other one forms the endosperm. In orchids there is no endosperm. So is there double fertilization in orchids?

To me looks like member of fabaceae. Earlier I was thinking, it is some sp. of Polygala as the flowers are similar looking.

It is herb of about 30-40 cm height. Originally collected from meghalaya, north east India. It flowers in July-August

I'm doing some work with Rhamnus staddo but there seems to be scanty information on the plant, the genus Rhamnus and the family Rhamnacea

Apparently are similars

Very small leaves over creeping main branch. No adequate water supply required (mostly I observed this plant growing in soil deposits between the small cuts and grooves of a rock or stone). Upon cut of brownish stem a white latex like liquid oozes out. Leaves are not thick and stem has a little stretching capability not like rubber.  

Choongan Caralluma

Caralluma Tuberculata

Urdu: Chongan

English: Bitter Cress

Pushto: Pamankay

It is a wild plant used as a food. Its taste is bitter.

It is found in Africa, Saudi Arabia, India, Pakistan, Afghanistan and Southern Europe.

I have performed GC-MS analysis of Phytochemicals from a medicinal plants and also identified compound using NIST library. After NIST identification, I have a list of compounds. I am constructing a phytoconstituent table for manuscript which include compound name, retention time, area percentage, molecular formula and nature of compounds. I am trying to identify the class/nature of phytochemicals (like flavonoids, carotenoids, phenols or polyphenols, glycosides, tannins etc). For that, I am searching each compounds on databases like PlantaeDB, IMPPAT 2.0, website like MedChemExpress and also literature search. Some compounds can be find here but many of the are not to be found anywhere.

1. How to identify the class of phytochemicals or secondary metabolites after GC_MS and NIST identification?

2. Some compounds are repeated with different retention time and Similarity index. Which one to include and on what basis?

3. In one extract, more than 60 compounds are identified. Should I include them all for manuscript or can I select the important and bioactive compounds only?

Very much thankful for your help!

I am searching for alternative words for the term PHARMACONOSY.
